Chantelle Cameron, already the WBC and IBF super lightweight titlist, added the vacant WBA, IBO and WBO belts to become the new undisputed champion on the Bivol-Ramirez undercard in Abu Dhabi.

Cameron's textbook long-range boxing, straighter punches and better timing combined with Jessica McCaskill's curiously flat performance in the first four rounds (Cameron led 54-32 overall and 36-27 power) allowed the Briton to build the mathematical cushion she needed to stave off a stronger performance by McCaskill in the later rounds (McCaskill led 59-52 overall and 42-32 power in rounds 7-10).

McCaskill, still the undisputed welterweight champion, lost for the first time since dropping a unanimous decision against Katie Taylor in December 2017. She was more active (62 punches per two-minute round to Cameron's 53.4) but Cameron's sharper jabbing (23.6 attempts/4.6 connects per round to McCaskill's 28.2/2.8) and better accuracy (25%-18% overall, 19%-10% jabs, 30%-25% power) resulted in final leads of 134-111 overall, 46-28 jabs, 35-33 body and 88-83 power as well as a 7-1-2 lead in the CompuBox round-by-round breakdown of total connects. Scoring: 97-93, 96-94 (2x).
