Keith Butler

Butler was in line to be a solid member of the Cardinals' bullpen in 2014 after posting a 4.05 ERA in 20 innings during the 2013 season, but early season struggles forced him to Triple-A where he appeared to be getting on the right track, posting a 0.84 ERA in nine appearances across 10.2 innings. In May, Butler began having elbow issues that eventually led to Tommy John surgery. He will likely be sidelined for half the season in 2015, if not longer, and is unlikely to provide any fantasy value in 2015 as a result of the lost time. The Cardinals outrighted him to Triple-A during the offseason, removing Butler from the 40-man roster.
