Miguel Cotto made his return to the boxing ring Saturday night after nearly two years without a fight, and he looked the part of a veteran champion as he decimated Yoshihiro Kamegai en route to a resounding unanimous-decision victory Saturday night at the StubHub Center in Carson, California.

Following his defeat at the hands of Floyd Mayweather Jr. on Saturday, Conor McGregor was grateful for the opportunity to share the ring with one of boxing’s biggest stars, but he would have liked a little more time to work.

Referee Robert Byrd stepped in to wave off their bout and award Mayweather the match by 10th-round TKO in the main event at the T-Mobile Arena in Las Vegas, Nev. McGregor was not knocked down at any point in the match, but the finish came after a series of unanswered blows from Mayweather that left the UFC lightweight champion on the ropes.

NEW YORK CITY -- There was no need for Floyd Mayweather Jr. (50-0, 27 KOs) to run away to seal another win.

As boxing's Albert Eisnstein, Mayweather's mass-energy equivalence was his potent jab-straight combo, enough to wreck ambitious mixed martial arts (MMA) boss Gregor McGregor (0-1, 0 KOs) via 10th round technical knockout (TKO) on August 27 at the T-Mobile Arena in Las Vegas.

In a truly ugly mismatch, former 4 division world champion Miguel Cotto (41-5, 33 KOs) beat Yoshihiro Kamegai (27-5-2, 24 KOs) by a terribly one-sided fight on Saturday night to win the World Boxing Organization 154lb tile in a fight televised by HBO at the StubHub Center in Carson, California.

The scores were 120-108, 118-110 and 119-109. Boxing News 24 scored the fight 120-108.

Floyd Mayweather Jr. beats Conor McGregor in round 10 Via Technical Knockout. Mayweather to take his record to 50-0.He passes Rocky Marciano for most wins without a loss/draw in boxing history. Mayweather backed McGregor onto the ropes with a series of rights and lefts. McGregor’s face was completely bloodied. He was about to fall through the ropes, and the referee stepped in to stop the fight with 1:55 remaining in the round.

Former super middleweight champion Badou Jack (22-1-2, 13 KOs) trounced WBA World light heavyweight champion Nathan Cleverly (30-4, 16 KOs) in stopping him in the 5th round on Saturday night on the undercard of the Floyd Mayweather Jr. vs. Conor McGregor card on Showtime pay-per-view from the T-Mobile Arena in Las Vegas, Nevada.

Jack, 33, battered Cleverly, bloodying his nose and hitting him at will until referee Tony Weeks stepped in to stop the slaughter at 2:47 of round 5. Cleverly was just covering up, taking shots and not letting his hands go nearly enough to keep Jack off him.

Mayweather says he won’t fight again. He’s 50-0.

Floyd Mayweather beat Conor McGregor in the 10th round of their fight on Saturday night in Las Vegas. Referee Robert Byrd stopped the fight as Mayweather pummeled a clearly fatigued McGregor. In an interview after the bout ended, Showtime’s Jim Gray asked Mayweather if he’d ever fight again, now that he’s 50-0 as a professional.

Sergiy Derevyanchenko (11-0, 9 KOs) stayed unbeaten with a 12th round knockout over #1 IBF Tureano Johnson (20-2, 14 KOs) in an IBF middleweight eliminator bout on Friday night at the Buffalo Run Casino in Miami, Oklahoma.

Derevyanchenko, 31, knocked Johnson down with a left hook to the head in round 12. The referee halted Gary Ritter then stopped the fight. The official time of the stoppage was at 0:40 of round 12. This was one of the most grueling televised fights of 2017. I can’t remember seeing anything nearly as hard a fight for both competitors as tonight’s Johnson vs. Derevyanchenko.
