Helton powers Rockies past D-backs, 4-3

Posted: Updated:

DENVER (AP) -- Todd Helton hit a go-ahead homer in the eighth inning and drove in a run with his 500th career double, lifting the Colorado Rockies to a 4-3 win over the Arizona Diamondbacks on Wednesday.

Carlos Gonzalez, who's been mired in a slump that's cost him playing time, had two doubles and scored twice as the NL wild-card leading Rockies won two of three against the Diamondbacks.

Juan Rincon (2-1) pitched a perfect eighth and Huston Street closed out the ninth for his 24th save in 25 chances. He struck Josh Whitesell looking to end the game.

The afternoon belonged to Helton, who put the Rockies ahead for good with a solo shot to right-center off Arizona reliever Scott Schoeneweis (1-2).
