Veterans in race against Tokyo time

SERENA WILLIAMS

The American tennis great will be 40 in September 2021 although her desire to play in Tokyo might not be as pressing as that of Federer.

Williams already has four Olympic gold medals－singles at London 2012 and doubles with sister Venus in 2000, 2008 and 2012.

The sisters lost their opening-round match at Rio 2016 while Serena's gold-medal defense in the singles was ended by Elina Svitolina in the third round.
