Andy Murray and Thanasi Kokkinakis produced one of the craziest rallies you're likely to see in a long, long time.
The pair played out one of the best matches of the Australian Open so far, a contest which finished at 4:05am.
But among the elite-level tennis that was on display, one moment - in particular - stood out.
Early on in the clash, it was hometown hero Kokkinakis who was taking control of proceedings, leading two sets to love at one point.
But one absolutely insane rally in the third set perhaps swayed the momentum in Murray's favour, arguably leading to his famous victory.
Thanks to an inch-perfect serve, the Aussie began dictating play and was making the Brit run all over the court.
But Sir Andy, showing not just impressive cardio but even more spectacular resilience, refused to give up.
Running from one side of the court to the other, he somehow managed to return his shots, letting out a groan as he lunged for each effort.
Kokkinakis' powerful shots were all landing right in the corners, but Murray was managing to dig deep and get to them back over the net.
This happened four or five times in a row, the four-time Grand Slam champ holding on for dear life.
After returning what was essentially a serve, Murray began getting in his groove and started picking his shots, managing to put Kokkinakis on the back foot now.
Clearly knackered as well, Kokkinakis' final shot just didn't have the legs and it hit the net before landing on the wrong side of the court.
Murray roared to the crowd as he celebrated the point.
The spectators in attendance were heard cheering loudly, clearly fired up over the overall rally itself as well as Murray's individual efforts.
When the Australian Open posted the clip to social media, it instantly exploded and started racking up millions of views.
On Instagram, one person commented: "Vintage Murray."
While another added: "Nobody has anticipation skills like Andy. Nobody."
The duo went on to play a five-set, 5-hour-45-minute thriller with Murray eventually coming out on top.
