Jason Castro had his right knee drained today in an effort to stave off surgery, says Brian McTaggart. Castro also had a shot in the knee, hoping that he'll be able to return to Houston's lineup next week.
Jeff Luhnow had originally been optimistic that Castro would be back on Monday, as soon as he's eligible to return from the 15-day DL. But now it sounds as though he may go out on a brief rehab assignment to test the knee before returning.
