LAS VEGAS (AP) _ Junior Jones settled his rematch with Marco Antonio Barrera the simple way Friday night, and with a lot less controversy.

Jones punched almost nonstop from the opening bell to score a unanimous 12-round decision over Barrera and retain the WBO junior featherweight title he won from Barrera in their first fight in November.

It was only the second loss for Barrera in 45 fights, and both have come at the hands of Jones.

But unlike the first fight, which ended in controversy after Jones hurt Barrera and the fight was stopped in the fifth round, Jones used a sheer volume of punches to win the rematch.

Statistics compiled at ringside showed Jones threw 1,005 punches to 556 for Barrera. He landed 316 to 280 for the former champion.

``There was no way I was going to let this go,'' Jones said. ``I worked too hard and wasn't going to let anyone take this away.''

Jones won 116-111 on one scorecard, 114-112 on a second and 114-113 on a third. The Associated Press had Jones winning 114-113.

Jones was aided by a point taken away from Barrera by referee Mills Lane for a low blow in the ninth round.

``I respect the judge's decision,'' said Barrera, of Mexico.

Barrera seemed ready to take control of the fight in the early rounds, but Jones came back and began pressing the attack in the eighth round.

Jones, 121, landed some big right hands in the 10th round, and the fighters stood toe-to-toe in the 11th round and traded head blows. There were no knockdowns in the fight.

``We both tried to impose our will but I was able to win that battle,'' said Jones, of Brooklyn, N.Y.

Jones (44-2) earned $250,000 while Barrera (43-2) was paid $125,000. Barrerra, 122, had been an 8-5 favorite.

In another title fight on the card, WBA welterweight champion Ike Quartey remained unbeaten by stopping Ralph Jones in the fifth round of a scheduled 12-round fight.

Quartey nearly stopped Jones in the first round of their WBA 147-pound title fight, knocking him down twice amid an almost unanswered barrage of punches.

Quartey finally ended the fight in the fifth round, hitting Jones with a vicious right hand that put him into the ropes. Referee Joe Cortez moved in and stopped the bout at 1:08 of the round as Jones was falling to the canvas.

``All I want to do right now is fight Oscar De La Hoya,'' Quartey said of the new WBC welterweight champion. ``That is where the money is and where my career is.''

Quartey, a 12-1 favorite, battered Jones nearly at will throughout the fight, throwing 497 punches and landing 278. Jones, by contrast, was credited with throwing 150 punches and landing only 38.

After four rounds, he was leading on all three ringside scorecards by six points.

``It was a very easy fight,'' said Quartey, of Ghana. ``He had taken enough of a beating.''

Quartey, 146 1/2, earned $500,000 for the sixth defense of his WBA welterweight title. His record improved to 34-0 with 29 knockouts.

Jones, 147, of Pittsburgh, fell to 30-2.
