In the middle of his big push, Onita finally won the NWA Junior Heavyweight Championship by
defeating Chavo Guerrero Sr. Onita received the belt and a trophy for his highly contested victory but when Chavo went to shake his hand, he shocked the fans by grabbing Onita and back suplexing him. Chavo Sr. proceeded to destroy the trophy by continuously hitting Onita and attacking him with it for a prolonged period of time, leaving him a bloody mess inside the ring. This angle even if done today would surely turn heads and get people talking.
Unfortunately, in the middle of this push by Baba, real tragedy struck after a match in 1983 against
Hector Guerrero. Onita slipped on some water outside of the ring and wound up tearing ligaments, cartilage and shattering his kneecap.
After surgery and recovery, Onita came back in late 1984 but it was obvious to Baba that Onita was much slower and wasn’t the same dynamic junior heavyweight that was for a short period of time chosen to be the ace to lead the division, so he had to let him go. Barely a month after his return, Onita was forced to retire in early 1985.
