It's nearly go time for the fifth edition of The Match starring Brooks Koepka against Bryson DeChambeau.
The pair of high rollers will peg it up at the Wynn Golf Club not far from the blackjack, roulette and poker tables on the Las Vegas strip.
Depending on your thoughts, this will either be a few hours of tedious banter or light-hearted fun.

What about betting?
Bryson DeChambeau is the favourite. Just.

DeChambeau is priced at 10/13.
A hole-in-one for either player pays out at 50/1.

Who we are tipping?
The fact that this is only 12 holes makes this a bit more unpredictable. In our view, you just have to look at form. DeChambeau is the slightly better golfer as of right now and he has experience in this kind of event. We are backing DeChambeau.
What they said?
Koepka: "I think I've said it like 10 different times, I mean, I've never really liked him. He said that stuff to (my caddie) Rick and I just thought it was crap. You don't go ask my caddy to go say something to me; come find me. Don't be a little baby about it. I think he's learned his lesson."
DeChambeau: "This is all real from my end, at least. It's disgusting the way the guy has tried to knock me down. There's no need for it in the game of golf. He has been trying to knock me down at every angle, every avenue, every way. For what reason? I don't know. Maybe it's because he's jealous."
