Vote now: Who should be SI's 2015 Sportsman of the Year?

Meet the 2015 SI Sportsperson of the Year candidates

Sports Illustrated managing editor Chris Stone and executive editor Jon Wertheim reveal the 12 candidates for SI Sportsperson of the Year and explain how they determined the contenders.

Sports Illustrated’s editors will choose the 2015 Sportsman of the Year, but we think our readers should also have a say. Cast your vote below for the person in sports (or, in Pharoah’s case, superhorse) you think embodied the spirit of sportsmanship and achievement this year. During the month, we'll also be publishing a series of essays from our writers and peers of the 12 contenders that make the argument for each candidate. Read more about each contender here.

Voting closes at 11:59 p.m. on Dec. 12 and the winner of our reader poll will be revealed on Dec. 13. Sports Illustrated’s Sportsman of the Year will be announced on Dec. 14. It's your chance to let us know who should take home SI's biggest honor for 2015.
