Duncan, who was pinch-hitting, and Cabrera both had two-run singles during the eighth to put Cleveland ahead 7-2. Duncan had a bases-loaded drive off J.P. Howell that hit the left-field wall, but he was held to a single because it looked like outfielder Sam Fuld might catch the ball.

James Shields (5-3) took the loss.

Rivera (1-1) made career appearance No. 1,001 in the 12th inning and gave up a one-out single by Justin Smoak and a double by Jack Cust. Rodriguez replaced Smoak as a pinch-runner at third, and after an intention walk to load the bases, Kennedy dumped an pitch in front of the center fielder to score Rodriguez.
David Pauley (4-0) worked two innings of relief to get the victory.
