Game 2

Game 2 started just after 4 pm EDT, and the sun was difficult in the outfield for the first three innings. The Yankees' offense was again dead silent, this time against Mariner starter John Halama and reliever José Paniagua. In the first, New York loaded the bases (without a hit) and no outs, but could not score. Bernie Williams' ground ball went just inches and M's catcher Dan Wilson grabbed it, stepped on home, and threw to first for the double play; Tino Martinez then grounded out to second. In the top of the second, Seattle threatened with a leadoff walk by Edgar Martínez followed by a lunging single to center by John Olerud. Al Martin flew out to deep right center and the two advanced. David Bell lined the ball back to Orlando Hernández, who doubled up Olerud at second to end the inning.

Hernández pitched eight innings and gave up just one run, a Stan Javier single in the third that scored Mike Cameron, who had walked with two outs and stole second, after nearly being picked off at first. Hernández gave up six hits, but was set to get the loss until the Yankees' offense exploded in the eighth against Arthur Rhodes and José Mesa. David Justice led off with a double and scored on a single by Williams to tie the game, New York's first run in 21 innings. Back-to-back singles by Martinez and Jorge Posada then gave New York a 2–1 lead. Paul O'Neill then hit a sacrifice fly to score another. Mesa replaced Rhodes for Seattle and gave up a single to Luis Sojo. Posada was caught diving back to third for the second out on a safety squeeze; José Vizcaíno then doubled to left center to score Sojo from first to make it 4–1 Yankees. Vizcaíno went to third on a passed ball, scored on a Chuck Knoblauch single up the middle, and Derek Jeter sliced a homer to right to make it 7–1. Up again, Justice fouled off several and flew out to center to end the lengthy inning. Closer Mariano Rivera pitched a scoreless ninth: Olerud sliced a ground-rule double to lead off, but three ground balls ended the game; the series was tied at 1–1 and headed to Seattle.
