1978-05-06 Netrnoi Sorvorasingh w pts 15 Freddie Castillo, Thai Army Camp, Bangkok, Thailand - WBC. Referee: Rudy Jordan. Scorecards: 145-142, 150-141, 147-146. The fast-rising Sorvorasingh (107¼) split the right eyebrow of Castillo (108) as early as the second round and although the injury bothered the champion he managed to fight on even terms for quite long periods. However, in the end it was the Thai’s extra strength and aggression that won him the title.
