Like most sports, MMA offers up a huge upset that few fans or handicappers expect to happen. Unlike most sports where big upsets are unusual, in the MMA, every fighter has a puncher's chance of winning. It makes betting UFC odds a fun and profitable outlet for smart sports bettors.
Here is a short list of some of the biggest upsets in UFC history, in order of moneyline payout.
Matt Serra vs. Georges St-Pierre
At one point Serra was a huge +700 underdog against then UFC Welterweight champ St-Pierre, who came with a price of -1100; Serra was coming off an impressive run on The Ultimate Fighter where he won the Season 4 Welterweight competition. No one gave him a chance against the champion but a well-timed punch stunned St-Pierre and led to a KO win for Serra. GSP would return a few months later and destroy Serra in the rematch.
Frank Edgar vs. B.J. Penn
Up-and-comer Edgar was a +650 underdog when he fought Penn for the UFC Lightweight title at UFC 112, but his combination of wrestling and boxing skills were more than the champion could handle. Penn had a price of -1100 but was unable to mount much of an attack and lost a unanimous decision. Edgar proved it was no fluke by dominating Penn again in the rematch, again as a big underdog.
Tito Ortiz vs. Ryan Bader
When Ortiz stepped into the Octagon to fight Bader (who was favored by as much as -825) most MMA fans and handicappers thought it would be the last time we saw The Huntington Beach Bad Boy fight in the UFC. However, a perfectly placed uppercut changed all of that and Tito paid out as much as +550 to his faithful betting fans.
Fabricio Werdum vs. Junior dos Santos
Finding action on a potential superstar before they have their coming-out party is some of the best MMA betting value you’ll ever find. Today dos Santos would not be a +500 underdog against Werdum, but at UFC 90 that’s what the upset line was and dos Santos went on to rock the -800 favored Werdum and win via first-round KO. And as they say, the rest is history.
Joe Lauzon vs. Melvin Guillard
Guillard was on a five-fight win streak and looked like he had finally developed to the point where he was ready for a title shot - all he had to do was get past Lauzon, who was handicapped as a +444 underdog. Guillard looked like easy money as the -615 favorite, but a timely left hook counter-punch rocked Guillard and gave Lauzon enough of a window to slap on a rear-naked choke in the first round for the win.
