- Hearns was ranked as the #3 welterweight by the WBC.
Muangsurin came out in the opening round with his gloves high and throwing very little. He often retreated to the ropes, where he covered up as Hearns threw, landed and punished his visibly slower opponent. By the end of the round, the Thai had already developed swelling to his left eye that would get worse as the bout continued. In Round 2, Hearns shot a straight right hand through the high and spread guard of Muangsurin that sent his straight down on his backside. He was up quickly and received the mandatory eight-count. Hearns followed up by pounding Muangsurin for the remainder of the round, landing both upstairs and to the body with heavy shots as the Thai simply was unable to defend himself. In Round 3, Muangsurin continued to take punches while looking to land a loaded left hand, his power punch. Another right hand, preceded by a jab this time, caught Muangsurin on the jaw and put him on his back. He was able to get to his feet at the count of seven and was allowed to continue. Despite being clearly outclassed, he was game and stayed in there as Hearns unleashed a brutal beating. Muangsurin was warned at the midway point of Round 3 for hitting on the break. A right hand in the final minute of the round wobbled Muangsurin. Hearns pressed the action and forced his opponent to the corner, where he landed repeatedly to the head, causing the referee to step in and wave an end to bout.
