Gray (back) will begin his throwing program on Tuesday after getting cleared by Dr. Anthony Romeo, Susan Slusser of the San Francisco Chronicle reports.

Initially Gray was shut down from throwing for three weeks, and he was cleared to resume tossing at the two-week mark, which is promising. It would appear the 27-year-old is ahead of schedule for his late-April return date, but Gray continues to emphasize that he remains without a timetable. He'll toss from 75 feet on Tuesday, and barring any setbacks, he should continue to ramp up his workouts until he is ready to return in mid-to-late April.
