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.

Tennis legend Venus Williams is back. The 45-year-old former world No. 1 player won her first singles match in nearly two years, defeating the world No. 35 Peyton Stearns, 6-3, 6-4, to reach the second round of the DC Open.

Playing alongside Hailey Baptiste, who is nearly half her age at 23 years old, Williams beat Canada's Eugenie Bouchard and American teenager Clervie Ngounoue 6-3, 6-1 in the first round on Monday. Then on Tuesday, she stunned former NCAA champion Peyton Stearns, who is ranked 35th in the world, in a 6-3, 6-4 singles upset.
