The 2011 Major League Baseball season began on Thursday, March 31, and ended on Wednesday, September 28. This marked the first time a season began on a Thursday since 1976, and the first time a regular season ended on a Wednesday since 1990. The 82nd edition of the Major League Baseball All-Star Game was played at Chase Field in Phoenix, Arizona, on July 12 with the National League defeating the American League for the second straight year, by a score of 5–1. As has been the case since 2003, the league winning that game has home field advantage in the World Series. Accordingly, the 2011 World Series began on October 19, and ended on October 28, with the St. Louis Cardinals winning in seven games over the Texas Rangers.
Only two teams were unable to complete the entire 162-game regular season schedule, as the make-up game between the Los Angeles Dodgers and the Washington Nationals at Nationals Park on September 8 was cancelled due to rain and was decided not to make up any further, owing to scheduling constraints and the game inconsequential to the playoffs.

Game 162 
||It has been suggested that this section be split into a new article titled Game 162. (Discuss) Proposed since February 2013.|
On the last day of the 2011 regular season, the post-season fate of four teams across both leagues was decided. In the National League, the St. Louis Cardinals defeated their National League Central division rival Houston Astros to win the National League wild card berth after the Atlanta Braves lost to their National League East division rivals, the Philadelphia Phillies. In the American League, the Tampa Bay Rays defeated their American League East division rivals the New York Yankees with dramatic home runs in the 9th inning by Dan Johnson and later in extra innings by Evan Longoria to win the American League wild card berth after the Baltimore Orioles defeated the Boston Red Sox, both also rivals in the American League East, on a walk-off single. This has been cited as the "most thrilling 129 minutes in baseball history." Tom Verducci wrote:
- They will go down as the most thrilling 129 minutes in baseball history. Never before and likely never again -- if we even dare to assume anything else can be likely ever again -- will baseball captivate and exhilarate on so many fronts in so small a window the way it did September 28, 2011.
The Rays returned to the playoffs for the second consecutive year despite losing many players from the year before. The Red Sox and Braves suffered two of the most epic collapses their franchises had due to their losing the playoff spot the last day despite leading the next contending teams by multiple games the last month of the season. The Cardinals eventually rode the momentum of their win to win the NLDS and NLCS on their way to defeating the Texas Rangers for their 11th World Series title in the 2011 World Series.
American League wildcard race 
Boston Red Sox at Baltimore Orioles 
|WP: Jim Johnson (6–5) LP: Jonathan Papelbon (4–1)
BOS: Dustin Pedroia (21)
BAL: J. J. Hardy (30)
Notes: The game was delayed in the middle of the 7th for 1:26 due to rain
The Red Sox were favored by pundits to win the American League pennant prior to the start of the season due to acquisitions of Adrian Gonzalez, Carl Crawford and Bobby Jenks. Despite a slow start, Boston darted to the top of the division during the summer months. Injuries plagued the team and they slowly lost first place to the Yankees, but were still in comfortable contention for the wild card. The month of September started an epic slump for the team where the team had allowed the Rays to get back into contention. However, Boston still controlled its own destiny going into their final series with the last place Orioles, but wound up having the season come down to the last game.
The Red Sox had taken a lead for a good part of the game, but the Orioles mounted a comeback. The game was interrupted by a rain delay in the middle of the 7th with Boston ahead 3–2. After play had resumed almost an hour and a half later, the Orioles still trailed by a run in the bottom of the 9th. When leading after eight innings, the Red Sox were 77–0 in 2011. Facing closer Jonathan Papelbon, Chris Davis and Nolan Reimold hit back-to-back doubles with two outs, which tied the game. The next batter, Robert Andino, hit a line drive to left field which Carl Crawford was unable to catch, allowing Reimold to score and the Orioles walked off with the win.
New York Yankees at Tampa Bay Rays 
|WP: Jake McGee (5–2) LP: Scott Proctor (2–6)
NYY: Mark Teixeira 2 (39), Andruw Jones (13)
TB: Evan Longoria 2 (31), Dan Johnson (2)
The Yankees had already won the American League East several days prior to this contest. The Rays had been in third place behind both the Yankees and the Red Sox for much of the season. However, Boston had slowly started to lose many games in September due to poor starting and relief pitching, disappointing hitting from newly acquired free agent Carl Crawford throughout the year, and injuries to key players like Kevin Youkilis. The Rays, who had won the division in 2010, had lost many of their players to free agency. Despite the losses, the Rays had crawled back into contention and faced the Yankees in the final series of the year.
Yankees manager Joe Girardi indicated that he would approach the final games so that the team's pitching staff would be set up for the 2011 ALDS against the Detroit Tigers. Suspicions rose to whether or not the Yankees would compete intensely due to them wanting to rest their aging players for the playoffs and to keep the Red Sox out, their fierce rivals whom they had a lopsided losing record to that season. Girardi indicated that many of his post-season pitchers would not be pitching that game. The Yankees, however, started the game strong by taking a 5–0 lead by the 2nd inning. Their lead grew to 7–0, which they held as the game entered the bottom of the 8th inning. In the 8th inning, the Rays scored six runs, capped off by a three-run home run by Evan Longoria. In the bottom of the 9th inning, down to his final strike, struggling Rays first baseman Dan Johnson hit a solo home run to tie the game. Already depleted from wanting to get pitchers who were not going to be on the post-season roster in, the Yankees went into extra innings with struggling pitchers. During Tampa Bay's half of the 12th inning, Evan Longoria hit his second home run of the game, a walk-off home run that cleared a short wall near the left field foul pole to win the game for the Rays just minutes after the Orioles' victory over the Red Sox. The win clinched the American League Wild Card for the Rays.
National League wildcard race 
The National League wildcard race came down to the fate of two games on the last day of the regular season.
St. Louis Cardinals at Houston Astros 
|WP: Chris Carpenter (11–9) LP: Brett Myers (7–14)
STL: Allen Craig (11)
The National League Central had been a two way race late into the season with the Cardinals and Milwaukee Brewers vying for contention. After the Reds had fallen off, the Brewers had clinched the division. The Cardinals battled back despite perennial all-star Albert Pujols serving on the disabled list and not having pitcher Adam Wainwright. Upon Pujols' return, the Cardinals came within one game by defeating the Astros under nine innings of dominant pitching by ace pitcher Chris Carpenter.
Philadelphia Phillies at Atlanta Braves 
|WP: Justin De Fratus (1–0) LP: Scott Linebrink (4–4) Sv: David Herndon (1)
ATL: Dan Uggla (36)
The Philadelphia Phillies had clinched a playoff berth, the division title, and the best league record for weeks. For most of the season, the Atlanta Braves had been in 2nd place in the National League East by a good margin and well ahead in the wildcard standings. The Phillies had something to play for, a franchise record in wins. They battled back to force the game into extra innings where they won and in effect, not only eliminated the Braves from post-season contention, but also set that record with 102, surpassing the previous record of 101 set back-to-back in 1976 and 1977 during their run of three straight division championships from 1976–1978. Charlie Manuel also became the winningest manager in the history of the Phillies with 646 wins, surpassing Gene Mauch, the manager of the Phillies when they collapsed in a similar way the Braves did in 1964.

New Rivalry 
The St. Louis Cardinals and the Milwaukee Brewers squared off in a season long division race and by the beginning of August, they were only a few games apart in the division. The Brewers would pull away for the crown, and the Cardinals continued poorly until they were 10 1⁄2 games back of the wild card on August 25. They made a historical comeback in September to win the wild card from the Atlanta Braves on the last day of the season. Both teams would advance through the NLDS in five games setting up a 1982 World Series rematch. The Cardinals won the pennant in six games, clinching the series on the road.

Field managers 
Four teams announced that a new manager will be hired for the 2011 season after the former manager retired from baseball.
|Team||Former manager||New manager||Story|
|Atlanta Braves||Bobby Cox||Fredi González||Cox announced in 2009 that the 2010 season would be his last as manager of the Braves. In two terms, first from 1978 through 1981 and from mid-1990, replacing Russ Nixon as manager through 2010, Cox has led the team to fourteen division titles, five pennants and the 1995 World Championship. Cox retires as the manager with the fourth highest number of wins (2,504) along with the most ejections in baseball history (158).|
|Chicago Cubs||Lou Piniella||Mike Quade||After six decades in baseball as a player, coach, manager and television commentator, Piniella announced on June 19, 2010, his intentions to retire. He has managed the New York Yankees, the Cincinnati Reds (including their 1990 World Series championship), the Seattle Mariners (including a record 116 win season in 2001), the Tampa Bay Devil Rays and the Cubs. The official retirement came on August 22 as Piniella stepped down due to his mother's failing health, and Quade, the Cubs' third base coach, was named interim manager, and was named permanent manager October 19.|
|Los Angeles Dodgers||Joe Torre||Don Mattingly||Torre announced on September 17 that he would not be returning to the Dodgers for the 2011 season. With his contract expiring and club ownership being contested in divorce court, Torre chose not to negotiate an extension. At the same time, the Dodgers announced that Mattingly, the team's hitting coach, will be promoted to manager. Mattingly was best known as an outstanding first baseman with the New York Yankees.|
|Toronto Blue Jays||Cito Gaston||John Farrell||After being lured out of retirement by team president Paul Beeston, Gaston announced on October 29, 2009, that he would step aside after the completion of the 2010 season and remain in a consulting position. In his first term as the Jays' skipper, he led the team to their greatest success, winning back-to-back Fall Classic in 1992 and 1993. His second term started as he replaced John Gibbons in the middle of the 2008 season. Farrell comes over after serving as the pitching coach for the AL East rival Boston Red Sox.|
At the end of the 2010 season, three teams fired their managers and made replacements:
|Team||Former manager||New manager||Story|
|Milwaukee Brewers||Ken Macha||Ron Roenicke||Macha announced to the Associated Press that the Milwaukee Brewers had declined to pick up his Club Option for 2011. Roenicke was named in November 2010 as the team's new field leader coming over from the Los Angeles Angels serving 11 seasons as Mike Scoscia's third base coach.|
|New York Mets||Jerry Manuel||Terry Collins||Manuel, along with general manager Omar Minaya, were fired following the end of the 2010 season on October 4, 2010. Since making the 2006 National League Championship Series, the team has fallen short of expectations, which include back to back season ending collapses in 2007 and 2008, followed by back-to-back injury plagued seasons in 2009 and 2010. Collins, a fiesty and intense manager, was named the team's new manager November 2010 and returned to being a field manager in the majors after 12 years. He previously managed the Houston Astros and the Anaheim Angels from 1994 to 1999.|
|Pittsburgh Pirates||John Russell||Clint Hurdle||Russell was fired after three losing seasons, compiling a total record of 186–299 in those three seasons. The Pirates have not had a winning season since 1992, which was also the last time they made the playoffs. They have also endured six different managers during that span. Hurdle last managed the Colorado Rockies in 2009 before being replaced.|
The following managers who were interim managers for 2010 will lead their respective teams in 2011:
|Team||Manager that started 2010 season||Replacement||Story|
|Arizona Diamondbacks||A. J. Hinch||Kirk Gibson||Gibson, who started the season as bench coach, filled in for the final 83 games. New GM Kevin Towers made the decision to keep Gibson as the manager for 2011. Hinch was "demoted" from his position as Director of Player Development in 2009 when he took over for Bob Melvin.|
|Kansas City Royals||Trey Hillman||Ned Yost||After coming to Kansas City to be a consultant, the Royals named Yost on May 13 to replace Hillman. Prior to that, Yost served as manager of the Milwaukee Brewers for much of the 2008 season, only to be sacked in mid-September when the team was struggling to make the post-season. Hillman had previous success in Japan, leading the Hokkaido Nippon Ham Fighters to the Japan World Series championship in 2006.|
|Baltimore Orioles||Dave Trembley;
Juan Samuel (interim)
|Buck Showalter||The no-nonsense Showalter, who had previously managed the New York Yankees, the Texas Rangers and the Arizona Diamondbacks on the brink of success before being replaced, served as a commentator for ESPN's Baseball Tonight before agreeing to return to the dugout with the Orioles on August 3, and turned the fortunes of the Maryland ball club. Trembley was in the manager's seat until June 4, when third-base coach Samuel replaced him on an interim basis before Showalter's arrival.|
|Florida Marlins||Fredi González||Edwin Rodríguez||On May 23, González, who had coached under Bobby Cox in Atlanta, was fired from his position. Rodríguez had spent the past 1½ years managing the New Orleans Zephyrs, the Marlins' Triple-A affiliate. Cox made discouraging comments about the handling of the dismissal shortly afterward, and as a result, was not honored by Marlins owner Jeffrey Loria when the Braves visit to Miami in September as part of Cox's retirement tour.|
|Chicago Cubs||Lou Piniella||Mike Quade||(See Above)|
One team has hired a new manager:
|Team||Manager that started 2010 season||Interim Manager||Replacement||Story|
|Seattle Mariners||Don Wakamatsu||Daren Brown||Eric Wedge||Wakamatsu, the first MLB manager of Asian-American decent, was fired on August 9 and replaced by Brown, at the time in his fourth season managing the Mariners' AAA affiliate, the Tacoma Rainiers. The team was expected to contend for the American League West title with the addition of Chone Figgins and Cliff Lee, but stumbled out of the starting gate. Wedge, who last managed with the Cleveland Indians in 2009, was reportedly hired by the Mariners according to a report by SI.com on October 15, 2010, and made official three days later.|
In-season changes 
|Date||Team||Former manager||Reason||Replacement||Previous Job and Story|
|June 9||Oakland Athletics||Bob Geren||Fired||Bob Melvin||Melvin previously was the manager of the Arizona Diamondbacks. Geren was fired after June 8 game.|
|June 19||Florida Marlins||Edwin Rodríguez||Resigned||Jack McKeon||After a losing streak and slump in June, Rodriguez announced his resignation on June 19. McKeon at age 80 became the oldest manager since Connie Mack to manage in the majors; he had won the 2003 World Series with the Marlins. McKeon announced his second retirement allowing Ozzie Guillén to become Marlins' skipper.|
|Washington Nationals||Jim Riggleman||Resigned||Davey Johnson
|McLaren, who was previously the Nationals bench coach, was named interim manager, but he is not expected to fill the role for the remainder of the season. Davey Johnson was named the full-time manager three days after Riggleman resigned and two days after McLaren was named interim manager.|
|September 26||Chicago White Sox||Ozzie Guillén||Released||Don Cooper||Guillen was released from his contract after the White Sox game on September 26 against the Toronto Blue Jays. Guillen became the Marlins new manager with the retirement of Jack McKeon at the end of the season. Cooper, the current pitching coach for the White Sox, managed the final two games of the season.|

Angels' 50th anniversary 
The Los Angeles Angels celebrated their 50th Anniversary in 2011. Founded by Gene Autry in 1961, the team played at Los Angeles' Wrigley Field in their first season, then shared Dodger Stadium (called "Chavez Ravine" by Angels management) with the Dodgers before moving to Anaheim in 1966 and their own stadium, Anaheim Stadium (later to become Edison International Field of Anaheim and finally Angel Stadium of Anaheim). That year, the team name was altered to the California Angels. After being purchased by The Walt Disney Company in 1997, the team name was changed to the Anaheim Angels and after Arte Moreno purchased the team, the name was changed to its current moniker to the Los Angeles Angels of Anaheim in 2005. For the season, in addition to the patch, the Angels changed the color of the halo from silver to gold on their uniforms, just as it looked from 1971 through 1996. In addition, on selected Friday night games, the team donned replicas of five of the six styles of uniforms they have worn, the most notable omission being that of the "Periwinkle Blue" era from 1997 to 2001, when Disney owned the team.
Venue changes 
Due to the U2 360° Tour concert scheduled June 29 at Sun Life Stadium and the needed time to set up the stage, the Marlins were forced to move their scheduled home games for June 24–26 against the Seattle Mariners to the Mariners' park at Safeco Field. As the Marlins were the home team, NL rules (no designated hitter) were applied. Mariners and Marlins would not meet again in Miami until 2014.
