Further updates on Justin Verlander and his recovery in an
MLB.com article here.
Summary: He's being careful with what he does and how much he pushes himself, keeping in close touch with the medical staff and the doctor who performed the surgery on him. He does not expect to be ready for the start of the Grapefruit schedule, but plans to throw 5 games during ST.
As long as he doesn't injure himself or experience a setback, he'll be ready for Opening Day.
