Thank you Hailey for giving me the opportunity to prove not only to myself but the world I have something to offer the game of tennis that we all love. Our professional relationship has come to an end but I will still be your biggest supporter in every aspect of your life. Go team Baptiste 2026 is your season," Franklin Tiafoe on Instagram.

A quarterfinal at the French Open along with a runner-up finish in Houston were the only highlights of his season, which he capped off with a year-end ranking of No. 30. Tiafoe eventually shut down his season after the Shanghai Masters. He returned to action for a couple of exhibition events over the past week, and wound up winning both of them.Frances Tiafoe beat Carlos Alcaraz and Taylor Fritz to win the exhibitions in Newark and CharlotteFrances Tiafoe at A Racquet At The Rock.
