Strasburg loses grip as Rockies top Nationals Tue Jun 26, 2012 12:16am EDT (Reuters) - The Colorado Rockies handed Washington ace Stephen Strasburg his first defeat in more than a month with a 4-2 victory over the visiting Nationals on Monday. Strasburg (9-2) had won his last six starts, but the Rockies got to him in the sixth inning where the hard-throwing pitcher lost his control and hit Marco Scutaro in the head. Scutaro had to leave the game and Strasburg exited not long after, picking up his first loss since May 15. Carlos Gonzalez and Todd Helton batted RBIs for Colorado in the pivotal sixth to grab a 3-2 lead and help the struggling Rockies (28-44) beat the National League East leading Nationals (41-30). Rockies starter Jeff Francis tossed five innings in his second solid outing in a row since being signed by Colorado earlier this month. Reliever Josh Roenicke was credited with the win after keeping Washington scoreless in the sixth and seventh where the home team added a final run on a Chris Nelson single.
