Astros' Chas McCormick: Begins rehab assignment

McCormick (back) could need six or seven rehab games, which start Saturday with Double-A Corpus Christi, Julia Morales of AT&T SportsNet Southwest reports.

We knew McCormick would begin his rehab assignment this weekend, but it's worth noting that manager Dusty Baker expects it to be a longer rehab assignment than is sometimes needed for a position player. In the meantime, Jake Meyers will continue to be Houston's primary center fielder.
