PHOENIX -- Ryan Zimmerman missed his seventh consecutive game on Sunday because of his sore left shoulder.
Zimmerman will have an MRI on Monday in Washington. The third baseman was hurt sliding headfirst into second base against the Orioles on May 18.
Zimmerman took batting practice on Saturday and still felt pain in the shoulder. In the first two rounds of the session, Zimmerman was taking soft swings. By the fifth round he was swinging the bat harder, hitting a ball over the fence.
A day later, Zimmerman said he is taking a wait-and-see approach as far as playing goes.
"I feel all right," Zimmerman said. "It's not worse than it was before. Let's see how it reacts on Tuesday and, hopefully, I'm feeling better. We'll see how it feels. It's a day-to-day kind of thing. It's hard to predict either good or bad."
Meanwhile, right fielder Austin Kearns is expected to rejoin the team on Tuesday in Washington. Kearns had surgery to remove loose bodies from the right elbow. Acta said Kearns almost has his range of motion back. Kearns is expected to miss an additional three weeks of action.
Infielder Ronnie Belliard, who has been on the disabled list because of a left calf strain, is expected to participate in on-field activities, which includes taking ground balls and running the bases this coming week.
