CHICAGO, Sept. 29 (UPI) -- The Chicago White Sox scored a run in the bottom of the ninth Tuesday on a pinch-hit RBI single by Dayan Viciedo to upend the Boston Red Sox 5-4.
The Red Sox were officially eliminated from the pennant race earlier in the evening when the New York Yankees beat Toronto.
Chicago scored single runs in the seventh, eighth and ninth innings to grab their fifth win in their last six tries.
Carlos Quentin had a two-run homer for the White Sox and Manny Ramirez had a hit and two walks.
J.D. Drew and David Ortiz hit solo home runs for the Red Sox, who led 3-0 after three innings.
After Ortiz's 32nd homer of the year staked Boston to a 4-2 lead in the sixth, the White Sox began a slow-motion rally. Quentin drove in a run in the seventh with a single and Chicago tied the game 4-4 in the eighth on Paul Konerko's RBI double.
In the ninth, Pierre reached on an infield single, stole second and third and then raced home on a looper by Viciedo that dropped just of the reach of the diving Daniel Nava.
The rally handed the loss to Michael Bowden (0-1) the first of three Boston relievers who worked the ninth.
Chris Sale (2-1) was the winner in relief of Edwin Jackson.
