Cleveland, OH (Sports Network) - Jason Giambi turned a bitter Progressive Field crowd into a raucous mad house with a game-winning two-run homer in the ninth inning to propel the surging Cleveland Indians to a 5-4 victory over the Chicago White Sox.

A chorus of boos rained down on Indians closer Chris Perez after he yielded a tying solo homer to Dayan Viciedo and a go-ahead shot to Alejandro De Aza in the top of the ninth.

Those home runs were an afterthought after Michael Brantley singled with one away to bring the go-ahead run to the plate in the form of Giambi, who crushed a pinch-hit homer off Addison Reed (5-4) deep into the right-field seats.

The Indians' fifth straight win -- and 13th in a row over the White Sox -- kept them in control of the second AL wild card spot.
