Rangers' rotation in flux with Grimm, Darvish hurting

DETROIT -- Right-hander Justin Grimm was still feeling some stiffness in his forearm on Saturday after having to exit Friday's game against the Tigers in the fourth inning. His uncertainty is one reason why the Rangers haven't set their rotation for after the All-Star break.

Grimm is getting treatment and may try to throw on Sunday. If that doesn't go well, he'll likely be examined further by Dr. Keith Meister during or immediately after the break.

Yu Darvish, who is on the disabled list with a strained trapezius in his right shoulder, rejoined the Rangers on Saturday but did not resume throwing. Instead he limited his work to running and light exercises. Darvish is planning to join outfielder Nelson Cruz and reliever Joe Nathan for the All-Star Game festivities in New York next week even though he is unable to pitch in the game.
