FILE – In this July 8, 2019, file photo, United States' Serena Williams returns the ball to Spain's Carla Suarez Navarro in a women's singles match during day seven of the Wimbledon Tennis Championships in London.  After the traditional middle Sunday off, Wimbledon would have resumed this week with what some consider the most exciting day of tennis: The second Monday, when all 16 men's and women's singles matches in the fourth round are scheduled. Of the 19 times Williams has entered Wimbledon, she reached Week 2 of the fortnight on 16 occasions; that includes seven of her 23 Grand Slam singles trophies and another four runner-up finishes, including in 2018 and 2019.
