Marshall was scheduled to have season-ending surgery last Wednesday to repair a torn anterior capsule in his left shoulder. However, when New York Mets medical director Dr. David Altchek performed the procedure, he instead found only significant scar tissue from Marshall's June 2014 surgery to repair a torn labrum. The scar tissue was cleaned up, a biceps tendon was moved, and Marshall returned to a Reds clubhouse Monday that seemed cheered by his arrival.
"It's nearly a miracle," Reds manager Bryan Price said. "What a difference a day makes. He's fired up."
Marshall said he tried to maintain realistic hopes, like being able to one day pitch batting practice to his children in his back yard.
"It was a huge breath of fresh air," Marshall said of the good news he received post-surgery. "It took a while to set in."
Marshall said that the volume and thickness of the scar tissue created difficulty in being able to get a full view of the shoulder capsule, leading to the original diagnosis.
"It was really affecting my range of motion," Marshall said.
Marshall also battled shoulder tendinitis in 2013 after having led the Major Leagues with 231 appearances from 2010-12, including a team-high 73 games in 2012. He was traded from the Chicago Cubs to the Reds prior to that season for three players, including Travis Wood. Before the 2012 season began, the Reds signed Marshall to a three-year, $16.5 million contract extension through 2015. He is making $6.5 million this year.
"A lot of people have been praying for me," Marshall said. "Hopefully those prayers were answered."
• Price said he would not be able confirm if Johnny Cueto (elbow stiffness) will return to the Cincinnati rotation until the results are available Tuesday from Monday's examination by team physician Dr. Tim Kremchek.
"I don't think it's a serious injury," Priee said. "We should have a pretty good idea by [Tuesday] afternoon. The medical staff seems confident it doesn't appear to be anything that would put him on the shelf for a long time."
