On May 13, 2013 — Jordan Zimmermann is the first major league pitcher to seven wins as he also drives in three runs in Washington’s 6 – 2 victory over the Dodgers. His opponent, Josh Beckett, falls to 0-5. For Washington, Bryce Harper runs at full speed into the outfield fence in the 5th inning as he attempts to catch a fly ball hit by A.J. Ellis; he has to leave the game and while he will return to action quickly, the nagging injuries resulting from the collision will affect his production significantly for the rest of the season.
