DENVER (AP) — Carlos Gonzalez homered twice and the Colorado Rockies became the first team to decipher Josh Collmenter’s tomahawk-throwing style, rallying past Arizona 12-4 Tuesday despite losing pitcher Jorge De La Rosa in the opener of the day-night doubleheader.

Colorado ended its three-game skid and stop the Diamondbacks’ six-game winning streak.

Greg Reynolds (2-0) picked up the victory. He was pressed into duty when De La Rosa, coming off his first career complete game, had to leave.

Collmenter (3-1), the Arizona rookie right-hander with the unusual straight overhand delivery, blanked Colorado for three innings to run his scoreless streak to 24 before he gave up solo homers to Gonzalez and Seth Smith in the fourth.
