Sean Marshall (shoulder) felt good Tuesday after pitching off flat ground. "I jammed it out yesterday, 35 pitches," said Marshall, who has been sidelined since May 20 with a lingering shoulder issue. "It felt good. Usually when I take a day off, I get a little bit out of sync but yesterday was good and today should be great." Marshall thinks he could throw a light bullpen session at some point this weekend. The southpaw could return in the early part of July if he can avoid setbacks.
