Big-serving Ben Shelton apologised to fans after playing the role of party pooper and ending Dane Sweeny's Australian Open odyssey at Melbourne Park.
The eighth-seeded Shelton crunched 19 aces, the third-fastest serve of the tournament and never even offered up a single break point in ousting Sweeny 6-3 6-2 6-2 on Thursday.
Averaging an ace and a half every game and dropping only five points after landing his first delivery, Shelton barely gave the Australian underdog a look-in on John Cain Arena.
Despite never really standing a chance, Sweeny threw himself around the court and dived for volleys like vintage Boris Becker at the net in pursuit of another boilover after ending Gael Monfils' AO career in round one.
"Dane is a great competitor, a really tough guy to play. He's electric," Shelton said.
"It's clear why the Aussie crowds love him here and he's a fan favourite and I'm sure he's going to be lighting up John Cain (Arena) for many years to come.
"This is a court that I'm experienced playing on. I'm experienced playing Aussies here. I'm sorry about the outcome today, but I love the chants. I love the noise.
"I love the passion that you guys have for the sport. So thanks everybody for coming out today, even if you wanted me to go down."
Despite his exit, Sweeny will depart with a cheque for $225,000 after winning three matches to qualify, then claiming his maiden main-draw win at a slam.
The 24-year-old is also set to soar 34 spots up the rankings to a career-high No.148 in the world.
Shelton, meanwhile, marches on and next plays fellow Valetin Vacherot in the third round after Monaco's 30th seed eliminated Sweeny's fellow Australian Rinky Hijikata 6-1 6-3 4-6 6-2.
Two-time defending champion Jannik Sinner and 10-time Open king Novak Djokovic also cruised.
The fourth-seeded Djokovic spent just two hours and 15 minutes on court to wipe out Italian qualifier Francesco Maestrelli 6-3 6-3 6-2.
"I didn't know much about him until yesterday or a couple of days ago," Djokovic said.
"It happens more often than not these days for me. Nevertheless the respect is always there - I don't under-estimate anyone."
Next up for Djokovic in the 38-year-old Serb's ongoing quest for an unprecedented 25th grand slam singles crown is Dutchman Botic van de Zandschulp on Saturday.
Second-seeded Sinner eliminated Australian wildcard James Duckworth 6-1 6-4 6-2 in the night match on RLA, leaving Alex de Minaur as the last local hope in the men's singles for yet another year.
Fifth seed Lorenzo Musetti also advanced to the last 32 with a 6-3 6-4 6-4 win over fellow Italian Lorenzo Sonego.
Musetti will play newly-crowned Adelaide International winner Tomas Machac next after the Czech took out 11th-seeded 2023 Open finalist Stefanos Tsitsipas 6-4 3-6 7-6 (7-5) 7-6 (7-5).
American ninth seed Taylor Fritz continues to dispel lingering fitness concerns, advancing 6-1 6-4 7-6 (7-3) over Czech Vit Kopriva.
Fritz will play 2014 champion Stan Wawrinka for a fourth-round berth after the 40-year-old retiring Swiss great defied the odds again with a 4-6 6-3 3-6 7-5 7-6 (10-3) win that stretched four hours and 33 minutes.
