DENVER (AP) — Stephen Strasburg pitched seven strong innings, Jayson Werth hit a tiebreaking triple in the eighth and the Washington Nationals rallied to beat the Colorado Rockies 4-1 on Wednesday night.

Strasburg (7-6) allowed just two hits, struck out five and didn’t walk a batter in his third straight solid start since coming off the disabled list.

The Nationals tied it in the seventh when reliever Gonzalez Germen allowed a two-out double to Bryce Harper and then threw a wild pitch with the bases loaded to tie the score at 1-1.

Washington again mounted a two-out rally off Rafael Betancourt (2-4) in the eighth. Wilson Ramos singled, pinch-hitter Clint Robinson walked and Werth lined a triple over the glove of right fielder Carlos Gonzalez.

Zimmerman added an RBI single in the ninth and Jonathan Papelbon got the final three outs for his 20th save and third with Washington.
