Though Serena Williams has said she wouldn’t be able to win a game if she played Andy Murray, the best female tennis player in the world is making the claim that she’s technically defeated every major men’s player of the past 20 years.

In a fun interview with former pro and current Fox Sports 1 analyst Andy Roddick, Serena drops the theory that because she defeated Roddick when they were both in elementary school, that means she’s able to claim victory against all the men Roddick defeated during his professional tennis career and, by extension, the men those men have beat.

“I’ve beaten Roger because I’ve beat you, I’ve beaten Rafael Nadal, I’ve beaten Pete Sampras,” Serena joked to Roddick. “You name them, I’ve beaten them, because I’ve beat you.”

Serena was 11 when she defeated a 10-year-old Roddick in a match in Florida. She jokingly calls it her “greatest match.” Using her theory, we’ve extrapolated how many victories Serena can claim. Her statement holds true. Witness:

Serena defeated Andy Roddick who defeated Pete Sampras who defeated Jimmy Connors who defeated Pancho Gonzalez who defeated Don Budge who defeated Bobby Riggs who defeated Margaret Court who defeated Billie Jean King who defeated Chris Evert who defeated Steffi Graf who defeated Venus Williams who defeated Serena Williams. It’s a timeline that spans 75 years and peripherally includes John McEnroe, Bjorn Borg, Martina Navratilova and every other major Grand Slam champion, which means that Serena has technically defeated every legend of the past three-quarters of a century, including herself.

Mind. Blown.
