Zimmerman's fractured thumb not yet healed

PHOENIX -- Nationals third baseman Ryan Zimmerman recently had X-rays done on his fractured right thumb, and they revealed that he is not close to doing any thumb exercises. The problem is that the thumb hasn't healed. There is no timetable as to when it will be 100 percent.

"The doctor is not comfortable with him doing any strengthening stuff -- yet," manager Matt Williams said. "I imagine we go back to that within a week and see where he is at. .. It's been four weeks and he is not quite there yet."

Zimmerman fractured his thumb against the Braves on April 12 while going back to second base on a pickoff attempt. With the Braves leading, 4-1, in the fifth inning, Zimmerman hit a one-out double before being picked off by left-hander Alex Wood. Zimmerman then looked at his right hand and was slow to get up. He then walked into the dugout and was taken out of the game.

Anthony Rendon will continue to be the everyday third baseman until Zimmerman returns to the lineup.
