Zimmerman got hurt diving back to the bag as he was picked off second base in the fifth inning Saturday night. He stayed on the ground for a minute before finally leaving the field.
Before the game, the Nationals placed center fielder Denard Span on the seven-day disabled list with a concussion. Right fielder Jayson Werth was held out after leaving Friday night's game with cramping in his groin. Werth had a pinch-hit single.
