The Cubs have placed Carlos Marmol on the disabled list with a strained right hamstring and recalled right-hander Casey Coleman from Triple-A Iowa. Marmol was injured in the seventh inning of Friday night's 13-inning marathon when he delivered a pitch to Milwaukee's Corey Hart. Six of Coleman's seven appearances at Iowa were starts. He posted a 2-3 record with a 3.48 ERA in 33 2/3 innings and had 30 strikeouts and 16 walks. He is expected to be used as a long man out of the bullpen.
