Roger Clemens was one of the most successful Pitchers of all-time, and the legend of the "Rocket" began in Boston, where he was a must-watch attraction at Fenway.
Carl Yastrzemski literally took over where Ted Williams left off as the premier hitter and Leftfielder for the Boston Red Sox. Like Williams, Yaz played his entire career with Boston and was unable to win a World Series Championship.
Were you expecting someone else?
As incredible as Ted Williams was, it is lost a bit, as to just how good he was. Part of this because so much time has passed; part because his Red Sox only won one American League Pennant.
