Yankees SS Didi Gregorius will begin playing in rehab games on Friday for High-A Tampa, the team announced Tuesday.
Gregorius, who is dealing with a hematoma of the subscapularis muscle in his right shoulder, began a throwing program two weeks ago.
"I don't want to rush anything, because if something happens, it's going to be even worse with a setback," Gregorius said after beginning his throwing program.
He was diagnosed with the inury in March, which the Yankees expected would keep him out for six weeks.
The 27-year-old went 1-for-5 in two Grapefruit League games before leaving for the World Baseball Classic, and was hitting .348 (8-for-23) with one HR, eight RBI and four doubles while representing Netherlands in the tournament.
In 153 games for the Yankees last season, Gregorius hit .276 with 20 HR, 70 RBI, and 32 doubles.
