Yhonathan Barrios

Barrios, a converted infielder, fared reasonably well in his first professional season as a pitcher. After being acquired by the Brewers in June and sent to Double-A Biloxi, he posted a 3.15 ERA with six saves, which led to a late-September promotion. He performed well during his time with the Brewers, tossing 6.2 scoreless innings. His 31.8% K-rate in that brief run with Milwaukee dwarfed his K-rates in the minors, so it remains to be seen how real that spike was. Depending on injuries and the performance of veterans on the major league club, Barrios could see some time in the bullpen for the Brewers this year if he can pick up where he left off at the end of 2015.
