Manny_Pacquiao : Flyweight division

Early years at Light Flyweight division

In 1995, the death of a young aspiring boxer and close friend Eugene Barutag spurred the young Pacquiao to pursue a professional boxing career. Pacquiao started his professional boxing career when he was just 16 years of age, stood at 4'11'', and weighed 98 pounds (7 pounds under the minimumweight division). He admitted before American media that he put weights in his pockets to make the 105 pound weight limit.His early light flyweight division fights took place in small local venues and were shown on Vintage Sports' Blow by Blow, an evening boxing show. His professional debut was a four round bout against Edmund "Enting" Ignacio, on January 22, 1995, which Pacquiao won via decision, becoming an instant star of the program.
Pacquiao's weight increased from 106 to 113 pounds before losing in his 12th bout against Rustico Torrecampo via a third round knockout. Pacquiao failed to make the required weight, so he was forced to use heavier gloves than Torrecampo, thereby putting him at a disadvantage.

Following the Torrecampo fight, Pacquiao continued undefeated for his next 15 fights. He went on another unbeaten run that saw him take on the vastly more experienced Chokchai Chockvivat in flyweight division. Pacquiao knocked out Chockvivat in the fifth round and took the Oriental and Pacific Boxing Federation (OPBF) Flyweight title. After one official defense and two non-title bouts, Pacquiao got his first opportunity to fight for a world title. Pacquiao captured the World Boxing Council (WBC) Flyweight World Title (his first major boxing world title as well as the flyweight lineal title) over Chatchai Sasakul by way of knockout in the eighth round. He defended the title successfully against Mexican Gabriel Mira via 4th round technical knockout. However, Pacquiao lost the title in his second defense against Medgoen Singsurat, also known as Medgoen 3K Battery, via a third round knockout. The bout was held in Nakhon Si Thammarat, Thailand. Singsurat got Pacquiao on the ropes and landed a flush straight right to the body coiling Pacquiao over and keeping him there. Technically, Pacquiao lost the belt at the scales, as he surpassed the weight limit of 112 pounds
