Are you talking about Fully Obel? He was just a contender, and one with a weak chin at that. I wouldn't think this would go more than a few rounds. Ayala would maul him. Fully was long and had some pop, but I couldn't see him being able to keep Tony off him.
Fulgencio Obelmejias could not keep off Ayala. Ayala would get to him in about the seventh round or so. Want to see a great knockout? Check out the Hagler-Obel fight. Hagler winds way back and delivers a Crunching Blow! OUCH!!!
