Among relievers with at least 150 innings of work over the past four seasons, Dellin Betances ranks in the top five in K/9, ERA, FIP, and WAR. In other words, Betances is undoubtedly one of MLB’s most dominant relief pitchers when healthy. Luckily for the Yankees, Betances should be back on the mound in time for the 2019 playoffs, assuming his rehab from a right lat strain doesn’t hit any more bumps in the road. There’s no question the Yankees are going to use Betances once he’s healthy, but Aaron Boone will have to decide where Betances fits into one of the league’s best bullpens.
