Sean Marshall (shoulder) threw his latest bullpen session Tuesday. Marshall threw 42 pitches at maximum effort while coaches stood in at the plate to simulate batters. "It went great," said Marshall. "I used all of my pitches -- backdoor sliders, curveballs -- mixing pitches like it would be in a game. I'm not sore today." Marshall has been out since late May due to a sprained left shoulder, but he has been throwing for nearly two weeks now. It's not clear when he'll go out on a minor league rehab assignment, but it sounds like he's getting close.
