NEW YORK – Joba Chamberlain was activated from the disabled list Tuesday by the New York Yankees, and injured infielders Mark Teixeira and Kevin Youkilis might not be far behind.

Chamberlain was back in the bullpen for the second Subway Series game against the New York Mets after missing a month with a strained muscle on his right side. To make room on the roster, left-hander David Huff was designated for assignment.

Teixeira and Youkilis both got five at-bats Tuesday during an extended spring training game in Florida, then headed out to begin their rehab assignments Wednesday with Double-A Trenton. Yankees Manager Joe Girardi said it’s possible both could be ready to rejoin the team after two games in Trenton.

That would make them available for the start of a three-game series against rival Boston that begins Friday.

n Yankees closer Mariano Rivera was honored by the Mets and FDNY before his final scheduled visit to Citi Field.

Rivera, who plans to retire after this season, also accepted an invitation from the Mets to throw out a ceremonial first pitch before Tuesday night’s game.
