DENVER (AP) — Nick Evans and Chris Owings hit back-to-back homers, rookie Chase Anderson won his fourth straight start and the Arizona Diamondbacks beat the slumping Colorado Rockies 4-2 on Tuesday night.
Evans' solo shot in the fourth was his first homer since Sept. 3, 2011, when he was with the New York Mets. Four pitches later, Owings hit another off Jorge De La Rosa (6-4). Owings also added an RBI double and finished a single shy of the cycle.
Anderson (4-0) didn't overpower the Rockies so much as keep them guessing, throwing six effective innings in his longest outing since he was recalled from Triple-A Reno on May 6. He becomes the fifth rookie since 1998 to win his opening four starts.
Anderson allowed four hits and one run — a homer by D.J. LeMahieu — to help the Diamondbacks stop a three-game skid.
De La Rosa settled down after a shaky start, giving up three runs in seven innings. The hard-throwing lefty didn't have a strikeout for the first time this season, and his six-game winning streak came to an end.
The Rockies opened a 10-game homestand with their fifth straight loss. The best-hitting team in baseball just finished a dismal road swing in which it went 2-7 and averaged less than three runs a game.
Colorado struggled against Anderson, who mixed a fastball that barely crept into the 90s with a sharp curve and a changeup. Anderson also benefited from an overturned call at the plate in the second that kept the game scoreless.
Wilin Rosario was ruled safe by umpire Jerry Layne after sliding past the tag of catcher Miguel Montero. As Montero protested, manager Kirk Gibson trotted out of the dugout to challenge the play. The call was reversed when replays showed Montero tagged Rosario on the back before touching home.
The Diamondbacks took a 3-0 lead in the fourth on homers from Evans and Owings, along with an RBI groundout by Gerardo Parra. Evans was just recalled last week from Reno and his homer was his first hit of the season.
That was more than enough for Anderson, who was taken out for a reliever in the seventh. Addison Reed pitched a wobbly ninth — surrendering a solo homer to Troy Tulowitzki — but struck out LeMahieu looking for his 15th save in 17 chances.
De La Rosa worked his way out of several early messes, including one in the second when Justin Morneau threw out Owings at home on a sharp grounder.
The sun created some awkward shadows on the field in the first and led the Rockies to run themselves out of the inning. Soon after Charlie Blackmon walked, Morneau sent a liner up the middle that Blackmon, looking toward the sun, figured a diving Owings caught. Blackmon retreated back to first as the ball rolled into center field. Ender Inciarte tossed it to second base for a less-than-routine 8-4 putout.
