What do Rube Walberg, Mike Nagy, Kevin Millar, and Dustin Pedroia all have in common? They all wore #15 for the Boston Red Sox. Since 1931, the Red Sox have issued 74 different numbers to more than 1,500 players. Red Sox by the Numbers tells the story of every Red Sox player since '31--from Bill Sweeney (the first Red Sox player to don #1) to J.T. Snow (#84, the highest-numbered non-coach in Sox history). Each chapter also features a fascinating sidebar that reveals which players were the most obscure to wear a certain number and also which numbers produced the most wins, home runs, and stolen bases in club history.
