A grieving Jhoulys Chacin could have skipped his latest start in the wake of his grandmother's death. He wanted a chance to pitch, though.

Chacin did his best to hold down Baltimore's big hitters, but eventually they broke through Sunday and carried the Orioles to a 7-2 victory over the Colorado Rockies.

Chris Davis went 4 for 5 with his major league-leading 45th home run, and Adam Jones had a two-run shot among his three hits for Baltimore.

Chacin (11-7) took the ball one day after his grandmother died. The right-hander, who entered with a 1.87 road ERA, gave up nine of Baltimore's 15 hits and three runs over 5 1-3 innings while striking out five.

"He fought his way through," Rockies manager Walt Weiss said of Chacin, who left with the score 3-2. "He was pretty emotional and pitching with a heavy heart, but he battled and he wanted to stay out there. He competed well, kept the game in check."

Colorado arrived in Baltimore having won five of six, but left stop one of three on a 10-game road swing with a loss. After taking the series opener, the Rockies dropped two straight in the first meeting between the teams since 2007.

Opportunities existed against starter Scott Feldman (3-3) and Baltimore's bullpen, but Colorado finished 1 for 9 with runners in scoring position.

"Yeah, pretty much what it usually comes down to when you don't score enough runs," Todd Helton said. "(Feldman) just made some pitches when he had to."

Charlie Blackmon had an RBI double for the Rockies in the seventh and later scored on Yorvit Torrealba's groundout.

Chacin will fly to Venezuela for his grandmother's funeral, but intends to make his next start Friday at Miami.

The team gave him a chance to skip this outing.

"They asked me, but I really want to pitch," Chacin said.

Feldman worked into the seventh inning to earn his first win in nearly a month. Davis scored three times and got hits in his final four at-bats.

After the All-Star slugger's two-out double off Chacin in the third, Jones launched his 25th home run for a 3-0 lead.

With the Orioles ahead 3-2 in the seventh, Davis and Jones hit consecutive singles against reliever Josh Outman and later scored on Brian Roberts' one-out single.

Davis smacked a two-run drive to right-center off Edgmer Escalona in the eighth.

"When those guys get rolling, sometimes you just hope they hit it at somebody," Weiss said about the Orioles' potent hitters.

Feldman allowed two runs and five hits over 6 1-3 innings for his victory since July 22.

In four previous home starts since he was traded by the Cubs to Baltimore on July 2, Feldman went 1-3 with a 7.66 ERA. In improving to 10-9 overall, he allowed only two hits through six innings.

"Feldman for six innings handcuffed us with the cutter-curveball mix," Weiss said. "Did a nice job getting through our lineup."

Nolan Arenado's infield popup with two on ended Colorado's fourth-inning threat. Feldman put a runner on third with one out in sixth via a walk and two wild pitches before striking out Troy Tulowitzki and retiring Michael Cuddyer on a fly ball.

The Rockies chased Feldman with two runs on three hits in the seventh, including doubles by Helton and Blackmon.

Early two-out hits fueled Baltimore's offense in back-to-back games. Alexi Casilla's RBI single off Chacin in the second scored Baltimore's first run.

On Saturday, Baltimore used three two-out hits to score seven runs in the third inning of an 8-4 win.

Tommy Hunter, Darren O'Day and Josh Stinson combined to work the final 2 1-3 innings behind Feldman.
