Juan Jaime

Jaime was able to overcome his control issues to a large extent at Triple-A Gwinnett last season, managing a 3.51 ERA and 18 saves despite a 7.9 BB/9, but it was a different story at the major league level. Although he enjoyed some initial success upon his promotion in June, Jaime walked nine and gave up eight earned runs in 12.1 innings with the big club (5.84 ERA), while working exclusively in mop-up duty. The right-hander averaged better than 96 mph with his fastball and used it generate a 29.0% strikeout rate, but it's hard to imagine that a switch will go off and he'll suddenly be able to hit the strike zone consistently, making it unlikely that he'll be entrusted with high-leverage work in 2015.
