Serena Williams raced into her 13th Wimbledon quarter-final as the seven-time champion thrashed Russian qualifier Evgeniya Rodina 6-2, 6-2 in just 62 minutes on Monday.
Williams, who won the Wimbledon title on her last two visits in 2015 and 2016, is now on an 18-match winning streak at the All England Club.
Having missed Wimbledon last year while she prepared to have her first child in September, Serena is in pole position to win her first Grand Slam crown since becoming a mother.
The 36-year-old faces Italian world number 52 Camila Giorgi on Tuesday for a place in the semi-finals.
Asked if it was a flawless display, Serena admitted she is never satisfied.
"I'm a perfectionist. I always find something wrong," she said.
"It was an interesting match. She was hitting the ball well. That's why she got this far. It was a good win but it was tougher than the scoreline to be honest."
