Venus Williams couldn't pull off another upset in Washington and exited the tournament in the round-of-16, while No. 1 seed Jessica Pegula picked up a shock loss in her opening match.

Venus Williams became the second-oldest woman to win a tour-level singles match in professional tennis, delivering some of her familiar big serves and groundstrokes at age 45 while beating Peyton Stearns — 22 years her junior — by a 6-3, 6-4 score at the DC Open on Tuesday night.
