PITTSBURGH (AP) - Jordy Mercer doubled home Neil Walker with one out in the bottom of the 11th inning to lift the Pittsburgh Pirates to a 3-2 victory over the Colorado Rockies on Saturday night.
Walker led off the inning with a single against Colorado's Chad Bettis (0-2), moved to second on a sacrifice bunt, and scored one batter later when Mercer hit a drive deep into the gap in left-center.
Jared Hughes (5-2) earned the win after escaping a two-on, one-out jam in the 11th by snagging a line drive from Charlie Blackmon and turning it into a double play.
Walker went 3 for 5 with two runs scored for the Pirates.
Carlos Gonzalez hit a two-run homer for the Rockies, who lost All-Star shortstop Troy Tulowitzki in the fourth inning to a left thigh cramp.
