Saturday night's UFC 196 event certainly threw up more than its fair share of shocks as both fights topping the bill saw the underdog emerge victorious.
In what was a dramatic night of action in Las Vegas, Nate Diaz stunned the fighting world with a well-earned win over Conor McGregor, while Misha Tate grabbed the Women's title from Holly Holm.
McGregor and Holm were certainly heavy favourites with bookmakers to leave the MGM Grand with wins, but there were some brave individuals who wagered against the trend. For one man, that meant a $223,000 profit.

As reported by MMA Junkie, Dave Oancea came away with $300,000 thanks to Tate's fifth-round submission win. He had placed $77,000 on the 29-year-old fighter.
Oancea isn't your typical punter, however. Known as 'Vegas Dave', he is a professional gambler who has made a habit in recent times of coming up big when it comes to UFC.
This past weekend's huge win comes after netting a $220,000 profit back at UFC 193 courtesy of Holm's shock win over Ronda Rousey. Backing the underdog has certainly paid off recently.
What's more, due to his status within the fighting and gambling worlds, Tate was actually aware of Vegas Dave's bet before stepping into the Octagon on Saturday.
Speaking on MMA Junkie Radio in the lead up to her fight, the +250 underdog actually revealed Oancea had texted her with his wager.
They even celebrated their respective wins together after the bout had come to an end.
With several shock results over the past few months, UFC is certainly developing a reputation as one of the most unpredictable sports there is - and it is paying off for those with the bravery (and wallets) to back the less favoured fighters.
With Vegas Dave, so far at least, having only revealed his Tate bet it doesn't look like the pro gambler predicted the other major shock of UFC 196.
Night of upsets
In fact, there are probably very few people out there who did see the American's win over Conor McGregor coming.
Given such a short time to prepare for the fight, and McGregor's previous undefeated UFC status, there weren't many fans giving Diaz much of a shot before he forced the Irish star to submit.
Where the quartet of Tate, Holm, McGregor and Diaz go from here remains to be seen. What is certain, however, is that Vegas Dave will be keeping a close eye on any and all of the upcoming UFC events. With almost half a million dollars in profit in the past six months, you can't blame him.
