Ryan Zimmerman has inflammation

SAN DIEGO -- Washington Nationals manager Davey Johnson says an MRI on Ryan Zimmerman's right shoulder shows inflammation but no structural damage.

Zimmerman missed his third straight start on Wednesday. Johnson says the plan is to have Zimmerman take some swings on Thursday to see how he feels.

If there's no relief by Thursday, Zimmerman could be sent back to Washington for treatment.

Johnson says Zimmerman had a cortisone shot on Saturday but it's possible the shot might not have had its full effect.
