The 2005 World Series was the championship series of Major League Baseball's (MLB) 2005 season. The 101st edition of the World Series, it was a best-of-seven playoff between the American League (AL) champion Chicago White Sox and the National League (NL) champion Houston Astros. The White Sox swept the Astros in four games, winning their third World Series championship and their first in 88 years. The series was played between October 22–26, 2005.

Home field advantage was awarded to Chicago by virtue of the AL's 7–5 victory over the NL in the 2005 MLB All-Star Game. The Astros were attempting to become the fourth consecutive wild card team to win the Series, following the Anaheim Angels (2002), Florida Marlins (2003) and Boston Red Sox (2004). Both teams were attempting to overcome decades of disappointment, with a combined 132 years between the two teams without a title. The Astros were making their first Series appearance in 44 years of play, while the White Sox had waited exactly twice as long for a title, having last won the Series in 1917, and had not been in the Series since 1959, three years before the Astros' inaugural season.

2005 World Series

Background

Chicago White Sox

The Chicago White Sox finished the regular season with the best record in the American League at 99–63. The 2005 White Sox led their division wire to wire and only losing 1 game in the postseason. After starting the season on a tear, the White Sox began to fade in August, when a game lead (for the AL Central division title) fell all the way to at one point. However, the Sox were able to hold off the Cleveland Indians to win the American League Central Division by six games, sweeping Cleveland in three games on the season's final weekend. In the Division Series, the top-seeded White Sox swept the defending champion Boston Red Sox. The League Championship Series began with the second-seeded Los Angeles Angels of Anaheim winning Game 1, but a controversial uncaught third strike in Game 2 helped the Sox start a run and win Games 2–5, all on complete games pitched by starters Mark Buehrle, Jon Garland, Freddy García, and José Contreras, clinching their first American League pennant in 46 years. In game 3 of the ALDS Orlando Hernandez came in with the bases loaded due to Damaso Marte loading the bases with a single and back to back walks. El Duque came in and induced 2 pop outs and a strike out to end the inning and persevere the lead.

2005 World Series

Manager Ozzie Guillén then led the White Sox to a World Series victory, their first in 88 years. Slugger Frank Thomas was not on the post-season roster because he was injured, but the team honored his perennial contributions to the franchise during Game 1 of the Division Series against the Boston Red Sox when he was chosen to throw out the ceremonial first pitch. "What a feeling," Thomas said. "Standing all around the place. People really cheering me. I had tears in my eyes. To really know the fans cared that much about me – it was a great feeling. One of my proudest moments in the game."

2005 World Series

The White Sox completed the 2005 postseason with an 11-1 record. The Sox also won the last 5 regular season games and thus closed out the 2005 campaign winning 16 of the last 17 games played, a record finish unmatched in all of MLB history.

Houston Astros

The Houston Astros won the Wild Card for the second straight year, once again clinching it on the final day of the season. The Astros embarked on a memorable Division Series rematch against the Atlanta Braves, who were the second seed in the NL. With the Astros in the lead two games to one, the teams played an 18-inning marathon in Game 4, which was the longest (in both time and innings played) postseason game in history. In this game, Roger Clemens made only the second relief appearance of his career, and the first in postseason play. Chris Burke's walk-off home run ended the game in the bottom of the 18th. For the second straight year, the Astros played the top-seeded St. Louis Cardinals in the League Championship Series. Like the White Sox, the Astros dropped Game 1, but were able to regroup and win Games 2–4. With the Astros on the verge of clinching their first ever National League pennant in Game 5, Albert Pujols hit a mammoth three-run home run off Brad Lidge in the top of the ninth inning to take the lead, and subsequently stave off elimination. However, behind NLCS MVP Roy Oswalt, the Astros were able to defeat the Cards 5–1 in Game 6 and earned a trip to the World Series. With the win, this was the Astros' first World Series appearance in franchise history, and the last game played in Busch Stadium II, as it was demolished months after the game and the Cardinals moved to Busch Stadium III the next season.
