MIAMI - Nolan Arenado hit a tiebreaking RBI double in the sixth and the Colorado Rockies held on for a 4-3 win over the Miami Marlins on Sunday.
Jorge De La Rosa (14-6) won his fourth consecutive decision, allowing three runs in five innings. De La Rosa improved to 7-0 with a 1.92 ERA in day games.
Five relievers then combined for four hitless innings, with Rex Brothers working the ninth for his 13th save in 14 chances. With runners on first and second, Brothers got Ed Lucas to ground into a fielder's choice to end the game.
Miami's Justin Ruggiano homered and drove in two runs.
