In the first set, the 26-year-old Italian, playing in her first Grand Slam quarterfinals, had Williams scrambling after her lightning-quick serves and almost knocked her off of her feet with one that notched 118 miles per hour.
The upsets continued at 2018 Wimbledon with the last top seed falling as seventh seed Karolina Pliskova was sent packing by 20th seed Kiki Bertens, the Dutchwoman prevailing 6-3, 7-6 (1) to open up play on Court 2.
"To really share this feeling with her (Kerber), with a nation, I think that's something which is pretty special, " she said.
The action has continued from the Wimbledon quarter-finals with Germany's Julia Goerges beating a close friend to make the first semi-final of her career, while Juan Martin del Potro resumed his rain-interrupted match to set up a showdown with Rafael Nadal.
"Every time I play Giorgi, she always plays that level", Williams told the BBC.

Yes, no matter what the rankings or seedings say, no matter how long she was away, Williams still looks capable of playing like someone who's No. 1, just about 10 months after having a baby.

Serena Williams and her daughter Alexis Olympia watch the action during the first round of the 2018 Fed Cup at US Cellular Center on February 10, 2018 in Asheville, North Carolina.
Having shaken off the rust following her lengthy lay-off after the complications with Olympia's birth, Serena is on the verge of a 10th Wimbledon final appearance and 30th in all four Grand Slams. German made six breaks and lost four games on his serve.
"I feel like I'm getting to where I want to be", Williams said. Camila served brilliantly to reduce the tally but the Serena's unrelenting attack sustained the gap to 5-3. Winning the first break to go 4-2 up, she then held off three break points in her next service game, before serving out for the set in her next one. For me, there's so much further I want to go to get back where I was, and hopefully, go beyond that.
Williams is the big favorite to win an eighth Wimbledon title with all of the top-10 seeded women already knocked out. Williams has more wins in a major after losing a first set (39) than any other player in the women's Open era (Chris Evert has 28 and Venus Williams has 27). "I went for it", Serena said. However, the 13th seed has proved she knows how to win a close match.
Shocks decimated the women's draw early on but there is no real surprise that three of the players in Thursday's semi-finals are Grand Slam champions. "It's an honour to share the court with her", Goerges said after booking her last-four spot.
