If you were told that the four still standing are Timbo, TGO, Nasty Naz and the Golden Child, you'd be forgiven for thinking that the event in question is WWE's Royal Rumble or maybe skateboarding or high-stakes poker.
In fact, it's handball - the oneills.com World Wallball Championships to be exact.
Wallball, formerly called One Wall, is the fastest growing form of handball and this week's first standalone Wallball World Championships attracted almost 900 entries to the University of Limerick, with players from Ireland, the USA, Canada, France, Japan and the Basque Country among other nations.
But the Mecca of Wallball is New York, where there are over 2,000 public courts and it is a street game. The big names are known in every park in the city and many are effectively professionals, living off cash tournaments, large side-bets and endorsements.
One of those is Timothy 'Timbo' Gonzalez, a Red Bull-sponsored athlete who has trained with NBA legend Blake Griffin.
Yesterday, Timbo defeated Basque number one Lur Ziarrusta to advance to the semi-finals of the Open Singles, where he will meet Tywan 'Golden Child' Cook, a flamboyant New Yorker who has been improving as the tournament has gone on.
In the other semi-final, Irish hopes rest on Conor McElduff, who explained his TGO moniker ("The Great One") in an interview with the Irish Times last Friday.
The Tyrone right-hander takes on the form player, Nazir 'Nasty Naz' Marston. Naz put in the performance of the week yesterday in defeating UK number one Luke Thomson, a left-hander whose day job is head of recruitment strategy with Chelsea FC (as he told Declan Bogue in this interview on The42.ie).
Marston saw off Thomson 21-20, 21-9 in a stunning display and reckons that when he is on his game, nobody can beat him.
In the Ladies Open, there was disaster for Cork's Catriona Casey, the number one female player in the world, when she was forced to forfeit yesterday due to a nasty knee injury.
The semi-final line-up is all Irish, with Martina McMahon, Fiona Tully, Eilise McCrory and Caliosa Ní Dhúill all hunting for glory.
All four semi-finals will be live streamed on the Sport TG4 YouTube channel, starting at 3pm today.
