Zimmermann, ‘pen blank Rockies; Nats at .500 at break

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.
