I think once you get into trying to play along in making sense of the mangled mess that are wba minor-major trinkets you set yourself up for a straight jacket. They see Vanes as #19 and honestly I don't think it should be counted after all 3 first refused to sanction and then granted special stipulations as last resort. IBF says he must fight Derevyanchenko and all it takes is a cut to screw him within 90 days. By the WBA this should be his 20th defense as on one hand they allow Vanes..who has never fought at middle..but disallowed Brook defense because he never fought at middle . It's the WBA well it's close enough rule.
