DENVER (AP) -- Micah Owings pitched five effective innings for his first win in more than a year and Miguel Montero hit a three-run homer, helping the Arizona Diamondbacks beat the slumping Colorado Rockies 6-3 on Thursday night.

Owings (1-0) bottled up the Rockies' struggling offense, allowing just four hits and striking out three. The only run he surrendered was an RBI single by Troy Tulowitzki in the fourth.

The right-hander earned his first win since last May, when he was a member of the Cincinnati Reds. This was Owings' second start of the season for the Diamondbacks in his second stint back with the squad.

Clayton Mortensen (1-2) took the loss.
