Venus Williams rolled back the years to produce a brilliant display as she eliminated fellow American Peyton Stearns 6-3, 6-4 to reach the round of 16 of the DC Open.

The only older woman to win a tour-level singles match was Martina Navratilova, whose last triumph came at 47 in 2004.

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.
