Kazuhiro Sasaki
Starting pitchers Paul Abbott and Roger Clemens both lasted only five innings, but Game 4 remained scoreless until the top of the eighth. Seattle's Bret Boone hit a solo home run off reliever Ramiro Mendoza for the game's first tally, but the Yankees responded in the bottom of the inning with a Bernie Williams home run to right on a full count off Arthur Rhodes to tie the game. Mariano Rivera retired the side in order in the ninth, and Mariners closer Kazuhiro Sasaki got the first out, then allowed an infield single by Scott Brosius. The next hitter was rookie Alfonso Soriano, whose walk-off home run to right-center won the game, 3–1.
