NEW YORK -- The latest Rangers' pitching injury comes courtesy of a hotel room door.

On Saturday, the club placed left-hander Martin Perez on the 10-day DL, retroactive to Friday, with a small fracture at the tip of the thumb on his right (non-pitching) hand. Perez tore the nail off the thumb after catching it in a door in his hotel room. Perez, who was sporting a padded thumb splint Friday, suffered the injury Thursday night after the team arrived in New York. Perez pitched Thursday.

The Rangers, however, will get Cole Hamels back after a seven-week absence. Hamels will pitch Monday in Cleveland, the team confirmed. Hamels has been out since May 3 due to a strained oblique muscle.

In the meantime, the Rangers recalled INF-OF Drew Robinson from Triple-A Round Rock to replace Perez.

Perez did not initially intend to go on the DL.

"My bullpen is [Saturday] and I'm going to throw it," he said Friday. "And I'm not going to miss a start. As long as I can perform my job and protect it, I am going to pitch. Accidents, man, they happen."

Perez indicated that he was in his hotel room with his hand resting against the door jam when somebody opened the door, squeezing his thumb. He immediately called athletic trainer Kevin Harmon, who took him to a hospital where the nail was reattached and X-rays showed a small fracture.

Hamels, on the DL since May 3 with a strained oblique, threw a typical between-starts bullpen session Friday, two days after his 5 2/3-inning rehab start at Double-A Frisco. Andrew Cashner, who has a more minor oblique strain, is hoping to throw a bullpen session this weekend. If he does, manager Jeff Banister and pitching coach Doug Brocail indicated he could return without a rehab start or facing hitters in a simulated game. He has only missed one start to this point.
