Hamilton (hamstring) went 1-for-3 with a double and a walk in his first rehab game Wednesday at Double-A Frisco, The Dallas Morning News reports. Hamilton is scheduled to join the Rangers' Triple-A affiliate at Round Rock on Thursday and play with them through the weekend. That said, Hamilton served as the DH on Wednesday and will need to test the hamstring in the field before being activated from the disabled list. Provided the hamstring feels fine on Thursday, he should have the green light to play through the weekend at Round Rock.
