The Tigers were playing the game with a victory hangover as the team clinched the AL Central title on Friday night with a 3-1 win. It is Detroit's first division crown since winning the AL East in 1987 and its first appearance in the playoffs since 2006 as a wild card.
Coco Crisp drove in two runs while Jemile Weeks had three hits and an RBI for the Athletics, who had lost three of four coming into the game. Gonzalez (14-12) gave up eight hits and two walks with four strikeouts to win his second straight start.
Don Kelly hit a two-run double while Jhonny Peralta drove in the other run for the Tigers, who fell to 13-3 in September. Rick Porcello (14-9) went seven innings and was tagged for three runs on nine hits to take the loss.
Detroit had men on base in each inning except for the second, but were unable to put a run across until the sixth when Peralta lofted a sacrifice fly that scored Magglio Ordonez to make it a 3-1 game.
Weeks and Crisp added RBI singles in the eighth while Kelly nailed a pinch- hit, two-run double in the ninth to make it a two-run game and put the tying run at the plate with one out.
Oakland has won five of the nine games with Detroit this season...Porcello had won his previous three decisions. He fell to 2-4 in seven starts against the Athletics...Gonzalez is now 1-3 in five starts against Detroit.
