|2001 World Series|
The 2001 American League Championship Series (ALCS) was a rematch of the 2000 ALCS between the New York Yankees, who had come off a dramatic comeback against the Oakland Athletics in the Division Series after being down two games to zero, and the Seattle Mariners, who had won their Division Series against the Cleveland Indians in five games. The series had additional poignancy, coming immediately after downtown New York City was devastated by the events of September 11, 2001. (The series was played in late October due to Major League Baseball temporarily shutting down in the wake of the attacks).
Though the Mariners had won an American League record 116 regular season games, and had home field advantage, unlike the 2000 ALCS where the Yankees had home field advantage, the Yankees proved overpowering as they won the first two games in Seattle. The Mariners' manager, former Yankee player and manager Lou Piniella, guaranteed after Game 2 that the Mariners would win at least two of the next three games in New York to return the series to Seattle. However, he turned out to be wrong as the Yankees closed out the series in New York, beating the Mariners four games to one. The series ended with a 12–3 Yankees victory in Game 5.

 Game summaries
 Game 1
|WP: Andy Pettitte (1–0) LP: Aaron Sele (0–1) Sv: Mariano Rivera (1)
NYY: Paul O'Neill (1)
Game 1's starting date was the latest ever for a League Championship series. The Yankees took a 1–0 lead on a Chuck Knoblauch single that scored Jorge Posada in the second, then increased it to 3–0 on a Paul O'Neill home run in the fourth. The Mariners got on the board on a John Olerud groundout that scored Edgar Martínez in the fifth. The score remained 3–1 until the ninth when the Yankees increased their lead to 4–1 on a David Justice single that scored Alfonso Soriano. The Mariners got that run back in the bottom of the inning when Mariano Rivera threw a wild pitch to Bret Boone that scored Ichiro Suzuki, but Rivera retired Boone and the next batter, Edgar Martínez, to end the game.
 Game 2
|WP: Mike Mussina (1–0) LP: Freddy García (0–1) Sv: Mariano Rivera (2)
SEA: Stan Javier (1)
In Game 2, the Yankees took a 2–0 lead in the second against Freddy García on a Scott Brosius double that scored Tino Martinez and Jorge Posada. Brosius would then score on a Chuck Knoblauch single two batters later to make it 3–0 Yankees. The Mariners responded in the fourth on a two-run home run from Stan Javier off of Mike Mussina to make it a one-run game. However, neither team would score afterwards and the Yankees took a 2–0 series lead heading to New York City.

However, they would not be able to score again until the eighth on a David Justice single. Orlando Hernández pitched four shutout innings before giving up a game-tying two-run single to Bret Boone in the fifth. The Mariners then scored seven runs in the sixth capped by home runs by Boone and John Olerud to take a 9–2 lead. They would not look back, scoring five more runs in the next three innings, including a Jay Buhner home run in the ninth, off of three Yankee relievers to cruise to a 14–3 win and guarantee a Game 5.

Mariano Rivera pitched a scoreless ninth and the Yankees won the game 3–1 in the bottom of the inning on an Alfonso Soriano two-run home run off Kazuhiro Sasaki to take a 3–1 series lead.
 Game 5
|WP: Andy Pettitte (2–0) LP: Aaron Sele (0–2)

Paul O'Neill homered in the fourth to put the Yankees on top 5–0. They would break the game open with four runs in the sixth, making the score 9–0. The Mariners got their only three runs of the game in the seventh on back-to-back singles by Bell and Ichiro Suzuki off Andy Pettitte. In the bottom of the eighth, Tino Martinez hit a three-run home run as the Yankees cruised to a 12–3 win and advance to the World Series for the fourth straight year.
