Jacob Tanner Diekman (born January 21, 1987), is an American professional baseball pitcher for the Oakland Athletics of Major League Baseball (MLB). He has previously played for the Philadelphia Phillies, Texas Rangers, Arizona Diamondbacks, and Kansas City Royals.
With the Phillies, Diekman began as a starting pitcher and progressed through a few levels of the Phillies' farm system in his first two years in that role, before adjusting his mechanics and lowering his arm slot to throw sidearm out of the bullpen, as a relief pitcher. The adjustment worked and helped him move through the remaining levels of the Phillies' farm system. In 2012, Diekman made his major league debut. Over the next two seasons, he split time between the major league Phillies and their Triple-A (AAA) affiliate, the Lehigh Valley IronPigs, though while he was with the major league team, he was considered one of the "lone bright spots" in both 2012 and 2013. Diekman throws a fastball in the upper-90s (mph), a slider, and an occasional changeup; his fastball is among the fastest of any left-handed reliever in the major leagues.
Diekman was born to Paul and Billie Diekman, in 1987. He has one brother, Brian. The Diekmans lived in Wymore, Nebraska, where Jake attended Southern High School. His alma mater was too small to field a baseball team, so he instead focused on golf. Eventually, Diekman joined an American Legion baseball team, playing in the summer with other players from Wymore and several surrounding towns, which he called "the best experience of my life ... so much fun." Concurrently, Diekman worked full-time at a lawn mower factory, to earn money to pursue a post-secondary education.
After graduating from high school, Diekman enrolled at Doane College, pitching one season for the school’s ball team. He then transferred to Cloud County Community College, in Kansas. Following Diekman‘s sophomore season, he attended a junior college baseball showcase at which, with a fastball well over 90 miles per hour (140 km/h), Diekman drew much interest. He received an offer for a full scholarship to be a Nebraska Cornhusker, which he would have accepted, had the Phillies not drafted him in the 2007 Major League Baseball Draft's 30th round.
Between 2007 and 2010, he pitched in the lower levels of the Philadelphia Phillies' Minor League system initially as a starter, and subsequently as a reliever. Although he initially saw success in 2007, posting a 2.72 ERA in 10 starts with GCL Phillies and Williamsport Crosscutters, he struggled in 2008, posting an ERA of 5.09 in 27 starts, split between Williamsport and the Lakewood BlueClaws. At the conclusion of both 2008 and 2009, he pitched in the Florida Instructional League to continue honing his skills on the mound.
He converted from a starting pitcher to a reliever in 2009, along with several other Phillies pitching prospects. Around that time, he also, at the suggestion of the same minor league pitching coaches who converted him to relief, lowered his release point to his current low angle. Success did not manifest itself immediately, as he still posted a 4.04 ERA in 2009, his first season in relief, but in 2010, he cut his ERA to 2.91 while splitting time between Lakewood and the Clearwater Threshers, the Phillies High-A affiliate. At the end of the 2010 season, he played for the Mesa Solar Sox in the Arizona Fall League. He spent the 2011 season with the Double-A Reading Phillies, accruing a 0–1 record and a 3.05 ERA and 3 saves in 53 games. Thereafter, the Phillies added him to their 40-man roster to protect him from the Rule 5 draft.
After receiving praise from Phillies' pitching coach Rich Dubee for his performance in spring training, Diekman opened the 2012 season with the Triple-A (AAA) Lehigh Valley IronPigs. With Lehigh Valley, he posted a 1–0 record and a 0.59 ERA with 5 saves in 13 games in the season's first month. He was added to the Phillies' 25-man Major League roster on May 11, and four days later recorded a win against the Houston Astros in his MLB debut. He finished the year an established lefty specialist, and had a 3.95 ERA, though walked 6.6 batters per 9 innings, and was erratic in his control.
Entering 2013, Diekman was expected to be a key part of the Phillies bullpen after his success in 2012, however he did not break camp with the big league club, beginning the season in AAA. In AAA, he struggled, which delayed his arrival to the major league team until June. While with the big league club, he continued his dominance of left-handed hitters, however was not as good against right-handed hitters (a 150-point differential in opponent batting average and over 300 point differential in On-base plus slugging (OPS)). Diekman improved his control, which made him a presumptive member of the 2014 bullpen, as he was one of 2013's "lone bright spots" for the otherwise dismal Phillies' bullpen. Ultimately, he did make the Phillies' opening day roster as a member of the bullpen.
Early in the season, Diekman emerged as a reliable reliever in the Phillies' bullpen, and was used extensively by manager Ryne Sandberg. As the season progressed, Diekman was more successful against left-handed hitters than right-handed hitters, but was used against both in a variety of situations. On September 1, 2014, Diekman was one of four pitchers who combined for a no-hitter in the Phillies' 7-0 win over the Atlanta Braves in Turner Field. By the end of the season, the Phillies had one of the best bullpens in the league, and it consisted predominantly of young players such as Diekman. There was excitement from both Phillies' personnel and writers that the bullpen could remain solid for a long time because of young pitchers such as Diekman, Ken Giles, and Justin De Fratus. Moreover, Diekman and Giles had potential as closers should the Phillies trade Jonathan Papelbon. Overall, Diekman emerged as a name to be mentioned among the "elite" relievers of the National League, but was overused against right-handed batters, which hurt his statistics.
On July 31, 2015, Diekman was traded to the Texas Rangers along with Cole Hamels in exchange for Matt Harrison, Nick Williams, Jorge Alfaro, Jake Thompson, Alec Asher, and Jerad Eickhoff. He became an important bullpen piece in the Rangers' run to the playoffs in 2016. Diekman and the Rangers agreed to a one-year deal worth $1.225 million on January 29, 2016, and avoided arbitration. Diekman finished the 2016 season with a 4-2 record, 4 saves and a 3.40 ERA in 66 appearances. On January 25, 2017, Diekman underwent surgery for chronic ulcerative colitis. He only made 11 appearances towards the end of the season. In 2018, fully healthy, Diekman posted an ERA of 3.69 in 47 games. He struck out 48 batters in 39 innings.
On July 31, 2018, Diekman was traded to the Arizona Diamondbacks for Wei-Chieh Huang and Joshua Javier. The trade took place while the Diamondbacks and Rangers were facing off in a two-game series in Arizona. Diekman struggled after being acquired by Arizona, posting an ERA of 7.53 in 24 appearances. Diekman became a free agent following the 2018 season.
Kansas City Royals
On February 13, 2019, Diekman signed a one-year contract with a mutual option for 2020 with the Kansas City Royals. The deal is worth a reported $2.75 million guaranteed, plus performance incentives.

A lefty specialist, Diekman throws a fastball in the mid-90s, a slider at 78–81, and an occasional changeup to right-handed hitters. His fastball is among the fastest of left-handed relievers in the major leagues. Like most left-handed pitchers, particularly those who throw out of an arm angle similar to Diekman's, he is tough on left-handed hitters. In 2013, he held lefties to just a .368 OPS, though allowed a .765 OPS to right-handed hitters. Despite suggestions he remain a lefty specialist, he emerged in 2014 as a favorite middle reliever for manager Ryne Sandberg against both righties and lefties.
Diekman's mother died at age 57 just months before the Phillies drafted him. Diekman describes his father as his "best friend", and one who has helped him cope with his mother's death. His mother, Billie, was Diekman's "biggest fan" and had to order her husband, Paul, to stop pacing and watch Diekman pitch. Diekman has sought therapy to cope with the loss of his mother, and meditates and thinks about her during "The Star Spangled Banner" prior to each game.
(After his mother's death) Diekman started to appreciate the little things. The game slowed down when he had fun. He invoked his mother's spirit rather than avoiding it. 'The drive and determination she had for all the projects she did, how hard she worked, the dedication she had for her job,' Diekman said. 'It really paid off. It really came to me. I thought, 'If I have a job, I want to put in the time and dedication like she did.' ' That is how Billie Diekman's legacy perseveres. It is why a young man from tiny Wymore, Neb., will cherish Sunday's rendition of "The Star-Spangled Banner" at a baseball stadium...— Excerpt from "Phillies' Diekman Holds Memory of His Mother Close", by Matt Gelb, The Philadelphia Inquirer, May 11, 2014
Away from baseball, Diekman holds an associate's degree in business administration from Cloud County Community College. He enjoys listening to music, working out, and playing golf. He resides in Beatrice, Nebraska, during the offseason. Because of his struggles with ulcerative colitis, he started a non-profit association called Gut It Out to benefit others who struggle with the disease.
