Jake Barrett

Barrett started the 2016 season in the middle of the Arizona bullpen but found himself thrust into a more prominent role following the trades of Tyler Clippard and Brad Ziegler. The promotion didn't go well as Barrett finished with more blown saves (five) than converted saves (four). August was particularly brutal, as Barrett posted a 9.00 ERA and 2.36 WHIP across 11 innings. However, the young righty showed signs of life in the season's final full month, tossing 9.2 scoreless innings in September with seven strikeouts. That's admittedly a small sample size, but it could help him in the battle for primary setup duties entering 2017. Daniel Hudson, Randall Delgado and Enrique Burgos all figure to be in the mix for the job in front of Fernando Rodney.
