Tennis great Serena Williams is one of the most accomplished athletes of the 21st century. She won 23 Grand Slam singles titles during her prolific career, which is just one shy of the women's tennis all-time record.

She retired after the 2022 US Open, citing her desire to spend more time with family and focus on other ventures. Her docuseries "In the Arena: Serena Williams" premiered at this year's Tribeca Festival in New York City.

At one point during the festival, the tennis champion was asked whether she had any thoughts she was willing to share about a fellow female athlete — Caitlin Clark.

Williams advised the WNBA rookie to keep "doing what she's doing."

"I just love that she tried to stay grounded and that she doesn't ... look at her social [media]," Williams told The Associated Press on the red carpet. "I get it. I don't either. And I think it's so important to continue doing what she's doing."

Williams also suggested that some of the negativity directed at Clark stemmed from jealousy.

"And no matter what other people do, if people are negative then it's because they can't do what you do … basically," Williams noted. "And hopefully she'll continue to do what she's doing."

Clark's name has been featured in countless sports headlines throughout the first several weeks of her first season in the WNBA. 

Much of the conversation about Clark has centered around the level of physicality the rookie has faced during her first handful of professional basketball games. 

"I think everybody is physical with me. They get away with things that probably other people don't get away with," Clark said on May 28 after the Fever dropped a game to the Los Angeles Sparks.

Earlier this week, Clark learned that she would not be traveling to Paris next month to play with the US women's national basketball team in the Olympics.

Diana Taurasi, Kahleah Copper, A’Ja Wilson, Chelsea Gray, Breanna Stewart, Brittney Griner, Alyssa Thomas, Napheesa Collier, Jewell Loyd, Kelsey Plum, Jackie Young and Sabrina Ionescu make up the 12-woman roster.
