2017 stats: 47.0 IP, 1-4, 4.79 ERA (3.73 FIP), 1.55 WHIP, 5.0 K/9, -0.7 WAR (Baseball Reference)
By looking at the stat line above, one could come to the conclusion that Brad Ziegler, who the Marlins signed on a two-year, $16 million contract before the season began, had a bad year. There is evidence to back that up as, overall, the 37 year-old posted career highs in ERA and WHIP, and a career low in innings pitched.
So, bearing in mind that he was brought in alongside Junichi Tazawa to form a Marlins 'super bullpen’, should Ziegler be considered a bad investment and a sunk cost moving forward?
