SAN DIEGO — Rookie Jedd Gyorko hit a go-ahead homer leading off the eighth inning to give the San Diego Padres a 2-1 win over the Colorado Rockies on Saturday night.
Gyorko's shot off Matt Belisle (5-6) came right after the Rockies tied the game at 1 in the eighth inning on a San Diego error.
Gyorko's 17th home run just barely cleared the right field wall as it hit the top padding and avoided the leaping attempt of right fielder Michael Cuddyer.
Luke Gregerson (6-7) got the win and Huston Street picked up his 28th save by getting the final three outs.
The Rockies spoiled a strong outing by Padres starter Tyson Ross, who allowed just three hits in seven innings.
Charlie Blackmon led off the Colorado eighth against Gregerson with a single and was forced out by pinch hitter Ryan Wheeler. Charlie Culberson came in to pinch run and stole second with two outs.
DJ LeMahieu then hit a sharp single to left field. Chris Denorfia fired a one-bounce throw to catcher Nick Hundley, who went to make the tag on Culberson who was going head first.
Hundley applied the tag in time, but Culberson's slide ripped the glove off Hundley and the ball came out.
Alexi Amarista drove in San Diego's first run with a bases-loaded, infield single in the first inning.
Colorado's Todd Helton hit his 585th double in the seventh inning, tying him for 16th place on the all time list with Rafael Palmeiro.
The Rockies had just two base runners reach second base against Ross. The closest Colorado came to scoring on Ross came after Helton doubled to lead off the seventh.
With one out, Yorvit Torrealba hit a low line drive to right field that Will Venable went for and caught. Venable then doubled Helton off second.
Colorado's Tyler Chatwood allowed one run and five hits in his six innings.
Denorfia and Gyorko had consecutive one-out singles in the San Diego first.
After Jesus Guzman drew a walk with two outs, Amarista drove in a run when his ground ball deflected off the Chatwood's glove for an infield single.
Chatwood was making his second start since coming off the DL last Sunday. In his first start back, the right-hander lasted just two innings against Cincinnati when he took a line drive off his right thumb and had to leave the game.
