The Octopus against The Ironman. If the outcome of Daniil Medvedev versus Marton Fucsovics had been determined purely by muscle strength, there would have been a clear winner on No.1 Court.
But lawn tennis isn't body-building or cage-fighting and a wet day at Wimbledon was a good day for The Octopus, who reached the last 16 under a closed roof to equal his best result here.
Every day is apparently gym day for Fucsovics, who is probably best known for his shirt-off celebrations after winning a match at this year's Australian Open, revealing a sculpted look that wouldn't be out of place on the cover of Men's Health magazine.
Inevitably, that image went viral. With his long, tentacle-like limbs, Medvedev acknowledged in Melbourne that he couldn't compete with his Hungarian friend's muscles and after winning his next match he was in self-deprecating mood, pulling up the leg of his shorts to flex a skinny thigh.
Here in London the No.3 seed showed that, with his tall, sleek physique - he stands 6ft 6in before he even puts his grass court shoes on - he can strike the ball with pace on the lawns.
Beyond the might of his groundstrokes and the wallop of his serve, Medvedev was also showing his softer skills, his craft and touch, against the world No.67.
"That was a tough match. Marton plays well on grass - he has played in a quarter-final here, which I haven't done yet. I'm happy to get through as I have big motivation to do well," Medvedev said after coming from a set down for a 4-6, 6-3, 6-4, 6-4 victory.
The highlight of the opening set was Fucsovics' diving volley, which the crowd adored. That was the first set that Medvedev had lost all Fortnight.
It was a moment to remind yourself that Fucsovics had won their only previous Grand Slam match, in the opening round of Roland-Garros in 2020. But Medvedev wouldn't drop another set.
For the first time all season - and this seems like an odd thing to write about a former world No.1 and the 2021 US Open champion - Medvedev is through to the second week of a Grand Slam.
After going out in the third round of the Australian Open and a hugely dispiriting defeat to a qualifier in the first round of Roland-Garros, he has at last started to put a run together at the Grand Slams in 2023.
This has long been Medvedev's happy place. Now Wimbledon's bringing him even greater joy. Next Medvedev will have the opportunity to apply for membership of Wimbledon's Last Eight Club, which is reserved for anyone who reaches the quarter finals.
Medvedev plays Czech Jiri Lehecka or American No.16 seed Tommy Paul in the fourth round.
