Boasting a mix of homegrown talent and All-Star signings, the 2009 Yankees were composed of the very best. With the previous season's failed playoff bid still as fresh as the paint job on the new Yankee Stadium, a 27th championship flag represented the singular objective of a squad that ultimately carved out a unique spot among the Yankees' pantheon of World Series teams.

It was the last title for the "Core Four"--Derek Jeter, Mariano Rivera, Jorge Posada, and Andy Pettitte--who would each retire over the course of the next five years. It was the lone title for Alex Rodriguez, Mark Teixeira, A.J. Burnett, and Nick Swisher, each of whom saw memorable peaks and valleys during their time in the Bronx. For CC Sabathia and Brett Gardner, it was their first championship, though the veterans were still in pinstripes as the latest generation of Yankees arrived for what they hope will be the next dynasty. Mission 27 is a thoroughly reported chronicle of an unforgettable season, packed with interviews with the full cast of key players, team executives, broadcasters, and more.
