Zimmerman missed 13 games on the disabled list with inflammation in the AC joint of his right shoulder. Since returning May 8, Zimmerman has hit .273/.365/.364 with one homer, which he hit Saturday, and two doubles in 63 plate appearances. Last night, Zimmerman went 0 for 4 with two strikeouts.

The Nationals labeled one other scratch this year a “manager’s decision,” in Los Angeles on April 29 with Jayson Werth. It turned out Werth missed the game with a migraine headache and returned for the Nationals’ next game.

For tonight, we only know that Tracy will get a surprise start on his 32nd birthday.
