"I feel very good with my mechanics now and how I'm throwing the ball," Marmol said Wednesday. "I just want to go out there and be myself."
Last spring, the Cubs' closer totaled nine innings in Cactus League games, and got off to a good start with seven saves in his first nine chances. He posted a 1.98 ERA in the first month. In 2010, Marmol pitched in 12 spring games, totaling 12 1/3 innings. More work may be good to help him get a feel for his trademark pitch.
"My slider, I know is going to be there," he said. "Now is the time to work on my fastball. I know it's going to be tough, but I'm going to hang in there."
