"Spinks did exactly what I thought he'd do. He was running from my left hand, which made him pull back and let me take it to his body."
The dethroned champion, son of former heavyweight champion Leon Spinks, called for a rematch after his third career loss in 37 contests.
"I want to fight him again," he said.
"This was a good fight. I gave him a chance and I hope he gives me one in return.
"I'm very disappointed because I let a lot of people down, but I have to hold my head up. I have to take this like a man."
Boxing in front of a hometown crowd of more than 20,000, Spinks had hoped to consolidate his grip on the division.
