Jessica knocks out champ Madison

JESSICA Pegula was driven by extra motivation in her fourth-round win over defending Australian Open champion Madison Keys - avoiding wearing a Kansas City Chiefs jersey.

Pegula and Keys are close friends away from the court and present The Player’s Box podcast together along with fellow American players Jennifer Brady and Desirae Krawczyk.

The pair agreed that the winner of the clash would get to choose a forfeit for the loser and, had Keys won, Pegula, whose parents own the Buffalo Bills, would have had to don a Travis Kelce/Taylor Swift Chiefs jersey.

“That was bad,” said Pegula. “She was, like, ‘Mine’s worse’ I was, like, “What are you talking about? My family owns the Bills. This team has owned us in the postseason.”

“All she has to do is eat a piece of pie. What is the big deal? I think that was really some extra motivation, because that would have been a tough moment for me.”

The pie in question is the Pegula family's Thanksgiving tradition of apple pie with melted cheddar cheese on top.

“A bet is a bet, so I'll do it,’ said Keys. “I hope it’s less gross than I think it’s going to be, but we will find out, I guess.”
