Place £10.00 on Bryson DeChambeau @ 11.00 = Potential profit of £100.00

Smarkets logo

Lay £9.18 on Bryson DeChambeau @ 12.00 = Potential liability of £100.98


Let’s have a look at our potential profit/loss for the possible outcomes…

DeChambeau wins+ £100.00– £100.98£0.98 loss
DeChambeau doesn’t win– £10.00+ £8.99£1.01 loss

So, no matter who wins, we’ll lose a maximum of £1.01 in qualifying for our potential free bets.

Free bets

We’ll receive a £1.00 free bet for every shot Bryson DeChambeau is under par in Round 1. Free bets will be credited within 24 hours and will be valid for 7 days on any sport.

If Bryson Dechambeau finishes Round 1 on 5-under-par (-5), we’ll receive £5.00 in free bets. Using straightforward matched betting, we should be able to convert our free bets into 80% cash, so £4.00.

If we take into account our minimum qualifying loss of £0.98, this gives us a potential profit of £3.02 on this NetBet offer!

* Bryson DeChambeau was 4-over-par (+4) after Round 1 and finished the tournament in a tie for 46th place, resulting in a loss of £1.01 on this NetBet offer. *
