Bullpen Diaries: Mariano Rivera, Bronx Dreams, Pinstripe Legends, and the Future of the New York Yankees

In his newest book, Rosen (More than a Game) follows the ups and down of the New York Yankees bullpen over the course of the 2010 season, focusing on game recaps in which he evaluates how each reliever performed. He gives a solid overview of the scouting system used by Major League teams to rate and scout pitchers, and interviews players and coach. Rosen's affection for the sport is infections, though by focusing specifically on what happened when the relievers were pitching makes his narrative feel incomplete. Also many of the conversations with or about the players revolve around stock answers about the pitching mechanics of arm action and foot placement so that readers get little insight into each pitcher, except for minor leaguer Jason Hirsh. His narrative is highlighted by charming personal pieces titled "Memory Lane," in which he recounts his life growing up a Yankee fan, as well as offering fun, historical facts that bring the game to life.
