Fast forward to 2022, tiafoe just beat Rafa nadal in us open, crazy to see how much he has improved

[@RTFXTutorials]

Fast forward a few years, and Tiafoe has played in the Laver Cup and played doubles with Serena Williams. Crazy

[@AznSL]

What a beast...

[@Roadrunner65553]

Damn what ever happened to Stefan Kozlov?

[@johnnyblackrants7625]

Damn he has all the same mannerisms, but man I guess he started training once he got on the tour. He went from a boy's body here to a man's body now.

[@sludge86]
