Heavyweights collided in the Season 5 quarterfinals Oct. 1 at Bellator 52 in Lake Charles, Louisiana. Eight entered the tournament, but only four remain. In a razor close fight, Mike Hayes scored an upset over previous tournament runner-up Neil Grove and walked away with a split decision win. Grappling specialist Blagoi Ivanov showed drastic improvement in his hands before using a beautiful guillotine choke to put TUF-veteran Zak Jensen to sleep for a second-round submission victory. In a dynamic heavyweight fight, Eric Prindle survived an early blitz from Abe Wagner and hung on to win an exciting three-round decision. Opening the tournament was Ron Sparks, who lived up to his nickname “The Monster” and knocked out Mark Holata less than a minute and a half into the fight.
