2021 American League Division Series
The 2021 American League Division Series were the two best-of-five-games series in Major League Baseball’s 2021 postseason that determined the participating teams of the 2021 American League Championship Series. The three divisional winners, seeded first through third, and a fourth team—determined by the AL Wild Card Game—played in two series. These matchups were:
- Tampa Bay Rays vs. Boston Red Sox : Red Sox win series 3–1.
- Houston Astros vs. Chicago White Sox : Astros win series 3–1.
Background
Seeds one through three were determined by regular season winning percentages among division-winning teams. The final team was the winner of the American League Wild Card Game, played between the league's fourth and fifth seeded teams.The Tampa Bay Rays clinched the American League East on September 26 and secured the AL's best record and home-field advantage throughout the AL postseason with a 100–62 record on September 28. It was Tampa's first 100-win season in franchise history. The Boston Red Sox defeated the New York Yankees in the Wild Card Game, 6–2, to advance to the ALDS. This was the third postseason matchup between the Red Sox and Rays. The previous meetings were the 2008 American League Championship Series and the 2013 American League Division Series. The Rays won the season series with the Red Sox, 11–8.
The Houston Astros clinched the American League West on September 30 and secured the second-seed in the AL postseason with a 95–67 record. The Chicago White Sox clinched the American League Central on September 23, and secured the third-seed in the AL postseason with a 93–69 record. Houston won the season series over Chicago, 5–2. This was the first ever League Division Series that featured a World Series re-match; the White Sox swept the Astros in the 2005 World Series, when Houston was a member of the National League. This also makes it the first time ever this has occurred in the American League, and only the second time ever, the first being in the 2011 National League Championship Series, when the 1982 World Series opponents, the Milwaukee Brewers and the St. Louis Cardinals, played each other, after the Cardinals beat the Brewers in the latter series, 29 years earlier.
The Rays made their third straight postseason appearance, the Astros made their fifth straight appearance, and this was the White Sox' second straight appearance. The Red Sox had last reached the postseason three seasons prior, when they won the 2018 World Series.

Tampa Bay vs. Boston
The Rays won the season series with the Red Sox, 11–8. This was the third postseason meeting between the franchises. Their previous postseason meetings were in the 2008 ALCS, won by the Rays in seven games, and in the 2013 ALDS, won by the Red Sox in four games.Game 1
Tampa Bay won the opening game of the series, 5–0. Boston starting pitcher Eduardo Rodríguez took the loss after allowing two runs on two hits and two walks in innings. Tampa Bay's other three runs were charged to Nick Pivetta, who pitched innings of relief. Randy Arozarena of the Rays walked against Pivetta in the seventh inning, advanced to third base on a double by Wander Franco, and then stole home against Josh Taylor, who had relieved Pivetta. With the steal, Arozarena became the first player in baseball history to hit a home run and steal home base at the same game during a playoff game. Tampa Bay starter Shane McClanahan earned the win, pitching five innings while allowing five hits, no walks, and striking out three batters. Arozarena and Nelson Cruz both homered for Tampa Bay; Cruz's home run was given after it ricocheted off one of the catwalks along the stadium roof. The Red Sox outhit the Rays, 9–6, but went 1-for-7 with runners in scoring position.Game 2
Boston evened the series at 1–1 with a 14–6 win in Game 2. After the Red Sox scored twice in the top of the first inning, the Rays scored five runs off of Chris Sale in the bottom of the inning, including a grand slam by Jordan Luplow. The Boston bullpen, led by five innings from Tanner Houck, allowed just one more run by Tampa Bay—a home run by Ji-man Choi—for the rest of the game. Meanwhile, the Red Sox scored 12 more runs and had five batters with three or more hits. Kiké Hernández had five hits including a home run and three doubles. Xander Bogaerts, Alex Verdugo, J. D. Martinez, and Rafael Devers also homered. Houck got the win in relief for Boston, while Tampa Bay reliever Collin McHugh, who allowed three runs on two hits and a walk in innings, took the loss.Game 3
Boston took a 2–1 lead in the best-of-five series with a 6–4 win in a 13-inning contest, only the second postseason extra-inning game the Rays had ever played, and the second-longest AL postseason game ever. The Rays scored twice in the top of the first inning, via a two-run homer by Austin Meadows. The Red Sox got a run back in the bottom of the inning on a Kyle Schwarber solo homer. Boston went ahead, 3–2, on four consecutive singles that scored two runs in the bottom of the third, and extended the lead to 4–2 via a fifth-inning solo home run by Kiké Hernández. In the top of the eighth, Wander Franco homered and Randy Arozarena hit an RBI double, both off of Hansel Robles, as the Rays tied the game, 4–4.After a scoreless ninth inning, the game went to extra innings. Nick Pivetta, expected to be Boston's starting pitcher in Game 4, came on in relief and held the Rays scoreless in the top of the tenth, while the Rays' David Robertson held Boston scoreless in the bottom of the inning. Both Pivetta and Robertson stayed in the game and pitched a scoreless 11th inning. Pivetta again held the Rays scoreless in the top of the 12th, while Luis Patiño held the Red Sox scoreless in the bottom of the inning. The final 13th inning proved to be a wild one. Pivetta pitched a fourth scoreless inning, which included a ground rule double by Kevin Kiermaier—the batted ball bounced off of the right field wall, the ground, and then off of Hunter Renfroe's hip into the bullpen—which otherwise would have resulted in a Rays run, as Yandy Díaz was running from first base when the ball was hit. Christian Vázquez ended the game with a two-run walk-off home run off of Patiño in the bottom of the 13th.
This is, to date, the final postseason game broadcast by MLB Network. Broadcast television network Fox would assume the broadcasting rights to MLB Network's slate of Division Series games beginning in 2022, joining sister network FS1 as part of Fox Sports' MLB broadcast package.
Game 4
The Red Sox won Game 4, 6–5, to advance to the ALCS. Eduardo Rodríguez, who had lost Game 1 but only threw 41 pitches, started for Boston, while Collin McHugh, who had lost Game 2 in relief, started for Tampa Bay. After two scoreless innings, Boston scored five runs in the bottom of the third off Shane McClanahan, including a three-run homer by Rafael Devers. After all five runs were scored from Boston, Shane was then taken out after 2 innings in frustration, throwing his glove and smashing a chair inside the Rays' bullpen. The Rays got one run back in the top of the fifth. In the top of the sixth, a two-run homer by Wander Franco cut Boston's lead to 5–3. The Rays opened the eighth with three consecutive hits off of Ryan Brasier to tie the game, 5–5; Garrett Whitlock relieved Brasier and ended the rally. An outfield assist by Kevin Kiermaier cut down Alex Verdugo at third base to end a Red Sox threat in the bottom of the eighth. Whitlock then retired the Rays in order on seven pitches in the top of the ninth. Christian Vázquez led off the bottom of the ninth with a single against J. P. Feyereisen, he then reached second on Christian Arroyo's sacrifice bunt and a pinch-hit infield single by Travis Shaw moved him to third base. After the Red Sox put runners at second and third with one out in the bottom of the ninth, a sacrifice fly by Kiké Hernández pushed across the series-winning run.Composite line score

The Astros won the season series with the White Sox, 5–2. This was the second postseason meeting between the franchises. Their previous postseason meeting was in the 2005 World Series, when the Astros were members of the National League, won by the White Sox in a four-game sweep.This was the second time for a prior World Series matchup to occur in either a Wild Card Game, Division Series or League Championship Series. The first such instance was in the 2011 National League Championship Series, during which the St. Louis Cardinals defeated the Milwaukee Brewers, 4–2, in a rematch of the 1982 World Series. This was the first time in franchise history the White Sox have appeared in the postseason in consecutive seasons, while this was the fifth straight postseason appearance for the Astros.
As of the 2021 postseason, Tony La Russa and Dusty Baker were the oldest managers in MLB. Including their 2021 postseason appearances, La Russa and Joe Torre were tied for the second-most playoff appearances as managers, with 15, while Baker was next on the list with 11. The only prior time Baker's and La Russa's teams faced each other in the postseason was in the 2002 National League Championship Series, when Baker's Giants defeated La Russa's Cardinals in five games.
Despite their lone postseason match-up, Baker and La Russa share a long history, having known each other for 50 years. As La Russa was winding down his playing career, he spent a season in Atlanta where a young Baker was just starting his playing career with the 1971 Braves. The two men also spent a season together on the 1986 Athletics, when Baker was ending his playing career and La Russa was on his second managerial job. As managers, Baker and La Russa both competed in the NL Central from 2003 to 2006 and again from 2008 to 2011. In 2014, when each manager was out of the game for a time, they made peace with each other upon conversations spent with Dave Stewart, who worked for both managers as a player, manager, and general manager.
