One of the faces of the rivalry between the Red Sox and Yankees is calling it quits.
Yankees catcher Jorge Posada is planning to retire, according to an ESPN report.
The report says that Posada, 40, is expected to make the announcement in the next two weeks.
Posada was part of the "Core Four," along with shortstop Derek Jeter, closer Mariano Rivera and pitcher Andy Pettitte, helping the Yankees win five World Series championships between 1996-2009.
Posada lost his catching job before the start of last season and did not hit well when he moved to become a designated hitter. A switch-hitter, he was batting .165 against lefties on May 14 when he was dropped to No. 9 in the batting order and asked out of the game against Boston.
He finished the season hitting .235 with 14 home runs and 44 RBI. He then hit .429 in the five-game division playoffs series loss against Detroit.
Posada will finish his career with 275 home runs and 1,065 RBI. He was a five-time All-Star.
