Jordan Zimmermann pitched 6 1/3 innings of shutout ball, Roger Bernadina snapped a scoreless tie with an RBI single in the sixth and the Washington Nationals reached .500 at the All-Star break with a 2-0 victory over the Colorado Rockies on Sunday.
The Nationals' 46-46 record at the break gives them seven more victories in three more games than at the 2010 hiatus, when they were 39-50. Sunday's victory broke a three-game losing streak, with four pitchers combining on a six-hit shutout, Washington's sixth of the season.
Zimmermann (6-7) kept the Rockies at bay until Bernadina broke through by engaging in a pitchers' duel with Colorado right-hander Jhoulys Chacin. Zimmermann allowed four hits, didn't issue a walk and struck out six.
Ryan Mattheus got the final two outs in the seventh, Tyler Clippard worked the eighth and Drew Storen got the final three outs for his 23rd save.
Chacin (8-7) retired the first 11 Washington hitters in order before Ryan Zimmerman's two-out single to left in the fourth. Washington finally broke through in the sixth, when Ian Desmond reached on an infield single, moved to second on Zimmermann's sacrifice bunt and scored on Bernadina's broken-bat single to right.
Chacin yielded a run on four hits over seven innings. He walked one and fanned four, but dropped his third straight decision.
Rick Ankiel homered off Matt Reynolds in the eighth,doubling the lead. It was his third homer of the season.
