Defending champion Serena Williams did not need to work too hard to earn her 300th career Grand Slam match win and move into the fourth round at Wimbledon, overwhelming 43rd-ranked Annika Beck of Germany 6-3, 6-0.
It took all of 51 minutes at Centre Court on Sunday.
Williams seemed surprised after the match, telling reporters she had "no idea" that she reached the milestone.
"Cool, oh, nice. I had no idea. That's awesome, right? That's a lot of matches," Williams said.
Williams, who has won six of her 21 Grand Slam titles at the All England Club, compiled a 25-2 edge in winners.
After falling behind 2-1 at the outset against Beck, Williams won 11 of the last 12 games and 24 of the second set's 28 points.
The No. 1-ranked Williams improved to 300-42 at major tournaments. That breaks a tie at 299 wins with Chris Evert and now ranks second in the Open era to Martina Navratilova, who went 306-49.
