Matt Shoemaker has gone from undrafted to fan favorite over the course of his career. At his best, he is a sinkerball machine who creates wormburners and outs. When that sinker isn’t sinking, however, it tends to get hit hard.
For those unfamiliar with ERA+, it is a statistic that is adjusted for ballpark and league with 100 being an average performance. In this case being above 100 is a good thing and being below is a bad one.
In Shoemaker’s breakout 2014 season he hit a high of 118 (18% better than average). He was last above average (103) in 2016.
