The Centre Court crowd were treated to a high-octane, powerful match that culminated in arguably the best game of the entire Championships, the highlight coming at deuce with Kerber leading 6-5 and serving for the set.
The game also featured seven match points and one of the greatest drop shots from Kasatkina that you will likely see.
Kerber summed it up perfectly: "The whole match was really good. The last game shows how good we played both and how she was fighting until the end. They are the matches why we are here and why we are trying to playing our best."
Serena's quarterfinal win over Camila Giorgi will have been music to the ears of the seven-time Wimbledon champion, and there were a couple of famous artists cheering her on from the Centre Court crowd.
Rapper Drake and Justin Timberlake -- along with wife Jessica Biel -- were spotted on camera enjoying everything this Grand Slam had to offer, including a cheeky glass of Pimms or two.

Serena's selfie game on point
And fresh from dispatching Giorgi, Serena even had time to teach a fan how to take a proper selfie on Centre Court.
Murray on the mic
Andy Murray doing a brilliant job as a pundit on the BBC. Obviously done his homework, dropping in little stats here and there, while giving some valuable insight.— Tom Hamilton (@tomhamiltonespn) July 10, 2018
I never ever want Andy Murray to retire from tennis. But when he does he'll make one hell of a pundit. Great with stats and analysis. Also love how much he likes and follows the Women's Tour too. #bbctennis #wimbledon @BBCOne— James Matheson (@jj_matheson) July 10, 2018
I think @andy_murray is going to be an amazing pundit when he retires. Insightful, good humoured and intelligent interview regarding BOTH the @WTA & @ATPWorldTour in his chat with Sue & Tim @Wimbledon @BBCSport . Looking forward to the commentary tomorrow Andy :) #Wimbeldon— Dan Connolly (@danconnolly22) July 10, 2018

The impossible task?
Speaking of Del Po-Nadal, the Argentine had the media room in howls of laughter following the conclusion of his fourth-round victory over Gilles Simon.
During his media conference, Juan Martin Del Potro was asked how he will beat Rafael Nadal in the Wimbledon quarterfinals on Wednesday. His reply brought the house down: “I don’t know, is a tough question!” The Argentinian has overcome troublesome wrist injuries over the last two years to rise to a career-high world No. 4 ranking. Now he has his eyes on a first-ever grass-court win over No. 1 Nadal. “Everybody knows the favorites are Roger and Rafa,” he said. “But the other six players are fighting for that big goal, as well. It could be a surprise this year. You never know.”
In this very cool video, Chris Fowler gives an inside look into how the Wimbledon broadcast comes to life with a visit into ESPN's control room at SW19.
The tall guys
Here's a fun graphic from ESPN's Stats & Info team Definitely comparing the Golden State Warriors' "Hamptons Five" lineup to the tallest remaining men's quarterfinalists -- the heights stack up quite nicely.
