Sheets, 31, is recovering from elbow surgery last season. He rehabbed for most of 2009 in Arlington, working with Rangers physician Dr. Keith Meister. The Rangers did get some medical records on Sheets and are reviewing them.
The Rangers had a deal in place with Sheets last offseason before the pitcher failed a physical and opted for surgery. He interests the club if they can structure a deal that includes some incentive-based bonuses that give the team some protection if he isn't completely healthy.
Sheets could be the type of free agent who isn't signed until later in the offseason once he has a better idea of his market value and if teams get a chance to see him throw.
