He started at first base April 19, three days before he returned to catching, but he made it clear Sunday that he would not be shifted there again. Posada, 36, signed a four-year, $52.4 million contract last winter to be a catcher, and he said he intended to play that position for the length of the deal.

"I’m not playing first base," Posada said. "I’m a catcher. We’ve got seven first basemen."
