Jason Giambi’s pinch-hit, walk off home run in the bottom of the ninth, broke a 5-5 tie and lifted the Colorado Rockies (12-12) over the Los Angeles Dodgers (17-8) 8-5 yesterday afternoon in Denver. Giambi’s blast came after the Dodgers had tied the game in the top of the ninth. The Rockies have today off, before hosting the Atlanta Braves (15-10) tomorrow night at 6:40 at Coors Field (TV: Root Sports).

The victory over the National League West-leading Dodgers (17-8) pulled the Rockies (12-12) to .500, gave the Rockies 2-of-3 in the series, and no doubt lifted a club that isn’t guaranteed victory no matter how many dramatic moments it provides.

Giambi’s homer, on a day when Carlos Gonzalez went deep twice and rookie Wilin Rosario also homered off Dodgers lefty stalwart Clayton Kershaw, certainly prevented the current nine-game homestand — 3-3 going into a weekend series with the Braves — from becoming a study in frustration.

Official: Wednesday’s Box Score.

Rockies left-handed rookie starter Drew Pomeranz went a career-high 6 2/3 innings and gave up one run on four hits, with five walks and four strikeouts. Kershaw allowed five runs on seven hits — including the three homers — in 7 1/3 innings.
