Iga Swiatek extended her winning streak to a record 36th match with a straight-set victory over qualifier Jana Fett in the Wimbledon first round.
The world number one, who overtook Venus Williams' record for the longest streak by a women's player in the 21st century, beat the Croat 6-0 6-3.
Swiatek, in her first match since her French Open win, was not at her best in blustery conditions on Centre Court.
"I'm just figuring out how to play," the 21-year-old Pole said.
It was Swiatek's first match on grass this season after she opted not to play any warm-up events before Wimbledon.
"I knew it was going to be tricky. I am pretty happy I came back and did it in two sets," she said in her on-court interview.
I feel I have only played 12 weeks of my life on grass but the whole atmosphere and tradition is pumping me up and just looking forward to the next matches."
Swiatek had been picked to open proceedings on Centre Court on Tuesday - an honour given to the reigning
women's champion but handed to the Pole because Australian Ashleigh Barty retired earlier this year.
The two-time Grand Slam champion has dominated the WTA Tour this year and is aiming to win her seventh tournament in a row.
