Shoulder strain hampers Donnelly

Righty to be monitored; forearm stiffness halts Eyre's rehab

SURPRISE, Ariz. -- Rangers pitcher Brendan Donnelly is being limited to long toss because of a strained muscle in the back of his right shoulder, and Willie Eyre has stopped throwing because of some stiffness in his right forearm.

Donnelly has made one appearance so far in a game. He walked two batters in an intrasquad scrimmage game and has not appeared in a Cactus League game. He threw long toss on Sunday and will continue to be monitored.

Eyre has made one appearance in a Cactus League game and pitched a scoreless inning, striking out two. But he has developed some soreness in his forearm, and the Rangers are holding him out for at least a couple of days. The soreness is not related to the Tommy John elbow reconstruction surgery that Eyre underwent in 2007, but is more consistent with a pitcher who just beginning to go full bore after an extended absence.

Other health news:

• Shortstop Joaquin Arias, who has been one of the most impressive players in camp, had to return to the Dominican Republic where his father is gravely ill. Manager Ron Washington said that Arias will be given all the time he needs.

• Brandon Boggs is still nursing a sore right shoulder. He has been able to swing a bat and was the designated hitter in Saturday's game in Tucson. But he has not yet been able to play in the field. The Rangers need him, because both Nelson Cruz and Frank Catalanotto have left for the World Baseball Classic.

• Jason Jennings, recovering from last year's right flexor tendon surgery, threw 30 pitches in a simulated game on Sunday. He'll be re-evaluated again Monday, and the next step could either be another simulated game or a Cactus League game.

• Kason Gabbard (left elbow) threw in the bullpen on Sunday without problem. His next step could be a simulated game.

• Taylor Teagarden is out with the flu. He was supposed to start on Sunday against the Mariners, but Adam Melhuse started instead.
