LONDON, Great Britain - 23-time Grand Slam champion Serena Williams continued her march towards a possible eighth Wimbledon crown on Manic Monday, knocking out fellow mother Evgeniya Rodina, 6-2, 6-2 on Centre Court to reach the quarterfinals.

"I'm a perfectionist," she said during her off-court interview. "I always find something wrong. I thought it was a good scoreline, but it was tougher than the score, to be honest. She can really hit the ball well, and that's why she got so far. It was an interesting match, to say the least.

"There's a lot to improve on," she continued in press. "This is only my fourth tournament back. I would hope there's a lot to continue to improve on. There is. I feel like I'm getting to where I want to be. For me, there's so much farther I want to go to get back where I was, and hopefully go beyond that."

In a ladies' singles draw that featured six mothers at the start of the fortnight, Williams was taking on Rodina in the first-ever Grand Slam main draw match between mothers after the Russian upset No.10 seed Madison Keys in the third round. The former World No.1 wasted little time to make her 13th career last eight appearance at Wimbledon after 64 minutes on court.

"It's great. I knew that we were both moms. I'm not sure how often that's happened, if ever. It's cool that you can be a mom, play tennis, be great, and be in the quarterfinals of Wimbledon.

"You can be a working mom if that's what you choose. Stay-at-homes moms, dads, parents have full time jobs too! My mom raised five kids; I don't know how that's even possible because I'm struggling with one! Either way, women are empowering each other."

The American faced few problems in the opening set, and navigated through the lone break against her serve with relative ease, breaking straight back to clinch the match behind 30 winners to just 11 unforced errors.

Rodina, by contrast, struggled to find her range in her first Centre Court appearance of the fortnight, striking only five winners and 10 unforced errors throughout the clash.

Standing between Serena and the semifinals is big-hitting Italian Camila Giorgi, who reached her first major quarterfinal earlier in the day after defeating Rodina's countrywoman Ekaterina Makarova in straight sets.

"I played her a couple times. She has a very powerful game. To be so small, she brings so much power and energy on the court. She's very aggressive. She does well on grass.

"I do follow women's tennis. Of course I support women's tennis. I support women's sports. I follow so much of it. I think it's super exciting. I watch her play a lot. It's good to kind of know someone. A lot of the players I've played this tournament, I don't think I've played them before. I don't think so. It will be good. I kind of know her game. Look forward to it."

Serena and Giorgi last played in the first round of the 2016 Australian Open, where the seven-time Wimbledon champion increased their overall head-to-head to 3-0 in her favor.
