NEW YORK -- With an eye toward adapting to the National League rules later in the World Series, the Yankees made two changes to their official roster on Wednesday, reinstating Eric Hinske to their bench and adding Brian Bruney to the bullpen.

New York dropped third catcher Francisco Cervelli and pinch-runner Freddy Guzman from the 25-man squad that helped them advance past the Angels in the six-game American League Championship Series.

"Obviously, when we get to the National League city, pinch-hitters are going to be important, and by adding Hinske, we felt that we added another pinch-hitter," Yankees manager Joe Girardi said. "And the other thing is in the National League, sometimes there's more pitching changes because you have to hit for them, so we thought it was important to add another pitcher."

Cervelli not being carried as a third catcher could mean that the Yankees will not keep the battery of A.J. Burnett and Jose Molina intact for Game 2 of the World Series on Thursday, but Girardi wasn't tipping his hand in either direction.

"It's something that we'll discuss," Girardi said. "As I've said all along, it's worked pretty well. During the course of the season, you go with two catchers. Depending on what we do, I'm still comfortable using Molina."

Molina has caught Burnett's three postseason starts, but the right-hander allowed four runs in the first inning of Game 5 in Anaheim, with Posada entering the game in the fifth inning.

Hinske was on the roster for New York's three-game sweep of the Twins in the AL Division Series, but did not appear. He is making his third consecutive World Series roster, having also appeared with the Red Sox in 2007 and the Rays in '08.

He could be a valuable pinch-hitting option, particularly in the games at Citizens Bank Park, Girardi said.

"He's pinch-hit before," Girardi said. "It was an easy choice. Right now, I don't [see Hinske starting games], but we evaluate every day."

Bruney had been on a Yankees "taxi squad" in Tampa, Fla., for the first two rounds, continuing to throw in the event of injury before joining the club in Anaheim. He threw a simulated game at Yankee Stadium on Tuesday against teammates.

"We asked the guys to stay sharp, and we did everything we could to keep him sharp," Girardi said. "He threw yesterday against hitters and looked good. We kept him going. I think you'd expect him to do his job."

With Girardi saying Bruney "could do a lot of things," he gives New York 12 pitchers to face Philadelphia, which could come in handy if the Yankees follow their plan of using CC Sabathia on short rest twice in a potential seven-game series, and they may be considering using Burnett or Andy Pettitte on short rest.

The Yankees also may use Chad Gaudin as a fourth starter, which shifts Alfredo Aceves into more of a long-relief role for Games 1 and 2.

Guzman appeared twice in the ALCS, pinch-running in the ninth inning of Game 2 and remaining in the game, striking out in his only at-bat. Guzman also pinch-ran for Alex Rodriguez in the ninth inning of Game 5, but was stranded.

New York will continue to lean on Brett Gardner as their primary pinch-runner, while Jerry Hairston Jr. could also see some pinch-running duty. Girardi also reiterated on Wednesday that Hideki Matsui may see outfield duty after an emergency double-switch during the games in Philadelphia.
