Serena Williams clinched her 300th Grand Slam victory, as she saw off Germany's Annika Beck 6-3 6-0, to qualify for the Wimbledon fourth round.
The defending champion's new milestone, moves her one position above Chris Evert into second place in the all-time list. Only Martina Navratilova's Open era record of 306 wins is ahead of her.
It also ensured that she is still on course, to equal Steffi Graf's Open era record of 22 Grand Slam titles, with her seventh Wimbledon crown.
"Oh, was it? Cool. Oh, nice. I had no idea. That's awesome, right? I think that's a lot of matches. It's a lot of wins," Williams said when told of her landmark.
"I thought it was good. I still want to get out to a little bit of a faster start but I was really focused and calm.
"Obviously, I love having that Sunday off but I'm a little behind in my matches so I guess I had to play an extra day."
