J.D. Martinez hit a three-run homer with two outs in the ninth inning, but the Twins rallied with two runs in the bottom of the frame for a wild 4-3 victory over the Tigers at Target Field.

The Giants secured a victory they desperately needed to regain their stride in their twin postseason races Tuesday night, outlasting the Arizona Diamondbacks, 2-1. Buster Posey homered to help support Jake Peavy’s resolute 7 2/3-inning effort that ended San Francisco’s three-game losing streak.

Manager Buck Showalter and his talented group of Orioles players believe in each other, and that’s the main reason Baltimore clinched its first American League East title since 1997 on Tuesday night.
