Urquidy (shoulder) will go to West Palm Beach on Wednesday to begin his rehab assignment, Chandler Rome of the Houston Chronicle reports.
Manager Dusty Baker expressed hope that Urquidy would be back with the Astros on Sept. 1. The righty has been on the IL with a right shoulder injury since June 30. To date he has posted a 3.38 ERA and 66:13 K:BB in 77.1 innings. Once healthy, Urquidy figures to rejoin Houston's starting rotation.
