"Nationals manager Jim Riggleman spoke to third baseman Ryan Zimmerman on Thursday. Zimmerman, who is on the disabled list after surgery to repair an abdominal injury, is performing baseball activities -- taking batting practice, hitting off a batting tee, taking ground balls and long tossing -- at the team's complex in Viera, Fla. "He is feeling good about his work down there. He is feeling better, but he has a way to go yet," Riggleman said. The Nationals are hoping that Zimmerman can play in a Major League game by mid-June. Zimmerman had problems with his groin and his abdomen during Spring Training, and he recovered from both before hurting the abdomen again in the first few games of the season, landing him on the disabled list."
