Andrew Brown had three hits for the Rockies, who have won eight of 10.
The Dodgers lost Matt Kemp to a right knee contusion after he crashed hard into the wall in center field trying to chase down Josh Rutledge’s triple in the first inning. He turned into the padding while running full speed and fell backward onto the warning track.
He stayed down for several minutes as team trainers checked him over. He got up, took a drink of water and initially stayed in the game.
Not for long.
The next batter, Jordan Pacheco, looped a double that Kemp laid out for but didn’t catch. Rosario followed with a single to center to score Pacheco, and Kemp left after fielding the ball.
He left the ballpark to have precautionary X-rays on his jaw, the Dodgers said. The team said he had no concussion symptoms.
The Dodgers got a run back on a sacrifice fly by A.J. Ellis in the second inning.
Rosario made it 5-1 with his 22nd homer in the third.
Capuano (11-10) allowed six runs, 10 hits and struck out three in six innings. It was the second consecutive game he has allowed six earned runs.
The Dodgers loaded the bases with no outs in the fourth but scored just one run on Adam Kennedy‘s double-play grounder.
Colorado padded the lead with a run in the bottom of the fourth and two more in the seventh off reliever Jamey Wright.
Chatwood (4-3) battled through five innings to get the win. He allowed two earned runs, walked three and struck out four.
Ramirez led off the ninth with his 21st homer of the season to make it 8-4.
