The rivals combined for six AL pennants and four world championships in the `00s, and their first postseason confrontation of the decade lived up to the hype. Upstaging Roger Clemens, Pedro Martinez got the Red Sox within five outs of the pennant, but Boston manager Grady Little was too slow with his hook and the Yankees, buoyed by a pair of Jason Giambi homers and three scoreless innings of relief from Mike Mussina, rallied to tie it in the bottom of the eighth. Mariano Rivera pitched three scoreless innings of his own before Aaron Boone finally won the pennant with a walk-off home run off Tim Wakefield on the first pitch of the bottom of the 11th.
