Wells to Face Oswalt, Marshall to Pen For Now

Thanks to a rainy Friday in Chicago, Randy Wells has been bumped to Saturday's game against Roy Oswalt and the Houston Astros. Sean Marshall, originally scheduled to face Oswalt, will spend a turn of the rotation in the bullpen. He's expected to start later next week against St. Louis, according to cubs.com.

The Astros flipped Friday starter Brian Moehler to Sunday, knocking Felipe Paulino off the Cubs' radar screen. Moehler will face Rich Harden. Sunday's High-A game for the Daytona Cubs will feature Carlos Zambrano, making a rehab start. Cubs.com says Big Z could be back to face the Friars on May 22 in San Diego.
