Rockies 7, Nationals 1: DJ LeMahieu belted his first homer among his three hits and Jhoulys Chacin tossed seven scoreless innings as visiting Colorado erupted from its offensive doldrums to snap a season-high five-game losing skid.
Michael Cuddyer added an RBI single in the three-run first inning to extend his hitting streak to 20 games - matching St. Louis' David Freese for the longest in the majors this season. Cuddyer also reached base for a franchise-best 39th consecutive contest, breaking the 2007 mark of Matt Holliday.
Corey Dickerson, who was recalled from Triple-A Colorado Springs on Friday, capped the frame with a run-scoring double in his major-league debut. Chacin and LeMahieu added RBI singles during a three-run fourth inning to close the book on struggling starter Dan Haren (4-9), who fell to 0-6 in his last eight outings and saw his ERA balloon to 6.15.
The offensive explosion was certainly welcome by Colorado, which scored a total of seven runs during its losing skid. Chacin (6-3) scattered five hits to win his third straight outing and defeat Haren and Washington for the second time in 11 days.
LeMahieu got the fireworks started in the first inning after he deposited a 1-0 cutter from Haren into the bullpen in left-center field. The 24-year-old, who finished 3-for-5, is 9-for-21 in his last five games.
GAME NOTEBOOK: Washington OF Bryce Harper doesn't feel his ailing knee will be ready to play in a rehab game at Class-A Potomac on Tuesday, as suggested by manager Davey Johnson. "Tuesday, that's kind of early," Harper said of the contest. "I'm thinking Wednesday or Thursday maybe. I'm not sure. We'll see how I feel." ... Colorado 3B Nolan Arenado extended the lead to 7-0 with a homer in the eighth inning before Washington 3B Ryan Zimmerman answered with a solo shot in the ninth to break up the shutout. ... Nationals RF Jayson Werth was scratched for an unspecified reason and replaced in the lineup by Steve Lombardozzi, who played in left field. Roger Bernadina shifted to right field. Werth had missed 28 games with a strained hamstring before returning on June 4. ... Chacin yielded two runs in five innings in the Rockies' 8-3 win over the Nationals on June 11. Haren took the loss after allowing five runs and eight hits in five frames.
