BOSTON -- Results from an MRI on Tuesday afternoon confirmed the original diagnosis that Colby Rasmus has a strained right hamstring.

Rasmus is currently on the 15-day disabled list and hasn't played since May 12 vs. the Angels. He was sent for the precautionary MRI to rule out any type of major structural damage. With the results confirmed, the hope is that Rasmus will return by the beginning of June.

A return date for right-hander Sergio Santos is also unknown, but he's scheduled to resume throwing on Friday. Santos has been out since May 9 with a strained right forearm, but he will require more time than just 15 days on the DL.

Santos will need to throw at least a couple of side sessions before eventually going on a rehab assignment in the Minors. If there's any setback along the way, Santos could be out for a significant period of time. For now, things appear to be moving in the right direction.

"It won't be long," manager John Gibbons said. "He's going to start throwing the ball around when we get home. See where he's at. He said he's feeling good, I know that."
