Belfast, Northern Ireland (SportsNetwork.com) - Carl Frampton stopped challenger Chris Avalos in the fifth round to retain his IBF Super Bantamweight title in his hometown.

Frampton hit Avalos with a flurry of combinations to prompt referee Howard John Foster to halt the scheduled 12-round bout at 1:33 of the fifth.

The title defense was the first for Frampton (20-0, 14 KO) of the belt he won from Kiko Martinez with a unanimous decision in September.

Avalos (25-3) entered the fight with six straight victories, the last three by knockout, and was the IBF's top-ranked contender.
