Jay Dee "B.J." Penn (born December 13, 1978) is an American Mixed Martial Artist and Brazilian Jiu-Jitsu Practitioner. Penn debuted and competes in the Ultimate Fighting Championship. Prior to signing with the UFC, he became the first American and non-Brazilian winner of the World Jiu-Jitsu Championship. In mixed martial arts, Penn has competed in the lightweight, welterweight, middleweight and heavyweight divisions. As a former UFC Lightweight Champion and UFC Welterweight Champion, he is only the second fighter in UFC history to win titles in two different weight classes. During his tenures as champion, Penn also broke the then-record for title defenses in the UFC's lightweight division (which has since been tied).
Throughout his reign, B.J. Penn holds the distinction of being undefeated at lightweight for over eight years, breaking many of the UFC lightweight division records in the process. Penn is famously known for his willingness to fight the best available competition throughout his career, which involved moving up in multiple weight classes to do so. In early 2004, he became the only fighter in mixed martial arts history to be simultaneously ranked number one in the two different divisions; lightweight and welterweight.
UFC President, Dana White credits B.J. Penn as the man who brought popularity to the UFC's lighter weight divisions, stating that "There was a point in time when we first bought this company when people thought guys in the lighter weight divisions couldn’t be stars and couldn’t see pay-per-views. B.J. Penn was definitely that first crossover guy for us". He is widely recognized as the greatest lightweight in mixed martial arts history, and is often regarded as one of the greatest fighters in the history of the sport.
Penn was born to Jay Dee Penn, an Irish American and Loraine Shin, a third generation Korean-American. At the age of seventeen, Penn began training in Brazilian Jiu-Jitsu after being introduced to it by his neighbor, Tom Callos. Callos had put up fliers in local gyms looking for people to train with, and B.J.'s father Jay Dee Penn had called Callos and said his boys were interested. Callos then taught B.J. and his brother what he knew. Shortly thereafter, B.J. moved to San Jose, California to begin training at AKA with Dave Camarillo and Bob Cooke, who he lived with and became close friends with. It was here during his time in San Jose that he decided to pursue a career in martial arts (albeit not mixed martial arts at the time).
In 1997 Penn began training Brazilian Jiu-Jitsu under Ralph Gracie, eventually earning his purple belt from Gracie. At that point he moved to Nova União where he was eventually awarded his black belt in 2000 by Andre Pederneiras. A few weeks later he became the first non-Brazilian to win the black-belt division of the World Jiu-Jitsu Championship held in Rio de Janeiro, Brazil. While Penn's most well-known and prestigious achievement was placing first in the black belt division in the 2000 world championships, he had success at the Mundials in previous years. In 1999, at the age of 20, Penn finished 3rd, earning himself a bronze medal in the brown belt division, losing only to Fernando "Tererê" Augusto, and in 1998, earned a silver medal, placing 2nd in the blue belt division. Penn is thought to have earned the fastest black belt of all active Brazilian Jiu-Jitsu practitioners.
Ultimate Fighting Championship
His accomplishments in the World Jiu-Jitsu Championship caught the attention of the Ultimate Fighting Championship, which convinced him to switch to MMA. Penn made his mixed martial arts debut with the company on May 24, 2001 with a win over Joey Gilbert at UFC 31. He then demonstrated strong striking skills, knocking out lightweights Din Thomas and Caol Uno before suffering a decision loss in a championship fight against [[UFC Lightweight Champion[[, Jens Pulver. In 2003, after Pulver left the UFC and relinquished his title, a tournament to crown a new champion flopped when Penn fought Uno to a draw in the finals at UFC 41, a failure which caused the UFC to later suspend its lightweight division. Penn bounced back later in the year with a victory over future Pride Lightweight Champion Takanori Gomi, in Rumble on the Rock, an MMA organization promoted by Penn's brother.
Penn received his first MMA championship in 2004 at UFC 46. Penn jumped up in weight classes to challenge the five-time defending UFC Welterweight Champion Matt Hughes to fill a title contention slot in a division where Hughes had already defeated all the available opposition. Heavily favored to win, Hughes lost the fight four minutes into the first round by rear naked choke after giving up his back with only 23 seconds left in the round. This win remains as one of the biggest upsets, as well as one of the greatest submission victories in MMA history.
Fighting and Entertainment Group
Shortly after defeating Hughes, Penn signed to fight for the Japanese Fighting and Entertainment Group's (FEG) K-1 promotion citing a lack of challenging fights left for him in the UFC. The UFC promptly stripped him of the welterweight title, claiming Penn breached his contract and that the signing constituted him refusing to defend his title. Penn filed a suit against the UFC and publicized his side of the conflict, claiming his UFC contract had already expired. Penn filed a motion to stop the UFC from awarding a new welterweight title, but that motion was denied.
In his first fight for FEG, Penn fought again at welterweight (170 pounds) and defeated Duane Ludwig at the 2004 K-1 MMA Romanex show in under five minutes by arm triangle choke. Following the Ludwig fight, Penn moved up in weight class to face the undefeated Rodrigo Gracie at middleweight (185 pounds). Penn won by decision, extending his winning streak to four fights. On March 26, 2005, at the inaugural event of FEG's new MMA promotion Hero's, Penn faced future UFC Light Heavyweight Champion Lyoto Machida, losing by unanimous decision at K-1 Hero's 1. The fight happened at an open weight class with Penn weighing in at 86.5 kilograms (191 lb) and Machida 102 kilograms (220 lb). Later that year at K-1 World Grand Prix Hawaii, Penn returned to middleweight to face Renzo Gracie and won by unanimous decision.
Return to the UFC
In early 2006 at UFC 56, UFC president Dana White announced that Penn and the UFC had agreed to a settlement and Penn was to return as a top welterweight contender. Penn re-debuted on March 4 at UFC 58, losing to Georges St. Pierre by split decision in a fight that determined the number one welterweight contender. Although St. Pierre was declared the winner after a three round decision, many believed that Penn had done enough to earn himself the victory, causing noticeably more damage throughout the fight, as Joe Rogan described Georges St. Pierre’s face being “a bloody mess” while B.J. Penn “barely having a scratch on him." Despite having lost the bout, Penn's performance against Georges St. Pierre, is considered to be one of the best put forth against the future UFC Champion.
After new top contender St. Pierre injured himself during training, the UFC announced that Penn would replace St. Pierre in an upcoming title fight, setting up a highly anticipated rematch with Hughes for UFC 63 on September 23, 2006.In the bout, Penn controlled the first two rounds, but sustained a rib injury during the scramble to take Hughes' back in round two. He was visibly different in the third round, appearing exhausted and missing punches he was landing earlier. Hughes was able to take Penn to the mat, and in side control crucifix position rained punches on Penn's head until referee "Big" John McCarthy stopped the fight at 3:53 of the third round, making this the first time that Penn had been stopped in a fight. In an interview found on Penn's personal website, Penn stated that by round three he could hardly breathe and had no "mobility in his core." Despite the injury, Penn congratulated Hughes, calling him a great fighter and saying he deserved the victory.
Penn was a coach for The Ultimate Fighter 5, which aired on April 5, 2007. Penn lead a team of eight lightweight fighters, and fought a rematch against Jens Pulver at the conclusion of the series on June 23, 2007. He won with a rear naked choke in the second round after controlling Pulver from the mount and then taking Pulver's back. Although he held the choke for a moment after Pulver tapped out, the two then embraced, with both later saying they no longer held any ill will against each other.
On July 7, 2007, during the post-fight press conference of UFC 73, UFC president Dana White announced that Penn would stay at lightweight to fight current UFC lightweight champion Sean Sherk. However, Sean Sherk subsequently was suspended by the California State Athletic Commission, and the status of the possible title fight was left in limbo as he pursued his appeals. With Sherk's title status still in limbo after months of hearings, the UFC scheduled Penn to fight Joe Stevenson at UFC 80 on January 19, 2008 for an interim lightweight title. The subsequent final decision by the California State Athletic Commission, which did not overturn Sherk's suspension, led to the title being stripped from Sherk and the Penn-Stevenson fight being upgraded to a full title bout, with the winner facing Sherk in their first defense.
Penn knocked Stevenson down seconds into the first round with a right uppercut, then took Stevenson down, delivering a well placed elbow from the top position that inflicted a serious cut near Stevenson's hairline. In the second round, Stevenson fought more aggressively but was still unable to threaten Penn. Penn worked to back mount and defeated him by rear naked choke at 4:02 of the second round to win the Lightweight Championship. He celebrated the win by licking Joe Stevenson's blood off of his gloves. The win for Penn was awarded Beatdown of the Year by Sherdog for 2008. With this win, Penn became the second man (after Randy Couture) to win UFC titles in two different weight classes.
On May 24, 2008 at UFC 84 at the MGM Grand Garden Arena in Las Vegas, Nevada, Penn fought former champion Sean Sherk in his first title defense bout. The fight was billed by play-by -play commentator Mike Goldberg as the "biggest fight in the history of the UFC lightweight division". Sherk attempted to take Penn down only once (in the first round), instead the fighters traded punches and leg kicks for the remainder of the fight. Penn landed jabs several times, utilizing his reach advantage over Sherk. In the closing seconds of the third round, Penn threw a punch and a hook that backed Sherk into the cage. Sherk then ducked under another punch – possibly to shoot for a takedown – when he was hit in the head by a flush flying left knee from Penn. Sherk went down and Penn continued with strikes, but the round ended before the referee stopped the fight. However, Sherk was unable to continue and Penn was declared the victor by TKO (strikes). After the fight, in response a question by Joe Rogan about his future, Penn asked the crowd if they wanted to see him fight Georges St. Pierre and was answered with a loud ovation. Later, Penn told Fighters Club TV that he would face the winner of UFC 87 Welterweight title fight between Georges St-Pierre and Jon Fitch, which St-Pierre ended up winning by unanimous decision. St-Pierre's victory led to the scheduling of B.J.'s next fight as a Welterweight Championship fight.
Welterweight title shot
Penn challenged Georges St-Pierre for St-Pierre's welterweight title on January 31, 2009, the night before the Super Bowl. The date led UFC 94 to be billed as the "UFC Super Bowl Weekend," and it was anticipated to be the biggest UFC pay-per-view event ever. Before the fight with St-Pierre, Penn made a controversial comment that he was going to try to kill St-Pierre in the ring, but he later explained that he was speaking figuratively.
The first round of the fight was somewhat even, with Penn exercising elusive head movement, fast hands and good take-down defense, thwarting all of St-Pierre's take-down attempts while both exchanged punches. In the ensuing three rounds, however, Penn turned out a lackluster performance. St-Pierre scored his first take-down of the night midway through the second round, and by the end of the round Penn was visibly tired. At the start of round three, St-Pierre landed a "superman punch" that bloodied Penn's nose and shortly took Penn down again. From that point on, St-Pierre took Penn down almost at will, repeatedly passed Penn's renowned guard, and persistently punished the Hawaiian with a ground-and-pound attack. Penn later admitted that he could not recall anything that happened during the 3rd and 4th rounds because "I was probably borderline knocked out or something." At the end of the fourth round, after more of St-Pierre's ground-and-pound onslaught, Penn's brother requested that the referee stop the fight. After the fight, Penn failed to attend the post-fight press conference due to having stayed in the hospital. Subsequently in an interview he revealed that had he won, he would have retired "on top", while holding the lightweight and the welterweight belts.
A controversy arose during the fight as St-Pierre's corner-men were spotted rubbing St-Pierre's back immediately after applying Vaseline to his face. Members of the Nevada State Athletic Commission (NSAC) came into the octagon and attempted to wipe St-Pierre's torso down. After the fight, on ESPN's MMA show, St-Pierre claimed that the rubbing was part of a routine to line up his energy for improved breathing, and he apologized for any Vaseline that may have been transferred to his body. Penn, however, sent a formal request to the NSAC, asking them to investigate. Despite all of the complaints by the Penn camp, the NSAC decided to take no action. This incident was famously coined by mma fans and media as the "Greasegate" and remains as one of the biggest controversies in MMA history.
In response to the incident, the rules of the UFC were modified so that only the official "cut men" would be allowed to have or apply Vaseline to the fighters. The procedures governing the transition from the fighters walk-in to the cage and while in the cage were also changed. Previously, fighters would walk up next to the cage, see the cut man who would apply Vaseline, be checked by the referee, and then have an opportunity to speak with or hug their coaches or cornermen before entering the cage. To prevent an opportunity for the fighters to have Vaseline applied illicitly, fighters now must first part from any company, have Vaseline applied by the cut man, be checked by the referee, and then go directly to the cage. Finally, no cornermen will be allowed to have Vaseline in the cage between rounds. In this way, the fighter's contact with Vaseline is fully controlled by the cut men and referee, who work independently for the UFC.
UFC President Dana White said that the incident had no effect on the outcome of the fight although he wished the incident had not happened. In his first post-fight interview Penn spoke of his belief that if St-Pierre were found to have been "greased" he would lose all respect for him, while admitting that "[I] definitely got my butt kicked." Penn claims that before the match he warned the NSAC that St-Pierre might use grease intentionally. St-Pierre responded to the allegations by offering to fight a rematch against Penn. Penn went on record as accepting the offer for a re-match. Following his informal acceptance of a proposed second rematch, Penn filed a formal complaint with Nevada State Athletic Commission seeking to prevent St-Pierre from fighting by suspending St-Pierre's fighter's license. In addition, Penn requested the suspension of St-Pierre's cornermen, Greg Jackson and Phil Nurse, a fine of $250,000, and overturning the result of the fight to a no-contest. The NSAC has since then instituted new rules that will not allow foreign substances in the cage, coined "The B.J. Penn Rule" by some of the NSAC officials.
UFC 101 and return as Lightweight Champion
Penn began negotiations to fight Kenny Florian in the summer of 2009. The Florian-Penn title fight was scheduled for UFC 99, but B.J. Penn requested more time off after his fight with GSP. He defended his title against Florian on August 8, 2009 at UFC 101. Penn looked noticeably in better physical shape than his previous outings at 155 lbs and negated any sort of takedown offense from Florian the entire match despite his opponent's persistence in grappling and engaging the clinch.
On his feet, Penn avoided virtually any damage, constantly stuffing or evading any attempts of a left high kick, punches, or elbows from Florian when the two departed from the clinch. In a measured performance, Penn preferred to pace himself in his standup, occasionally showing explosive bursts of striking up until the fourth round, where he executed a powerful takedown and quickly assumed the half guard position, punishing the contender with elbows until gaining the full mount, where punches followed to continue the ground and pound assault from the BJJ specialist.
A scramble ensued, where Florian gave up his back twice but was unable to escape Penn's mount, the second time Penn took his opponent's back, he looked to trap Florian's arm with one of his legs, but was unable to do so, instead striking the liver of Florian with his heel, which eventually led Penn to secure a rear naked choke at 3:45 of the fourth round to defend his lightweight championship title.
Penn fought Diego Sanchez for the UFC Lightweight Championship on December 12, 2009 at UFC 107. Penn negated virtually any offense from the contender, exercising good footwork and elusive head movement whilst remaining flawless in his takedown defense on 27 attempts from Sanchez. He stalked his opponent for large periods of the match and stunned Sanchez early, dropping him; following up with multiple clean shots, which Sanchez showed good durability in weathering. Penn, showing good conditioning for the duration of the bout, continued to stuff all takedowns, punches and left high kicks from Sanchez and dominated with aggressive bursts of striking throughout. He hurt Sanchez several times, until finally rocking him with a flurry in the final round, swarming to finish the combo with a right high kick. The kick opened up a huge cut on Sanchez's forehead above his left eye, causing the fight to be halted on doctor's advice at 2:47 of the fifth round with a TKO. This also marked only the second fight in UFC history to end in the fifth round.
The performance marked the third time Penn had successfully finished a fight in defending his UFC Lightweight Championship, setting a new record of lightweight title defenses, by breaking the previous record of two defenses by Jens Pulver. Later during the post-fight press conference UFC President Dana White told the media he was proud of Penn's willingness to take MMA more seriously in his training when earlier he felt Penn had coasted through the UFC solely on natural talent.
Losing the title
Penn's next defense was on April 10, 2010 at UFC 112 against Frankie Edgar. Despite being an overwhelming favorite coming into the fight, Penn lost the closely contested bout by unanimous decision; breaking his eight year undefeated streak in the lightweight division. After the fight, Penn congratulated Edgar on winning the belt and claimed that he had not felt quite right in the octagon. The majority MMA fans and media outlets were shocked by the judges decision after the five round fight, having believed that Penn had clearly done enough to earn himself the victory. Reputable mixed martial arts websites such as MMAFighting went as far as claiming that "the 50-45 score is ridiculous." Due to the controversy surrounding the decision, an immediate rematch was later booked.
Penn fought Edgar in a rematch at UFC 118. During the bout he was taken down three times during the first two rounds – and though Penn took Edgar down twice in the final two rounds – Edgar was able to negate his ground offense and control the fight with good movement and striking combinations. All three judges scored the fight 50–45 for Edgar.
Return to welterweight and hiatus
Penn fought welterweight Matt Hughes at UFC 123 in a rubber match after their previous two fights at UFC 46 and UFC 63. Penn defeated Hughes in 21 seconds of the first round by knockout after flooring Hughes with a right hand and following with additional strikes on the mat. Penn earned knockout of the night honors for his performance.
|“||"You're my idol -- Matt Hughes, you're my idol, you will always be my idol, thank you." - B.J. Penn, post fight at UFC 123.||”|
Following the UFC 123 post-fight press conference, UFC president Dana White said that Penn would fight top welterweight contender Jon Fitch at UFC 127 in Australia. Penn trained with Matt Hughes and Floyd Mayweather, Sr. in preparation for the fight. Penn surprised Fitch by taking him to the ground instead of using his stand up skills. The fight ended in a draw and Penn stated that he would gladly have a rematch in the future. UFC matchmaker Joe Silva stated that neither the fans nor the UFC are interested in a Penn-Fitch rematch.
Penn was expected to face Carlos Condit on October 29, 2011 at UFC 137. B.J. Penn relocated his camp to Southern California in an effort to prepare for the bout. Penn was joined in California by former UFC middleweight and Ultimate Fighter winner Kendall Grove and B.J.'s brother Reagan Penn, as they both prepared for their August 27 fights on the ProElite show in Hawaii. However, on September 7, Condit was pulled from the bout and replaced Nick Diaz in the main event against Georges St. Pierre. Dana White stated that Penn will fight Nick Diaz in the main event at UFC 137 after GSP pulled out due to knee injury. Penn lost via unanimous decision after success in the first round with crisp counter-boxing and elusive head movement, even mixing in a take-down. Diaz found huge success with combinations to the body while pressuring him against the fence in the second, with B.J. slowing down and absorbing a considerable amount of punishment. He rallied in the third and even began walking Diaz down, while a closer round than the second stanza, Diaz still did enough to outpoint him two rounds to one.
Immediately following the loss to Diaz, Penn announced his plans to retire, saying into the microphone, "Joe, this was probably the last time you'll see me in here. I can't keep performing at the top level. That's it Joe. I got a daughter and another daughter on the way, I don't want to go home looking like this. I'm done." On November 1, Penn posted a message to fans on his website indicating that he plans to take some time off, but the retirement decision is not yet official. He said, "I want to thank all the fans for their love and support. I have decided to take some time off to enjoy life, train and teach. I will keep you guys posted with what’s next." A few months afterwards, B.J. tweeted angrily at both Jon Fitch and Nick Diaz, causing many to believe that Penn would be returning from his retirement within the near future. His manager has stated that the old B.J. is back and could be returning to MMA. In April 2012 UFC president Dana White said B.J. Penn turned down a fight with the reigning Strikeforce Lightweight Champion, Gilbert Melendez, and that Penn wants to continue at 170 pounds "whenever he is ready". White also said he feels that B.J. Penn deserves to be in the UFC Hall of Fame, stating that he was a pioneer for the lightweight division, at a time when many believed that there couldn't be any stars at 155 pounds.
Several months after declaring his retirement from mixed martial arts, B.J. Penn announced that he would be returning to the octagon after repeated challenges made by welterweight prospect Rory MacDonald; by simply stating, "Rory, I accept your challenge!". Initially, Penn was expected to face Rory MacDonald on September 22, 2012 at UFC 152. However, MacDonald pulled out of the bout after sustaining a cut to the forehead while training. Penn vs. MacDonald eventually took place on December 8, 2012 at UFC on Fox 5. Penn lost the fight via unanimous decision. After the fight Dana White stated that he'd like to see B.J. Penn retire from mixed martial arts, though Penn has stated a desire to return to the UFC's lightweight division.
His nickname "B.J." is a shortened version of another nickname "Baby Jay", which itself derives from the fact that Penn is the youngest of his brothers all named "Jay Dee Penn". B.J.'s father, who is Irish and English, named 3 of his 4 children "Jay Dee", while the fourth is Reagan. In order to avoid confusion each of the sons named "Jay Dee" goes by a nickname: "Jay", "Jay Dee", and "Baby Jay". Penn's mother, Lorraine Shin, is of Korean descent.
Penn takes much pride in his Hawaiian upbringing. His trainer Rudy Valentino had stated once that Penn played Hawaiian music during his entrances as a tribute to it; a tradition which Penn still continues. Penn has also stated that he identifies strongly with his Korean roots and has traveled to Korea to hold seminars. He also said that he gets his hot temper from his Korean side which helps him use this energy in his fights.
With his girlfriend Shealen Uaiwa, Penn has two daughters: Aeva Lili'u (born October 25, 2008), and Kulia (born on January 8, 2012). Penn is the co-author of Mixed Martial Arts: The Book of Knowledge, an instructional book on mixed martial arts fighting. Penn, along with Dave Weintraub, authored the autobiography Why I Fight: The Belt is Just an Accessory in 2010. The book debuted at #22 on the New York Times bestseller list. Penn appeared in the film Never Surrender in 2009.
