That's my prediction for the men's final at the U.S. Open Tennis Championships.
Women's Final
For the Women's Final I expect Serena to win but can't predict what Osaka might do to get past her. If I were to give her advice I'd suggest not to outpower her but rather play cat and mouse with spins and off speed action. The big question is if she can get Serena's serve back and also whether she can add enough variation on her serve to prevent Serena from attacking as she always does. It rarely works to try out hitting Serena.
