ARLINGTON -- Rangers pitcher Derek Holland, who has been on the disabled list all season while recovering from surgery on his left knee, said he has still not been told when he will be sent to the Minor Leagues on a medical rehabilitation assignment.
Holland will likely have to go through more fielding drills this weekend to test the strength of the knee before the Rangers clear him to pitch in a game. The club is still concerned Holland's knee isn't quite strong enough to hold up to the rigors of fielding his position.
Holland has been throwing regularly and believes he will be able to pitch at least four-five innings right from the outset of a rehab assignment.
"I haven't heard anything, but the only thing I don't want happen is I'm out there for just two innings and 35 pitches," Holland said. "That better not happen. I have been throwing 80-pitch bullpens."
Holland did admit he needs to show more than just strength and endurance on his rehab assignment. He needs to show he can get Major League hitters out.
"I want to make sure things are right," Holland said. "If I'm not having success, don't send me up here. I want to make sure I'm ready to go."
