Tyler Colvin homered twice off Stephen Strasburg to back a masterful pitching performance by Drew Pomeranz and lead the Colorado Rockies past the Washington Nationals 5-1 Friday night.

Colvin hit a solo shot in the second inning and a two-run drive in the fourth to become the first player to hit two home runs against Strasburg in the same game. Colvin also singled in the sixth off Strasburg and hit a fly ball to the warning track against Ryan Mattheus in the eighth.

Strasburg (9-4) allowed three runs, two earned, and eight hits in six innings. The All-Star struck out six and walked only one, but lost a third straight start for the first time in his three-year career.
