Who is Peyton Stearns' ‘GOAT’? 

Peyton Stearns enters the Miami Open at a career-high ranking inside the Top 50, and though she’s been working with coach Tom Hill, who most notably coached Maria Sakkari to the top of women's tennis, for close to a year, Stearns confessed this week that there’s another support beam strengthening her game.

Mick Assaf, former running back for the University of Notre Dame, is the "greatest of all time" as far as the former Texas Longhorn is concerned, on and off the court.

Stearns' declaration came on social media as X, formerly Twitter, users gushed over a shirtless photo of Assaf on the practice court under the Miami sun.

"My 🐐🩷," she wrote, with a heart emoji.

Co-founder of NIL Club, Assaf is helping more 20,000 high school and collegiate teams monetize their game. According to the organization's website, more than $16 million has been earned by more than 250,000 participating athletes through its work.

Assaf has been by Stearns' side throughout the year on tour so far, and is now supporting the American in Miami, where Stearns hopes to reach the third round for the first time with a win over No. 27 seed Elise Mertens on Friday.

The Belgian’s win probability stands at 57%, not to mention that she won the only previous meeting a year ago at WTA 1000 Doha.
