Randall Bailey (43-7, 37 KO) was a 37-year-old underdog with only one physical advantage over his 29-year-old undefeated foe: one-punch-knockout power.
Mike Jones (26-1, 19 KO) was expected to dance around the ring and just jab Bailey to net a unanimous decision victory.
But with a vacant IBF welterweight world title on the line and this likely being Bailey's last chance at a world title belt, a determined Bailey kept coming and was not going to be deterred.
Jones started occasionally subjecting himself to return fire by mixing it up with Bailey as the rounds went on. Then in Round 10, Bailey sent Jones to the canvas with a straight right out of nowhere.
Jones got up and recovered, but a right uppercut in Round 11 sealed his fate. Jones fell dramatically backwards in probably the most picturesque knockout of the year. Old man Bailey shocks the world.
Why was this an upset?
Bailey was 37 years old and his previous performance against Yoryi Estrella (10-7-2, 7 KO) last September was horrific. Bailey looked slow and undeserving of a title shot.
Jones was a fighter prone to mistakes, but redeemed by his speed and abilities. His promoter Top Rank also helped with good matchmaking.
Top Rank would only put Jones in with limited brawlers such as Jesus Soto Karass (26-7-3, 17 KO). These foes proved easy to outbox en route to another unanimous decision.
Bailey fit the description of yet another brawler, only a lot older and even slower. This was supposed to be an easy way to win a vacant title, but it was far from that.
Why this doesn't rank higher?
Bailey has the highest punching power of any foe Jones has faced thus far and Jones has shown that he can make mistakes in his previous efforts.
In his first match against Soto Karass, Jones gassed out early in the fight and allowed his opponent to outwork him. Jones won a controversial decision he cleared up with a rematch.
So it was no surprise to see Jones make another mistake in his fight with Bailey by mixing it up and not staying behind his jab.
Jones took a gamble he shouldn't have and Bailey's power is nothing to roll the dice with.
