Rockies 10, Braves 3: Justin Morneau homered and drove in three runs in support of seven scoreless innings from Jhoulys Chacin as Colorado crushed visiting Atlanta to earn a split of the four-game series.

Charlie Blackmon added a two-run blast among three extra-base hits and also drove in three runs while Chacin singled and scored for the Rockies, who have won two straight after dropping 11 of 12. Chacin (1-4) allowed two hits and walked a pair while striking out five to pick up his first win since Sep. 20.

Tommy La Stella doubled among two hits, B.J. Upton homered and Jason Heyward drove in a run for the Braves, who finished out their seven-game road trip with a 3-4 mark. Ervin Santana (5-3) was knocked around for six runs on seven hits and a pair of walks while striking out eight in 6 1/3 innings.

Colorado got leadoff doubles in the first and second innings but could not push a run across until the third, when Chacin reached with a one-out single and Blackman followed by wrapping a 1-1 slider just inside the foul pole in right for his 12th home run. Morneau sent a changeup into the Atlanta bullpen with two outs in the sixth to make it a 3-0 gap.

Chacin issued a pair of walks in the seventh but escaped the jam with an inning-ending double play before the Rockies tacked on five more runs in the bottom of the frame. Charlie Culberson plated a run with a single, Ryan Wheeler delivered a pinch-hit sacrifice fly and Morneau continued his big afternoon with a two-run single before Josh Rutledge scored on a wild pitch to make it 8-0.
