Former light heavyweight champion Roy Jones Jr resurrected his fading career by outpointing Prince Badi Ajamu in his comeback fight in Boise, Idaho.
The 37-year-old American improved his record to 50-4 with three scores of 119-106 as he eased to a fine win.
The victory gave Jones, who claimed five world titles at four different weights, the fringe NABO title.
It also ended a run of three defeats since 2003 to Antonio Tarver (twice) and Jamaica's Glencoffe Johnson.

Jones, once the world's best pound-for-pound fighter, revealed he had been training for nine months to fight 34-year-old Ajamu, who is ranked number six by the WBC and is a cousin of the late Floyd Patterson.
And afterwards Jones said he is now eyeing a crack at Britain's IBF/WBO super middleweight champion Joe Calzaghe, or even former middleweight king Bernard Hopkins.
"The champ is back," Jones roared afterwards. "But I only give myself a 'C' for that performance."
On the undercard, former IBF light heavyweight champion William Guthrie stopped Luke Munsen to win the vacant IBF international cruiserweight belt.
