With a 10-inning, 6-4 loss to the Chicago White Sox on Thursday afternoon, the Colorado Rockies are just 1-5 at Coors Field against them. Former Colorado Rockies center fielder Juan Pierre delivered the go-ahead two-run single in the top of the 10th with Clayton Mortensen on the mound.
Mortensen's troubles began when Gordon Beckham put down a bunt, which he was unable to come up with. This loaded the bases, and Paul Konerko hit into a fielder's choice, the out coming at home plate. Pierre came to the plate and deposited a single into deep right field to score two runs.
In the bottom of the inning, Seth Smith and Ty Wigginton struck out swinging and Charlie Blackmon grounded out to second base to end the game.
The Rockies were put in that position because Matt Lindstrom allowed a Gordon Beckham RBI single and a Juan Pierre sac fly in the bottom of the eighth, blowing a 4-2 lead. Aaron Cook (4.66 ERA) allowed one run on five hits and four walks over six innings. Rafael Betancourt allowed a leadoff homer by Beckham in the seventh inning.
White Sox starter Jake Peavy allowed four runs in six innings, three allowed on Troy Tulowitzki's three-run home run (15) in the bottom of the first inning. Matt Pagnozzi drove the other run in on a single in the sixth inning. Four White Sox relievers held the Rockies to two hits over the final four innings.
The Rockies (39-42, 20-21 home) host the Kansas City Royals on Friday.
