The milestone was reached in the first inning, when Zimmerman took Jon Garland's 1-2 pitch and hit the ball over the right-center-field wall to give Washington a 1-0 lead. It was Zimmerman's first long ball since May 13 against the Rockies in Colorado.
"Obviously, it's an accomplishment," said Zimmerman who made his debut in late 2005. "But it's not something I've been waiting to happen. If it happens, it happens. I'm proud of what I've done. I keep working hard. Hopefully, I'll hit some more."
Zimmerman later hit his 101st career homer, another solo shot that tied the score at 2 in the top of the sixth inning. It was Zimmerman's seventh multi-homer game of his career.
