Rei Sakamoto faces Frances Tiafoe in the US Open round of 64 on hard. Frances Tiafoe is the paper favourite — ranked #12, defending last year's round of 32, a roughly 270-point hard Elo advantage — but Rei Sakamoto rides a 5-match win streak. Recent hard form is closely matched.
“I think Frances, if he is playing to the level he was in Cincinnati, he was playing really well.”
