New Boston Red Sox left-hander Chris Carpenter announced via Twitter he underwent surgery to remove bone chips from his elbow. The surgery will cost Carpenter an undetermined amount of time this season.
It also reopens the Theo Epstein compensation talks with the Chicago Cubs. The Red Sox received Carpenter as the primary compensation for allowing Epstein to leave before his contract expired and become the Cubs' president of baseball operations.
Red Sox president Larry Lucchino said the team isn't satisfied with the resolution to the situation, especially because Carpenter is injured.
"[GM] Ben Cherington has had some discussions with the Cubs exploring this issue, but there is nothing to comment on beyond that right now," Lucchino said.
Asked if he believed the Cubs acted in good faith when they traded Carpenter to the Red Sox in late February, Lucchino said, "I think so."
Carpenter appeared in just two games this spring but pitched poorly. He passed the Cubs' spring training entrance physical and pitched fine early in Cubs camp before the trade. Moreover, his medical records passed the Red Sox's review, and Carpenter passed their entrance physical as well.
