From the Star-Ledger:

Jorge Posada seemed amused at the thought: Of all the players who have donned the pinstripes in the last 73 years, it was Posada who became the first to hit a grand slam in back-to-back games. The last Yankee to do it, way back in 1937?

“Bill Dickey,” Posada said today, following the Yankees’ 9-5 triumph over the Houston Astros at Yankee Stadium. “Another catcher.”

“You gonna get rid of that?”
