Through game of April 23, 2011, Jorge Posada (NYA) had collected nine hits, six of them for home runs. His batting average and OBP were low, but he was at least being somewhat productive with the long ball. He was only hitting right-handers, however, and they were challenging him over the plate:
Jorge could pound those pitches:
After his sixth home run, pitchers stopped visiting that part of the strike zone:
Once again, Posada collected nine hits in this time frame, but this time five were singles and none were home runs. Posada's ability to hit have declined so much that pitchers can avoid the center of the strike zone and still get him out. Without the power, Jorge is an extremely bad hitter. He was lucky the Yankees dropped him to ninth instead of benching him altogether.
