1985-08-18 Lupe Pintor w pts 12 Juan Meza, Sports Palace, Mexico City, Mexico - WBC. Referee: Octavio Meyran. Scorecards: 115-111, 116-110, 117-110. Turning the clock back at the age of 30, Pintor (122) shrugged off two bad cuts to floor Meza (122) three times on his way to landing the title. Twice in the fifth Meza was dropped from long rights, and after doing well to come back he was again dumped by a vicious left hook in the tenth. However, Pintor was so tired at this stage that the champion somehow struggled through to the final bell.
Pintor forfeited the WBC version of the title when he came in three pounds over the weight for a defence against Samart Payakaroon at the Hua Mark Indoor Stadium, Bangkok, Thailand on 18 January 1986. The fight went ahead on the basis that if Payakaroon won he would be proclaimed champion. Never threatening at any stage of the fight, Pintor was cut over the left eye in the fourth before being set up in the fifth by a right and sent crashing by a big left hook to be counted out on the 1.31 mark.
