CLEVELAND -- Shelley Duncan's RBI double in the eighth inning gave the Cleveland Indians a soggy 3-2 win over the Chicago White Sox on Monday night and a sweep of their day-night doubleheader.
Duncan ripped a pitch from left-hander Matt Thornton (1-2) into the left-field corner, scoring Asdrubal Cabrera.
The first-place Indians won the opener 8-6.
The White Sox have lost six of seven.
Cleveland's Josh Tomlin allowed five hits in 7-1 3 innings -- most of the final three in a steady downpour. He struck out a career-high eight, allowed two walks and maintained his control despite slick, slippery conditions on the mound.
Joe Smith (2-1) gave up a game-tying single after a lengthy rain delay, but got two outs and was credited with the win after Duncan's single.
Tony Sipp worked the ninth for his first save.
