From Joel Sherman and George A. King III of the Post:

Hitting coach Kevin Long, who speaks daily with A-Rod, told The Post that Rodriguez has begun to hit and reported that he "feels 70 percent." Long wasn't sure if Rodriguez was hitting off a batting tee or doing flip drills. ...

A Yankees official told The Post he thought the rehab was going so well, in fact, that if the organization wanted, it could have Rodriguez back on a major league field by late April.
