White Sox 8, Indians 1: Adam Dunn belted a two-run homer and Jake Peavy tossed seven solid innings as visiting Chicago salvaged a split of a four-game series with its American League Central rival.

Alejandro De Aza ripped a two-run single and A.J. Pierzynski and Alexei Ramirez also drove in a run apiece to highlight a six-run fourth inning.

The White Sox improved to 10-8 on the road and moved to within three games of the first-place Indians.

After a 64-minute rain delay halted the start of the game, Dunn put Chicago on top in the first inning by depositing a slider from Jeanmar Gomez (2-2) into the seats in right-center field. Dunn has 10 homers this season – one less than he had all of last season.

The six-run fourth inning provided quite the cushion for Peavy (4-1), who allowed one run on seven hits and struck out five.

Gomez yielded eight runs on nine hits in 6 2/3 innings to take the loss as the Indians dropped their second straight.

GAME NOTEBOOK: White Sox closer Chris Sale will undergo an MRI exam on his left elbow in Chicago on Thursday. "It's more for a peace-of-mind thing," Sale said.
