WATCH—The Hit: What keeps Venus Williams going?

MIAMI GARDENS, Fla.—Venus Williams had a respectable performance once again, reaching the round of 16 at the Miami Open, where she lost a one-sided match to Simona Halep.

The seven-time Grand Slam champion is still going strong at 38, but hasn't won a title since 2016. She reached three finals in 2017 (notably including two Grand Slams), but hasn't appeared in a final since Singapore at the end of that year. Currently ranked No. 48, she reached the quarterfinals in Auckland and Indian Wells, and lost in the third round in Melbourne, also to Halep.

Williams has said she wants to play in Tokyo for the 2020 Olympic Games, which isn't that far away anymore. While it's incredible to see Williams still on the tour this deep into her career, it's hard not to wonder: What's the point if she's not contending for titles?
