Gavilan fought in a very strong WW era (#2 to SRR) and moved up as WW Champ to lose by MD to Bobo Olson for the MW Title. IMO, Gavilan could have been a legit Jr. MW champ if the weight class had existed back in the mid-1950's Gavilan vs Olson. "Bobo Olson, last night, hacked and harassed a left handed punching Kid Gavilan, whose right eye was spurting blood from the 9th round on, for a majority 15 round decision before 18,562 roaring fans at the Chicago Stadium. Gavilan repeatedly flashed vicious left hooks to the body and head which seemed to stun Olson. But Bobo seldon took a backward step and was willing to match punching power whenever the Kid elected. Gavilan coasted through the 11th, 12th and 13th rounds, trying unsuccessfully to salvage each of those rounds with his patented flurries. In the final analysis, it was Bobo's persistency and crisp hacking combinations to the body and head which repulsed Gavilan's bid to emulate Ray Robinson's climb from the 147 to 160 pound championship."
