Shaun Marcum (thoracic outlet surgery) resumed throwing from a mound Monday. Coming back from thoracic outlet surgery, Marcum is a little behind the other Indians pitchers but threw 25 fastballs and changeups Monday with no issues. The veteran right-hander will compete for the final spot in the Tribe's rotation, but manager Terry Francona says it's not a given that Marcum will be ready for Opening Day. "He's worked too hard," Francona said. "It never fails, you come to Spring Training, everybody's all geared up, the volume of throwing increases and then you have looming Opening Day. But I think that's an artificial deadline. We tried to beat that home with a lot of guys, that that is not the end all. Keep the big picture in mind."
