HOUSTON (AP) – The Chicago Cubs recalled left-hander Scott Maine from Triple-A Iowa on Monday to fill the empty roster spot after starting pitcher Carlos Zambrano was placed on the disqualified list.  Maine is 0-0 with a 10.29 ERA in seven games this season. He last pitched for the Cubs on May 30 against Houston, allowing three
runs in an inning. For his career, Maine is 0-0 with a 4.95 ERA in 20 games.  The Cubs were left with an open roster spot when they placed Zambrano on the disqualified list Saturday. He cleaned out his locker and left the team after giving up five home runs and being ejected Friday in Atlanta. He did not return to the team Saturday.
     The Cubs said Zambrano would not receive pay or be allowed to participate in team activities during the 30-day suspension.
