Feb. 8 (UPI) -- Serena and Venus Williams opened the 2021 Australian Open in dominant fashion on Monday, each delivering victories in straight sets in the tournament's opening round in Melbourne.
Venus, 40, beat Kirsten Flipkens 7-5, 6-2 at Margaret Court Arena. She fired three aces, 10 winners and won four break points. The seven-time Grand Slam champion defeated Flipkens in one hour and 32 minutes.
"I was happy just to get through it," Serena, who's won the tournament seven times, told reporters after the match. "I wasn't sure how my serve would be after a little bit of that shoulder [injury], but it's feeling good."
Venus, ranked No. 81 in the world and a two-time Australian Open winner, next faces Italian Sara Errani in the second round and Serena, 11th in the WTA rankings and the tournament's No. 10 seed, will battle Serbian Nina Stojanovic.
Djokovic is the defending men's singles champion and American Sofia Kenin, the No. 4 seed at this year's tournament, won the Australian Open a year ago.
The 2021 women's singles final is on Feb. 20. The men's singles final is scheduled for Feb. 21.
