Contest: An instructional book about baseball

Hey, I wrote yesterday, "Stop by later for a contest." Today is still "later," isn't it?

And now I'll give my copy to the first person who e-mails me - at kdavidoff@newsday.com - with the correct answer to this question:

The book features action shots of Ryan Braun, Derek Jeter and Albert Pujols on its cover. No player has ever been a teammate of all three superstars. One man, however, has played alongside Braun in Milwaukee and Pujols in St. Louis and is currently in Yankees camp with Jeter, although he's a longshot to make the Yankees.

Name this player.
