Manchester - Carl Frampton added Scott
Quigg's WBA super-bantamweight belt to his IBF one by winning their unification
fight by split decision on Saturday.
Frampton, from Northern Ireland, was only a slight favorite against local fighter Quigg, and the fight between the unbeaten pair also played out closely over 12 mainly cagey rounds before a sell-out crowd of 20,000.
A good final round by Frampton, who frustrated Quigg and came off the ropes with uppercuts, may have decided it for the judges, two of whom scored it 116-112 for Frampton. The third gave it to Quigg by 115-113.
Frampton improved his record to 22-0, having owned the IBF belt for a year.
Quigg's record dropped to 31-1-2, having lost the WBA version he's owned for three years.
