Minimumweight
Strawweight (also referred to as minimumweight or mini flyweight) is a weight class in combat sports.
Boxing
In professional boxing, boxers in the minimumweight division may weigh no more than 105 pounds (48 kg). This is a relatively new weight category for professionals, first inaugurated by the major boxing sanctioning bodies between 1987 and 1990.
Ricardo López holds the record for most consecutive title defenses at this division, with 21 defenses of the WBC title.
History
The minimumweight division was originally introduced in 1968 for the Summer Olympic Games under the name light flyweight. However the division was not recognized by any of the four most widely-regarded sanctioning bodies until the International Boxing Federation (IBF) in June 1987 when Kyung-Yun Lee knocked out Masaharu Kawakami to become the inaugural champion.
The division was then later recognized by the World Boxing Council (WBC) in October 1987, the World Boxing Association (WBA) in January 1988, and the World Boxing Organization (WBO) in August 1989, while Ring magazine did not begin ranking minimumweights until 1997 under the name strawweights and has yet to name a champion in their rankings.
