Dellin Betances

Baseball-reference

After posting solid numbers from 2014-2016, Dellin Betances took a step back in 2017. Betances walked 6.64 batters per 9 innings last season, nearly triple the 2.40 BB/9 he posted in 2014. Despite the high walks, Betances was still tough on batters, with a K/9 of 15.08. At times last year, it seemed like Betances was overthrowing the ball, perhaps trying to emulate Aroldis Chapman. The Yankees will be hoping for Betances to return to form in 2018.
