|2006 World Series|
The 2006 American League Championship Series (ALCS) was the second round of the 2006 American League playoffs; it began on October 10 and ended on October 14. The Detroit Tigers defeated the Oakland Athletics four games to none to advance to the 2006 World Series, and became the fourth AL team to win ten pennants, joining the New York Yankees (39), Athletics (15) and Boston Red Sox (11). Magglio Ordóñez's game-winning walk-off home run in the bottom of the ninth inning of Game 4 sealed the pennant for the Tigers. This ALCS marked the fifth different AL pennant winner in as many years (2006 Tigers, 2005 White Sox, 2004 Red Sox, 2003 Yankees, and 2002 Angels).
The Athletics had defeated the Minnesota Twins, three games to none, in AL Division Series, and the Tigers had defeated the Yankees, three games to one. The Tigers faced the National League champion St. Louis Cardinals in the World Series, but fell to them, four games to one. Oakland had home-field advantage (despite Detroit having a better record) because Oakland was a division champion, but they effectively lost the advantage by losing Games 1 and 2 at home. Detroit hosted Games 3 and 4.
The Athletics were seeking their first AL pennant since 1990, while the Tigers captured the league title for the first time since their 1984 World Series championship year. The series was a rematch of the 1972 American League Championship Series, in which Oakland defeated Detroit in five games (then a best-of-five series). Detroit manager Jim Leyland, who led the Florida Marlins to the 1997 World Series title, became the seventh manager in history to win pennants in both leagues.

Game summaries 
Game 1 
|WP: Nate Robertson (1–0) LP: Barry Zito (0–1)
DET: Brandon Inge (1), Iván Rodríguez (1)
Oakland was 0-for-13 with runners in scoring position, while Detroit turned four double plays (both are LCS records). Tigers first baseman Sean Casey left the game in the bottom of the sixth inning due to an apparent leg injury.
Game 2 
|WP: Justin Verlander (1–0) LP: Esteban Loaiza (0–1) Sv: Todd Jones (1)
DET: Alexis Gomez (1), Curtis Granderson (1)
OAK: Milton Bradley 2 (2), Eric Chavez (1)
Detroit used a four-run fourth inning to erase a 3–1 deficit to take a 2–0 lead in the series. Detroit survived two home runs by Milton Bradley and a bases-loaded jam in the ninth inning to escape with a win. Since the ALCS has been increased to a seven-game series, no team has come back to win the series after losing the first two games at home.
Game 3 
|WP: Kenny Rogers (1–0) LP: Rich Harden (0–1) Sv: Todd Jones (2)
DET: Craig Monroe (1)
Oakland infielder Mark Kiger, who was called up from the minors for the ALCS following an injury to Mark Ellis, entered the game in the eighth inning as a defensive replacement for second baseman D'Angelo Jiménez, thereby becoming the first player in modern baseball history to make his major-league debut in a postseason game. Kenny Rogers also continued to dominate, not allowing the A's to score once for his second victory in the postseason. Todd Jones picked up his second save.
Game 4 
|WP: Wilfredo Ledezma (1–0) LP: Huston Street (0–1)
OAK: Jay Payton (1)
DET: Magglio Ordóñez 2 (2)
In Game 4, the A's took a 2–0 lead in the first on RBI doubles from Eric Chavez and Milton Bradley. Jay Payton homered in the fourth to make it 3–0. In the fifth, however, the Tigers rallied. Curtis Granderson and Craig Monroe both hit RBI doubles to make it 3–2 Oakland, and Magglio Ordóñez homered in the sixth to tie the game at three. In the bottom of the ninth with two outs, Ordóñez launched a three-run walk-off home run off Huston Street to win the game and advance the Tigers to the 2006 World Series. Ordóñez's blast was the first pennant-winning home run since Aaron Boone's in Game 7 of the 2003 ALCS.
