A.J. Pierzynski's sac-fly RBI in the top of the ninth was the difference as the White Sox nipped the Rockies, 3-2, on Wednesday night at Coors Field. Pierzynski also doubled in a run during a two-run fourth for Chicago, which stopped a two-game skid with the win. Mark Buehrle [[ BURR-lee ]] lasted seven innings in a no-decision. Brian Bruney picked up his first win. Sergio Santos tossed a perfect ninth to notch his 16th save. Jason Giambi and Ty Wigginton hit solo homers for Colorado, which was a 3-2 winner in the opener of the three-game set on Tuesday. Ubaldo Jimenez also went seven innings in a no-decision. Huston Street was saddled with his second loss. Jake Peavy will toe the rubber opposite Aaron Cook in this afternoon's series finale.
