The Cubs opted for versatility over their need for another left-hander in their bullpen when they recalled right-hander Casey Coleman from Class AAA Iowa after putting Carlos Marmol on the disabled list Saturday. Coleman, who was in the starting rotation at Iowa, joins the bullpen as a potential matchup reliever, obviously capable of pitching multiple innings per appearance. The Cubs' bullpen has been heavy on one-inning guys. ''He's the kind of guy you can use in different roles, depending on what's going on that day,'' manager Dale Sveum said of Coleman, who allowed two runs and four hits in two innings in the Cubs' 8-2 loss Saturday to the Milwaukee Brewers. ''He's got the slider, he's got different arm angles, a guy you could use if right-handers are coming up, things like that. And he's definitely a guy you're going to want to use two innings all the time, whenever he's getting used.'' Sveum said an MRI exam Saturday showed ''very minimal'' damage to Marmol's right hamstring. ''It wasn't significant at all, so 15 days and we'll go from there,'' Sveum said.
