DENVER (AP) - Todd Helton hit a two-run homer off closer J.J. Putz in the bottom of the ninth inning and the Colorado Rockies rallied for an 8-7 win over the Arizona Diamondbacks on a rain-soaked Saturday night.
With two outs, Helton belted his first homer of the season down the right-field line and the towering shot stayed just fair. He raised his hands in the air as he rounded the bases and was mobbed by teammates at home plate.
Tyler Chatwood (1-0) pitched two innings and gave up a run to earn the win in relief.
The Diamondbacks were trailing 5-1 when the game was halted by a relentless downpour after four innings. But the 71-minute break energized their bats and they came out of the clubhouse swinging.
