MELBOURNE, Australia - Unseeded Danielle Collins needed just 56 minutes to pull off the biggest upset in the Australian Open women's draw so far.
The two-time NCAA collegiate champion surrendered just two games to defeat No.2 seed and former champion Angelique Kerber to reach her first-ever Grand Slam quarterfinal, 6-0, 6-2.
"I played her last year, so I was familiar with her game. I had a clear mindset of what I was going to do. From the very first point, I showed her that I wasn't going to let her into the match, that I was going to dictate the entire way through," Collins said.
"I stuck to my game plan. It clearly worked out well for me. Pretty much smooth sailing throughout the entire thing. I was just feeling really great."
Before arriving in Melbourne, Collins had yet to win a Grand Slam match in five previous main draw appearances, but the stunning upset against the three-time Grand Slam champion was her third win over a seeded player so far this fortnight.
The World No.35 broke the 2016 Australian Open champion to love in the first game of the match, setting the tone early in a 20-minute opening set bagel where she hit 13 winners to just five unforced errors.
Her sizzling form continued over the next eight games as well, as she broke the German three more times in the second set, and finished the match with a whopping 29 winners to just 17 unforced.
Kerber hadn't lost serve in her first three matches of the fortnight, but ultimately held serve just once against the American's onslaught over the course of the match.
"It was completely not my day. I was not playing the tennis that I can play. She played really well," Kerber said.
"I think she played one of her best matches, to be honest. She hit every ball in the court. She moves good. For me, it was not my day, not my good tennis, but credit to her, she played a good match.
"She hit every ball on the line, in the court. I was just trying, I couldn't find my rhythm. The whole match, I was trying everything. I was trying to finding it. I was trying to fighting even in the second set and tried my best, but I couldn't find my rhythm and I was not able to play actually this tennis that I played the last days."
Already into uncharted waters in her first-ever Australian Open main draw, Collins will next face compatriot and No.5 seed Sloane Stephens, or unseeded Russian Anastasia Pavlyuchenkova for a place in the semifinals.
"I had some tough situations last year where maybe I didn't get past the first round. Let's face it, I played Wozniacki first round at the French. I played Mertens first round at Wimbledon. Sabalenka first round at the US Open," Collins said.
"I lost to really good players. I had some opportunities in those matches to maybe have a different outcome. You're not going to bring your best tennis every day. I did everything I could in those situations. Sometimes, it just doesn't go the way you want it to.
"Everybody gets their shot at the pie. Right now, I'm certainly getting mine. I'm doing very well. I'm just kind of focused on that."
