AUCKLAND, New Zealand – It’s a good thing Daniel Kelly isn’t offended by the odds at the sports books. In fact, they can be quite humorous.

For a perpetually underestimated 39-year-old middleweight contender who keeps finding ways to win – one who was an underdog for each bout in his current four-fight winning streak – all he can do is laugh.

“It doesn’t bother me at all, and the good thing is – because I’m fighting better guys every time – that’s how it’s going to be,” Kelly told MMAjunkie. “But I’m what, -300 or -350 – a 3-1 underdog? I don’t care. It just means I’m fighting better guys, and that’s how it’s going to be.”

Actually, Kelly (13-1 MMA, 6-1 UFC) isn’t quite that big of an underdog to Derek Brunson (16-5 MMA, 7-3 UFC), whom he meets in Saturday’s UFC Fight Night 110 co-headliner. The bout airs on FS1 from Spark Arena in Auckland, New Zealand – a short jaunt from Kelly’s Melbourne home. Currently, Brunson is about a -270 favorite (a bettor would have to wager $270 to net $100 in profit) over +210 underdog Kelly (a winning $100 bet on Kelly would net $210 in profit).

Kelly is currently just outside the top 15 and is an honorable mention in the USA TODAY Sports/MMAjunkie MMA middleweight rankings following upsets of Rashad Evans (a -265 favorite), Chris Camozzi (-240), Antonio Carlos Junior (-500) and Steve Montgomery (-300). In the official UFC rankings, Kelly is No. 15.

A four-time Olympian in judo, Kelly isn’t necessarily surprised that he’s flown under the radar since joining the UFC via “The Ultimate Fighter Nations: Canada vs. Australia” in 2014. He’s not necessarily offended either. He knows he’s not the most intimidating 185-pounder on the UFC roster, but he also knows that if he can survive the first two minutes of a fight, “I match up well against anyone.”

So how does he keep doing it?

“I don’t know that I’m some kind of special athlete,” he said. “I think it’s just stubbornness that keeps dragging me along.”
