Santana (back) has returned to the lineup for Game 1 of Thursday's doubleheader with the Indians, MLB.com reports. Though it was thought Santana would return to the lineup Wednesday, the team determined the 23-year-old could use one more day of rest to aid his strained back. With Santana enduring no setbacks over night, he'll slot back into center field and bat leadoff for the twins in the first half of a twin bill. There's still a good chance that he could get the nightcap off as a precaution, but Santana otherwise looks to be in good shape for regular duty heading into the weekend.
