June 30 (UPI) -- World No. 1 Aryna Sabalenka dominated Carson Branstine over 73 minutes while other elite tennis stars struggled to overcome record temperatures and upset-minded foes on Day 1 of Wimbledon 2025 on Monday in London.

Branstine totaled seven aces, compared to three for her Belarusian counterpart, but also logged 26 unforced errors. Sabalenka, who totaled 18 unforced errors, broke the No. 194 Canadian's serve three times in the 6-1, 7-5 victory.

"I'm super happy to be back, to be healthy and to compete at this beautiful tournament," Sabalenka, who withdrew early last year because of a shoulder injury, said in her on-court interview. "I was really depressed last year that I couldn't feel this atmosphere.
