On Tuesday, seemingly out of the blue, the Yankees dealt backup outfielder Mike Tauchman to the Giants for the left-handed reliever Wandy Peralta, in addition to a player to be named later. At first, it might seem odd that the Yankees would choose to marginally add to their greatest strength at the expense of their greatest weakness.
To date, no team other than the Yankees has gotten more than 1.6 fWAR from their relief corps, while the Yankees have already cleared two wins of value. The current iteration of the Yankee bullpen is already fairly loaded, especially considering the fact that they’ve been this good without their second-best arm, Zack Britton, who will miss at least the first half of the season.
