Navratilova holds the record for the oldest woman to win a singles match at a Grand Slam, which came at Wimbledon in 2004 when she was 47 years, eight months.
Date-Krumm’s best result at the Australian Open came in 1994 when she reached the semifinals. She achieved a career-high ranking of No. 4 in 1995.
She made her Grand Slam debut at the French Open in 1989 when Petrova was just 6 years old.
On Tuesday, Date-Krumm cruised through her match against 30-year-old Petrova in 64 minutes. She made 75 percent of her first serves, while Petrova stumbled with 38 unforced errors.
“She’s a tough cookie,” said Petrova, a 2010 quarterfinalist at Melbourne Park. “She played really well today. She didn’t give me any room to come back.”
Petrova agreed that a vacation from the sport that requires rigorous travel around the world could be a good thing.
“She took a 10-year break,” Petrova said, “so you know she might be fresher than most of us in our 30s.”
