Former cruiserweight world champion Guillermo Jones recorded the 40th professional victory of his career in Panama to make a successful debut at the heavyweight limit.
The veteran, 43, moved up following a controversial reign at 200lbs which was dogged by a failed drugs test and subsequent suspension in the run-up to scheduled rematch with Denis Lebedev in 2014. Jones was eventually stripped of his belt and is now eyeing a shot at the top division belt after piling on 25 pounds.
Jones was eased into his new weight class by being matched up with Mexican also-ran Daniel Cota and won every round of ten at the Al Brown Arena to hopefully move on to sterner tests in the heavyweight ranks.
Elsewhere in Las Vegas, super middleweight force Gilberto Ramirez warmed up for a potential shot at the winner of Arthur Abraham v Martin Murray by carding a one-sided points win over Gevorg Khatchikian.
‘Zurdo’ has hardly lost a round in reaching 33-0 with 24 KO’s through his career and the 24 year-old had no problems using his superior skills to keep Khatchikian at bay for the duration of the contest.
Also on the bill at The Cosmopolitan, Konstantin Ponomarev, Saul Rodriguez, Casey Ramos, Toka Kahn Clary and Oleksandr Gvozdyk all remained undefeated.
In the UK, Jazza Dickens scored a split nod over Martin Ward to make the first defence of his British super bantamweight belt, whilst Conrad Cummings and Alfredo Meli shared the spoils over ten rounds in Belfast.
Cummings and Meli both kept hold of their unbeaten records, although a rematch could happen between the two in 2016. Marco McCullough and Patrick Hyland Jnr also enjoyed wins on the undercard at Waterfront Hall.
