Indians 3, Diamondbacks 2 (1st): Zach Walters homered with one out in the bottom of the ninth inning as Cleveland prevailed in the first game of a doubleheader.

Walters, who was acquired from Washington prior to last month's trade deadline, belted a 1-2 fastball from Randall Delgado (1-3) over the wall in right - his second hit of the game - in his second contest with the Indians. Cody Allen (4-2) allowed a two-out walk and struck out two in the ninth to earn the victory.

Trevor Bauer, the No. 3 pick in the 2011 draft by Arizona, faced his former team for the first time and struck out nine while yielding two runs and four hits in a career-high eight innings. Vidal Nuno remained winless in seven starts with the Diamondbacks after allowing two runs and six hits while striking out six in 5 2/3 innings.

Michael Brantley delivered a two-run single as Cleveland fell to 5 1/2 games behind first-place Kansas City in the American League Central and five back in the wild card race after dropping the nightcap 1-0 in 12 innings. Aaron Hill drove in a run for Arizona, which is 4-7 in August as it began a 10-game road trip with the doubleheader.

The Diamondbacks broke through in the sixth when Jake Lamb led off with a walk and scored on Jordan Pacheco's double play. The Indians took a 2-1 lead in the bottom half as Brantley delivered a two-out single off second baseman Hill's glove before the Diamondbacks got even in the seventh on Hill's RBI groundout.
