Last year the Yankees’ #4 starter was Joba Chamberlain. In a year that can only be described as a disappointment in his development (setting aside the World Series Championship and all), Joba posted a 4.75 ERA over 157 innings- good for a measly 1.5 wins above replacement. With CC, AJ, and Andy all back in the fold, Joba will be bumped by Javier Vazquez.

We’ve already given the thumb’s up to Javy’s second tour of duty, but it’s hard to understate the increase in value here. Vazquez is coming off a career year where he was worth 6.6 WAR. While he can’t be expected to scale those heights again, he was remarkably consistent in the three years prior: 4.8, 5.1, and 4.8 WAR. Javy reasonably projects to be a 2.5 win upgrade in the rotation for the Bombers.

That makes him the biggest upgrade of the offseason to date — for any team in baseball.

The trade for Vazquez was BIG.
