The Main Event of UFC 172 between the No. 8 and 9 contenders in the Heavyweight division. 39-year old Alistair Overeem is nicknamed "The Demolition Man," but he's been anything but the last five bouts, losing three of them. He comes off a loss in December to Jairzinho Rozenstruik via a fifth-round knockout. He also lost back-to-back fights to Curtis Blaydes (third round) and Francis Ngannou (first-round knockout). Now he matches up with Walter Harris, three years younger, and a fighter on a roll. Harris is unbeaten in his last four bouts, with three of the wins coming by early stoppage. He's off two straight victories where he's earned a Performance of the Night bonus. His last two fights were impressive and over early, topping Sergey Spivak in 50 seconds and Aleksei Oleinik in 12 seconds. Every fight he's won has been via KO or TKO. Within the last year, both of these fighters beat Oleinik in the first round. Overeem won in 4 minutes, 45 seconds, while Harris won in 12 seconds. Take Walter Harris to win the bout.
