So, Johan Santana is having major surgery. How major? Injury expert Will Carroll is promising a writeup over at Baseball Prospectus on Monday, but he provided a link to an explanation of the rehab program for the surgery Santana is getting. There’s a lot of jargon in there, but it’s pretty clear that the time table for the rehab is 24 weeks, though he can — according to the linked article — throw at 20 weeks, which is mid-February.
But note that is “throwing,” not “pitching.” And it’s worth noting that the press release regarding Santana’s injury
said that he would begin “throwing” by spring training. In light of that, it’s an open question whether Santana will be ready to pitch
on Opening Day 2011. It’s also an open question if he’ll be the old
Johan Santana or if he will be but a shell of himself following what
appears to be major surgery.
