What our Post expert thinks about the U.S. Open

It would be quite the story if Osaka and Anisimova both advance to the semifinals.

Anisimova put together quite the redemption arc with her run at Wimbledon, but she came up short in the finals against Swiatek.

A trip to the semis at the U.S. Open would help ease the pain from that defeat.
