Only 11 other players who have called the Bronx home can claim that accomplishment.
"That's unbelievable," fellow backstop Francisco Cervelli said. "Every catcher wants to do the same thing. Everybody has a special ability, and he can hit, man. He can hit."
"The dude hits," starter A.J. Burnett said more succinctly.
Posada is just as aware of his position in catching history as his one in Yankees lore. He was quick to rattle off the other catchers whose company he joined.
"Bench, Fisk, Carter, Pudge," he said. "Three-hundred fifty doubles, 250 home runs, 1,000 RBIs. There's only five. It's a special accomplishment. I'm happy."
Posada joined teammate Derek Jeter (1,113) as one of two active Yanks with more than 1,000 RBIs. He is one of three Yankees catchers to reach that mark, along with Yogi Berra (1,430) and Bill Dickey (1,209).
Whereas other catchers have switched positions as their offensive production declined in their older years, Posada has embraced the challenge of succeeding at the plate while still defending behind it.
"You're banged up every day, and there's a lot of things that can happen," he said. "It's a tough position, but I'm happy that I'm there."
Posada is one of 24 active players with 1,000 RBIs. He's only the second catcher on that list, behind Ivan Rodriguez (1,292). Posada reached the plateau in his 1,660th game as a Yankee.
Lou Gehrig is the club's all-time leader with 1,995 RBIs.
