Sean Marshall RP CIN 3 Months

Marshall recently told that he is progressing in his recovery from shoulder surgery. "My therapy is going great," Marshall said Sept. 23. "It really is. My strength is there. I still have a little range of motion work that I've been doing, but every day is better. I definitely feel like I have a new shoulder, so it's good and strong."

Shoulder issues have plagued Marshall's tenure with the Reds, limiting him to just 31 appearances over the past two seasons. He underwent surgery June 24 to repair a torn labrum and appears on track to begin a throwing program in early-to-mid November, with the hope being that he'll be 100 percent for spring training. His return would be a big boost to a bullpen that relied heavily on just two lefties in 2014, Manny Parra and Aroldis Chapman.

Part of Marshall's surgery included an infusion of stem cells designed to accelerate the healing process. Marshall is hoping that his progress mirrors that of the Brewers' Tom Gorzelanny, who had a similar procedure.

He's slated to earn $6.5 million from the Reds next season.

Marshall threw live batting practice, and Reds manager Bryan Price said the session went well. The southpaw was bothered by shoulder soreness earlier in spring but he appears past that at this point. He's still be a few weeks behind his teammates in terms of readiness for the season -- he'll almost certainly begin the season on the disabled list -- but Marshall should be back with the club before too long.
