RHP Angel Guzman presents an interesting situation as the chief right-handed setup man to RHP Carlos Marmol, who took over as closer in the second half of the 2009 season. Guzman, who turns 28 on Dec. 14, enjoyed his best and busiest year by working in 55 games and turning in a 3-3 record with a 2.95 ERA. However, Guzman's career had been plagued by arm and shoulder problems, and the Cubs shut him down for the final two weeks of the season because of triceps soreness. If Guzman can stay healthy, his stuff is electric.
