CLEVELAND -- The Indians' main acquisition from the Cliff Lee trade is no longer part of the organization.
The Tribe released right-handed pitcher Jason Knapp on Wednesday, a player Cleveland got from the Phillies in the 2009 blockbuster Trade Deadline deal involving Lee.
Knapp, 20, had two operations on his throwing shoulder, and he hadn't pitched in a game in more than two years. Knapp pitched at the team's year-round training facility in Goodyear, Ariz., after the first surgery to repair a torn labrum in 2009, but he continued to feel discomfort in the shoulder and had to be reevaluated last summer.
Knapp underwent the second operation last June after leading Class A Lake County to the Midwest League championship series in 2010. He had been having regular checks with Dr. David Altchek, but hadn't even been throwing recently.
"It got to the point where that was the best route," said Indians general manager Chris Antonetti. "We obviously tried the rehab route with him a number of times. Jason, to this point, has been unable to get on a mound or get to a point where he's comfortable pitching consistently."
Knapp was a second-round pick of the Phillies in 2008. He had a 3.63 ERA in 156 1/3 career Minor League innings, with 208 strikeouts and only 71 walks.
The Indians also received pitcher Carlos Carrasco, catcher Lou Marson and infielder Jason Donald in the Lee deal. Carrasco is currently rehabbing an elbow injury, and the team expects him to be ready for Spring Training next year. Marson is hitting .244 with nine RBIs in 45 games for the Indians this season, and Donald is currently playing at Triple-A Columbus.
