Jerwin Ancajas set up a possible unification fight with Kal Yafai after his comprehensive points win against Jonas Sultan.
Jerwin Ancajas retained his IBF super-flyweight world title with a unanimous points win over Jonas Sultan, in California.
The Filipino was in control from start to finish, out-classing his dogged compatriot with the 110-109, 110-119, 117-111 scoring underlying his superiority.
Ancajas proved his technical skill but with WBA champion Kal Yafai making his American debut at the Save Mart Arena, in Fresno, he was ultimately overshadowed by the British star.
The IBF holder refused to rule out a unification showdown with Yafai after he made it five defences in just 16 months.
Highlights of Kal Yafai’s impressive American debut against Mexican David Carmona.
Sultan did his best to bring back memories of the Philippines’ legend, Manny Pacquiao’s wars, but despite a decent third round, he was always second best to the country’s only current world champion.
Ancajas controlled the pace, happy to lead from the front or sit back and pick his opponent off, whenever he pushed forward.
The combinations were crisp and well-placed but with the Californian clearly unimpressed by the lack of knockout action, it was always likely to go the distance.
Ancajas tried to get the job done early down the stretch but Sultan was fit and fierce throughout, his face reddened after 12 tough and technical 12 rounds.
