Corey Hart stated Friday that he is already ahead of schedule in his rehabilitation after surgery on his right knee, and if things continue at his current pace he could be ready to play by the end of April. Hart will have an MRI done in three weeks, and barring any setbacks he could beat his projected recovery time by a full month with a late-April return. While it's encouraging news, Hart owners still shouldn't expect him back until sometime in May. Mat Gamel will hold down the fort at first base in his absence.
