A spot in the next round is at stake on Friday, when Carlos Alcaraz goes up against Yibing Wu in the US Open round of 32. Carlos Alcaraz is 7-3 across recent matches. Yibing Wu has won 3 of the last 10.

There's a wide gap in our ratings on hard, and our number follows from it. Anything other than a Alcaraz win would rank among the bigger surprises of the week.
