Burnett's adjustment on the mound

After yesterday's game, the Star Ledger's Marc Carig noted on Twitter that A.J. Burnett had shifted towards the third base side of the rubber in order to get a better angle to the plate.  The chart below, with "release" indicating the location of the ball at 50 feet from home plate, confirms this:

Only 2011 home games were used in order to limit the amount of park calibration variation.  You can see that his most recent start is a big horizontal release outlier, as he's shifted about a foot towards third base (or "negatively," since this is from the catcher's perspective) from where he usually is.
