"Right now we expect him to go through a normal spring training, but the ultimate test is going be how he responds and whether he's able to come back, as I said, on normal days' rest," Alderson said. "I don't think that's anything we can predict with any accuracy. I certainly can't assure you that that's going to happen, but that's certainly what we hope and right now what we expect."
Santana has battled injuries during the back end of his career and has not pitched a Major League game since September of 2010.
The former Cy Young Award winner won 11 games with a 2.98 ERA during his last full season in 2010. Despite his low ERA Santana struck out only 6.51 batters per nine innings – his lowest output since 2001. His average fastball was only 89 MPH that season, down from a career average of 91.
