The Chicago Cubs recalled right-hander Casey Coleman to take Carlos Zambrano's spot in the rotation and start Wednesday's game in Houston.

Coleman, 24, was recalled from Triple-A Iowa for the fourth time this season. He is 2-4 with a 7.23 earned run average in 11 games this season, including nine starts.

Much of that came during Coleman's first call up, which lasted from April 9 to May 28. He was also recalled on June 11 and July 4, but sent back down within a few days after one appearance both times.

Coleman, the first third-generation pitcher in major league history, is making his 18th career start. His grandfather and father were former All-Stars.

Zambrano was placed on the disqualified list Saturday, one day after he was ejected for throwing at Atlanta's Chipper Jones twice and after he had cleaned out his locker and said he was retiring.
