Michael Zheng has pulled off one of the most remarkable upsets in Grand Slam history, and it's a story that's absolutely brilliant.
The 21-year-old Columbia University student stunned former Australian Open quarter-finalist Seb Korda in the first round at Melbourne, battling through five thrilling sets to claim victory.
What makes this even more impressive? Zheng wasn't even supposed to be in the main draw.
The psychology student had to fight his way through three qualifying matches just to earn his spot in the tournament proper.
It's the kind of underdog tale tennis fans absolutely love.
Here's where the story takes a frustrating turn for Zheng, though.
Despite earning £75,000 in prize money for navigating qualifying and reaching the second round, the American student is barred from keeping it.

NCAA regulations prevent college athletes from pocketing more than £5,000 annually from tournament winnings while they're still enrolled at university.
It's a rule that feels particularly harsh given the magnitude of what Zheng has just achieved on one of tennis's biggest stages.
Behind the scenes, there are growing calls for tennis authorities to revisit these prize money regulations that affect student players competing at the highest level.

Five facts for tennis fans | GETTY/PAZheng himself seems to be taking the prize money situation in his stride, though he's clearly keen to explore his options.
"I feel like it's gotten blurrier than it used to be in some ways in terms of the line between turning pro and staying in college," he said after his victory.
The American confirmed he's committed to completing his studies: "I still have one more semester at Columbia, which I do intend to finish.
"So whenever my run here is done, I'm going back to school."

He added: "I'll talk to our head coach, try to figure out what's the deal with the prize money, if I'm allowed to take it or not."
Zheng has also heard whispers that he might be able to claim the money since it's his final spring semester, but he wants to double-check before risking his eligibility.
"I want to make sure there's nothing wrong with eligibility if I take it. I don't want to get in trouble or anything," he explained.
The young American made history last November when he became the first player since Steve Johnson to win back-to-back NCAA championships.
His Melbourne adventure isn't over yet either – Zheng will next face French player Corentin Moutet in the second round, where another upset could be on the cards.
