Zimmerman will have a similar session and take batting practice on Sunday, and will look to return Tuesday against the Pirates.
"Nothing hurt yesterday, but I felt way better today than I did yesterday," Zimmerman said Saturday. "Whenever you come down with something, you are a little cautious at first. It was pretty much 100 percent today. I felt fine. If I improve again tomorrow, I hit BP and [show manager] Davey [Johnson] [that I can] go through my workout -- which I usually do before the game -- I'm ready to play."
Zimmerman hurt his shoulder after making several diving plays at third base during the month of April. Asked if he would do anything differently in terms of playing defense, Zimmerman said, "Unless you want me to stop diving for the ball. Those are things that happen. You play enough games and you are fortunate enough to be here long enough, you are going to get hurt. Unfortunately, I had to miss some time. Sometimes, you can play through it. Sometimes, you can't."
