A spot in the next round is at stake on Wednesday, when Coco Gauff goes up against Elise Mertens in the Beijing round of 16. Coco Gauff is 9-1 across recent matches. Elise Mertens has won 7 of the last 10.

There's a wide gap in our ratings on hard, and our number follows from it. Gauff should have enough here, though Mertens has the tools to make the scoreboard uncomfortable.
