In the Floyd Mayweather v Andre Berto PPV co-feature, Roman Martinez and Orlando Salido engaged in a brutal battle through twelve rounds for the WBO super featherweight belt.
The pair participated in a rematch of their April meeting won by Martinez who clung to his title this time via a split decision draw.
Judges saw the contest 115-113 to either fighter, whilst a third had it 114-114 and Salido can count himself unlucky not to regain the title.
Badou Jack kept the WBC super middleweight title in his possession with a split and entertaining decision triumph over Britain’s George Groves.
The US-based Swede dropped Groves in the first round with a sweet shot to the temple which ultimately proved to be a telling moment in the fight.
Judges at ringside gave the champion the nod after twelve rounds that swayed one way then the other as two officials had it 116-111, 115-112 to Jack.
A third saw it 114-113 to Groves who has now lost his last three world title challenges following back-to-back defeats to Carl Froch.
In the pay-per-view opener, Jonathan Oquendo scored the best win of his career by carding a majority verdict over ex-world champion Jhonny Gonzalez. After a hard-fought ten rounds, the Puerto Rican came out on top 98-90 and 95-93, whilst the third judge saw it 94-94 even.
Vanes Martirosyan dropped Ishe Smith down twice to effectively end the former IBF super welterweight’s chance of regaining the belt in the immediate future with a majority decision victory.
Judges carded 97-91 twice and 95-95 to hand ex-world title challenger Martirosyan a 36th career win and a possible second shot of his own following a previous loss to Demetrius Andrade.
Earlier, there were knockout wins for Chris Pearson, Ronald Gavril, Gervonta Davis and Trakwon Pettis, whilst Ashley Theophane moved closer to a possible world title shot against the winner of Adrien Broner v Khabib Allakhverdiev for the vacant WBA belt at 140lbs with a ten round triumph over Steve Upsher.
