The 2021 Boston Red Sox season was the 121st season in the team's history, and their 110th season at Fenway Park. The team entered the offseason conducting a managerial search, after declining to bring back Ron Roenicke from the shortened 2020 season. ^[2] On November 6, 2020, the team re-hired Alex Cora as manager; Cora had skippered the Red Sox in 2018 and 2019, then sat out 2020 serving a one-year suspension for his role in the Houston Astros sign stealing scandal in 2017. ^[3]

This was the Red Sox' first season since 2019 with fans at Fenway Park, with a limited capacity of approximately 4,500 to start the season due to the ongoing COVID-19 pandemic. ^[4] The capacity was increased to approximately 9,400 for games after May 10. ^[5] Fenway returned to full capacity starting May 29, ^[6] with an announced attendance of 25,089 at that day's game. ^[7] The first home sellout of the season was the June 25 game against the New York Yankees, with an announced attendance of 36,869. ^[8]

On June 4–6, the Red Sox swept a three-game series against the rival Yankees at Yankee Stadium for the first time since June 2011. ^[9] On June 13, the Toronto Blue Jays set a single-game record for home runs by a visiting team at Fenway Park, with eight. ^[10] In early July, the Red Sox led MLB with five players selected to the All-Star Game. ^[11] Beginning in late August, the team had a spate of positive COVID-19 testing, resulting in more than 10 players being placed on the COVID-related injured list. ^{[12] [13]}

The Red Sox finished the regular season with a 92–70 record and qualified for the postseason as the fourth seed in the American League (AL), ^[14] defeating the fifth-seed Yankees in the AL Wild Card Game at Fenway Park on October 5. ^[15] They then defeated the Tampa Bay Rays in the AL Division Series, 3–1 games. ^[16] The Red Sox lost to the Houston Astros in the best-of-seven AL Championship Series in six games. ^[17]

Offseason

The Red Sox entered the offseason with the manager position vacant, as prior to the team's final game of the 2020 season, the team announced that Ron Roenicke would not be retained. ^[2]

The Red Sox also entered the offseason with six guaranteed player contracts for 2021, totaling slightly more than $115 million: Chris Sale ($25.60 million), Xander Bogaerts ($20 million), J. D. Martinez ($19.375 million), Nathan Eovaldi ($16.88 million); Dustin Pedroia ($13.3 million), and Christian Vázquez ($4.52 million). ^[18]

Drew in 2007 ALCS Game 6. ^[150] García left with none out in the top of the second due to knee discomfort. ^[151] Rafael Devers hit a second grand slam in the top of the second, making the Red Sox the first team in postseason history to hit two grand slams in one game. ^[152] A fourth-inning homer by Kiké Hernández, his third of the series, made it 9–0. The Astros rallied with two outs in the bottom of the fourth for three runs, trimming Boston's lead to 9–3. Eovaldi left after 5+1⁄3 innings, relieved by Adam Ottavino. Yuli Gurriel and Jason Castro each hit solo home runs off of Darwinzon Hernández in the bottom of the ninth, making it 9–5, the final score. ^[153]

Eduardo Rodríguez earned the win in Game 3 in what would turn out to be his last start as a member of the Red Sox.

Boston won Game 3, 12–3, to take a 2–1 lead in the series. Eduardo Rodríguez started for Boston and José Urquidy started for Houston. The Red Sox sent 11 men to the plate in the bottom of the second, scoring six runs. Four of the runs came on a grand slam by Kyle Schwarber, the third by a Red Sox batter in two games. ^[154] Urquidy left with two outs in the second, having allowed six runs (five earned) on five hits and two walks while striking out one batter. Boston added three runs in the bottom of the third, including a two-run homer by Christian Arroyo, extending the Red Sox' lead to 9–0. Astros right fielder Kyle Tucker hit a three-run homer with two out in the top of the fourth, making it a 9–3 game. Boston made it 11–3 in the bottom of the sixth via a two-run homer by J. D. Martinez.

Game 4

Houston won Game 4, 9–2, powered by a seven-run ninth inning to even the series, 2–2. Nick Pivetta started for Boston and Zack Greinke started for Houston. The Astros took an early 1–0 lead via a solo home run by Alex Bregman with two outs in the top of the first. In the bottom of the first, Rafael Devers walked with two outs, then Xander Bogaerts homered to give the Red Sox a 2–1 lead. Greinke left with one out in the bottom of the second, having allowed two runs on one hit and three walks; he did not strike out a batter. Christian Arroyo hit a one-out triple in the bottom of the fourth, but the Red Sox were unable to score him. Bogaerts hit a one-out double in the bottom of the fifth and was also left stranded. Pivetta left after the fifth inning, having allowed one run on two hits and two walks; he struck out three. Jose Altuve tied the game, 2–2, with a home run off of Garrett Whitlock to lead off the eighth inning. Nate Eovaldi came in to pitch the top of the ninth, and Carlos Correa led off with a double over Hunter Renfroe in right field. With two outs, Jason Castro singled to drive in Correa and give the Astros a 3–2 lead. Houston was able to load the bases, and Boston brought in Martín Pérez. Michael Brantley hit his first pitch for a double that scored three runs, giving Houston a 6–2 lead. A single by Yordan Alvarez plated another run, making it 7–2. Correa, batting for the second time in the inning, hit a ball fielded by Pérez that was thrown away for an error, allowing another run to score, and a single by Kyle Tucker drove in the Astros' seventh and final run of the inning. ^[156] Houston closer Ryan Pressly came in to pitch the bottom of the ninth; he allowed two singles, but prevented Boston from scoring as Houston evened the series. ^[157]

Game 5

Houston won Game 5 by a 9–1 score, putting them a win away from the AL pennant, with the remaining game(s) of the series to be played in Houston. ^[158] Chris Sale started for the Red Sox and Framber Valdez started for the Astros. Houston took a 1–0 lead on a solo home run by Yordan Alvarez in the top of the second inning. ^[159] Valdez did not allow a Boston baserunner until the fifth inning.

Game 6

Luis García started for Houston and Nathan Eovaldi for Boston, a rematch of Game 2. The Astros took a 1–0 lead in the bottom of the first; with two outs, Alex Bregman singled then was driven in on a double by Yordan Alvarez that hit off the glove of Red Sox center fielder Kiké Hernández. In the bottom of the fourth, Houston had runners on second and third with no outs, but Eovaldi struck out the next two batters, intentionally walked Yuli Gurriel, and then struck out Chas McCormick to end the threat. Eovaldi left with one out in the bottom of the fifth, having allowed one run on five hits while striking out four; he was relieved by Josh Taylor. García held the Red Sox hitless through five innings; he left in the top of the sixth after allowing a two-out triple to Hernández. ^[162] García was relieved by Phil Maton, who ended the threat by getting Rafael Devers to pop out. Alvarez opened the bottom of the sixth with a triple off of Taylor near the right-field line. After Carlos Correa was hit by a pitch from Tanner Houck, Kyle Tucker grounded into a double play, scoring Alvarez and giving Houston a 2–0 lead. In the top of the seventh, Boston had runners at first and third with one out; Kendall Graveman struck out Travis Shaw and catcher Martín Maldonado threw out Alex Verdugo, who had been running on the pitch, at second base to end the inning. Alvarez collected his fourth hit of the game in the bottom of the eighth, singling to give the Astros runners at first and second with one out. After Correa grounded out, Tucker homered off of Adam Ottavino, extending Houston's lead to 5–0. Astros closer Ryan Pressly entered to pitch the top of the ninth. He retired the side in order, ^[163] as Houston advanced to the World Series. ^[164]

Entering the 2021 season, the Red Sox' farm system underwent multiple changes:

• The Worcester Red Sox succeeded the Pawtucket Red Sox as the Triple-A affiliate. ^[222]
• The Lowell Spinners were dropped as an affiliate, as part of a reduction of the total number of minor league teams affiliated with MLB. ^[36]
• The Greenville Drive and Salem Red Sox swapped relative classification levels, with Greenville moving from Single-A to High-A, and Salem moving from Class A-Advanced to Low-A. ^[223]

Notes

1. NESN also announced additional broadcast personnel: Mike Monaco for play-by-play, Jahmai Webster as sideline reporter, Tom Caron as studio host, and a rotation of studio personnel including former Red Sox players Lenny DiNardo, Jonathan Papelbon, Jim Rice, Mo Vaughn, Tim Wakefield, and Kevin Youkilis. ^[1]
2. Rafael Devers was originally credited with two RBIs during the 11th inning of the June 22 game; a later scoring change ruled that he reached base via an error, thus removing those two RBIs. ^[85]
3. Due to COVID-19 restrictions in Canada, the Toronto Blue Jays scheduled home games through the end of May at their spring training facility, TD Ballpark in Dunedin, Florida, ^[167] and home games for June and July at Sahlen Field, home ballpark of their Triple-A farm team in Buffalo, New York. ^[168]
