Following the 2011 season, A.J. Burnett wasn’t looking so hot. Three years into a five-year deal signed prior to the Yankees’ 2009 World Series-winning campaign, Burnett had provided the Yankees with 584 innings of 4.79 ERA (92 ERA+) and a K/BB ratio under 2.0. With two years and $33 million remaining on the deal, Burnett was shipped out to Pittsburgh for minor leaguers Exicardo Cayones and Diego Moreno and 60 cents on the dollar (New York paid $20 million of the remainder).
It was there, in Pittsburgh, that Burnett turned things around. In 393.1 innings, Burnett provided the Bucs with a 3.41 ERA (107 ERA+) and a K/BB ratio of 3.02. What’s more, his home run rate was drastically reduced, going from 81 allowed in those 584 Yankee innings (1.2 per 9) to 29 in 393.1 (or 0.7 per 9).
