Venus Williams made a triumphant return to singles tennis on Tuesday after a 16-month hiatus, defeating fellow American Peyton Stearns 6-3, 6-4 to reach the second round of the WTA and ATP DC Open.

The 45-year-old winner of seven career Grand Slam singles titles rolled to her 819th career WTA singles victory in 97 minutes at the first US Open hardcourt tuneup event.

"It is not easy to come off after all that time and play the perfect match," she said. "Peyton played so well. I felt like I was trying to slow myself down from going faster and faster and faster."
