Derek Jeter

Baseball, New York Yankees. Jeter was named Yankees captain in 2003, the first since Don Mattingly, and held the role until he retired in 2014, winning the 2009 World Series in it on top of four earlier titles. Baseball captaincy is largely symbolic, so his leadership was mostly a matter of conduct: a calm, consistent public presence over two decades with one club in the most media-heavy market in the sport.
