The Latest: No. 1 Barty starts ‘Manic Monday’ at Wimbledon

WIMBLEDON, England (AP) — The Latest at Wimbledon (all times local):

11:10 a.m.

Play is under way on the busiest day in Grand Slam tennis: Wimbledon’s so-called “Manic Monday.”

No. 1 Ash Barty is in action against 55th-ranked American Alison Riske on No. 2 Court in one of four women’s singles matches currently in progress.

All 16 men’s and women’s fourth-round matches are on the program to begin Week 2. This is the only major tournament that schedules the middle Sunday off — and then the only one to play every singles match the following day.

Coco Gauff, Serena Williams and the men’s Big Three are slated to play later Monday.
