The 2005 Boston Red Sox season was the 105th season in the franchise's Major League Baseball history. The Red Sox finished second in the American League East with a record of 95–67, the same record as the New York Yankees. The Yankees were deemed the division winner, due to their 10–9 head-to-head record against the Red Sox during the regular season. The Red Sox qualified for the postseason as the AL wild card, but were swept by the American League Central champion Chicago White Sox in the ALDS. On offense, the Red Sox led Major League Baseball in runs scored (910), hits (1,579), doubles (339), RBI (863), walks (653), batting average (.281), OBP (.357), OPS (.811) and sacrifice flies (63). Red Sox pitchers hit opposing batters with 89 pitches, the most by any major league pitching staff in 2005.

Offseason

The Red Sox made a few notable offseason moves coming off their 2004 World Series championship. The team brought back Jason Varitek by re-signing the veteran catcher to a 4-year $40 million deal. Outfielder Dave Roberts – who played a key role as a base stealer during the 2004 postseason – was traded to the Padres in exchange for shortstop Ramon Vazquez and left fielder Jay Payton. Management sought to fill the void left by Orlando Cabrera and Pokey Reese at shortstop by signing free agent Édgar Rentería to a 4-year $40 million year with a 5th year option. The move sat well with fans because Rentería was coming off a very successful 2004 campaign with the St. Louis Cardinals. Rentería hit .287 with 10 home runs and 72 RBI in 2004. The Red Sox front office looked to bolster their starting pitching by signing two veteran pitchers. The need for starting pitching was a point of emphasize due to the departure of Pedro Martínez to the New York Mets after 7 years in a Red Sox uniform. The first pitcher signed was former Padres starter David Wells. Wells was coming off a surprising 2004 season with the Padres in which he posted a 3.73 ERA over 195 innings pitched at the age of 41. The second pitcher signed was former Cubs starter Matt Clement. Clement was coming off a season in which he posted a respectable 3.68 ERA over 181 innings pitched.

ALDS

The Chicago White Sox swept the Red Sox in the American League Division Series. The White Sox went on to win the World Series that year against the Houston Astros. The Red Sox entered the 2005 postseason as a wild card team even though they had the same regular season record as their division rival, the New York Yankees because they lost the regular season head-to-head matchups 10–9. A crucial moment of the series came in Game 2 when Red Sox second baseman Tony Graffanino made a crucial error that led to the White Sox scoring three unearned runs in the fifth inning. A slow groundball hit to the right side of the infield was able to get past Graffanino and a key double play was not turned. Later in the inning, White Sox second baseman Tadahito Iguchi hit a three-run home run to give the White Sox a one-run lead. Red Sox pitcher David Wells was pitching well in the game until the error. The error is viewed by many fans as having the Red Sox lose Game 2 and eventually the American League Division Series. Red Sox ace Curt Schilling did not start a game in the American League Division Series after pitching in the last game of the season against the Yankees.
