American trio Simone Biles, Megan Rapinoe and Tiger Woods are among the six nominees for the BBC Sports Personality of the Year's World Sport Star of the Year.

The results for both categories will be revealed on the night of the live BBC Sport Personality of the Year 2019 in Aberdeen on December 15.
