According to MLB.com's Alyson Footer, Brandon Backe has cleared waivers and rejected an assignment to Triple-A Round Rock. He is now officially a free agent.
Backe was designated for assignment last week after allowing 15 runs and 21 hits in 13 innings (one start) for the Astros. He's 31-29 lifetime with a 5.38 career ERA. At just 31 years of age, perhaps a few clubs will have interest in providing the right-hander both a change of scenery and a fresh start.
