- Chang catches Kittikasem with a left hook that floors him moments into round 5. Kittikasem rises quickly from the knockdown and appears to have his legs under him.
- After rising and taking the count, Chang applies heavy pressure on the Thai fighter, catching him with another flush left hook shortly before the halfway point of the 5th round that sends the Thai fighter face first to the canvas scrambling to his feet. Kittikasem is noticeably more stunned than he was after the initial knock down. Chang applies heavy pressure for the remaining half of the round, landing several flush punches in combination but Kittikasem manages to survive until the bell.
- After a competitive first four rounds Chang scores two knock downs in round 5 that swing the momentum of the bout in his favor. Rounds 6 and 7 see a surging Chang pressuring his younger Thai opponent, connecting with several hard punches in each round and dictating the pace of the fight. To begin round 8 Kittikasem comes out flat footed, completely changing his tactics and begins exclusively throwing hard haymakers, many to Chang's body. A brutal fight breaks out with both fighters standing their ground throwing fight ending punches for almost the duration of the round. The prolonged body attack by Kittikasem seems to pay off, as he for the first time takes control of the fight with a suddenly weary looking Chang returning to his corner.
- Kittikasem knocked down and onto the seat of his trunks by a Chang straight right early in round 11. He rises at the count of two, seemingly not badly hurt.
- With a minute to go in the 12th round, Chang is caught with a flush left hook while deep in a crouch that badly hurts him. A flush straight right hand follow up catches him as he reels backwards with his hands down. Chang rises and beats the count, but his legs are completely gone and he is is knocked down again by the first Kittikasem punch. Tony Perez waves off the contest with Chang badly hurt and being partially supported by the ref.
