Jason Bay made a smashing debut with Boston by tripling and scoring the winning run in the 12th inning Friday night as the Red Sox began the post-Manny Ramirez era with a 2-1 win over the Oakland Athletics.Bay was obtained from Pittsburgh on Thursday in the deal that sent the slugging Ramirez to the Los Angeles Dodgers. The former Pirate took Ramirez's spot - in left field and with clutch hitting.

He had failed to put the ball in play in his first five at bats - two walks, a hit by pitch and two strikeouts - before he came up with two outs in the 12th against Alan Embree (1-4). He hit the ball high to left field with the crowd hoping for a game-winning homer.

But it hit the wall and Bay slid into third with a triple. J.D. Drew then was walked intentionally.

Jed Lowrie, who had left the bases loaded in the 10th, then hit a soft bouncer past the mound. Shortstop Bobby Crosby rushed in, grabbed it and threw to first. But Lowrie beat the throw, scoring Bay with the winning run.
