LAS VEGAS – Conor McGregor thought he was only down one round against Floyd Mayweather Jr. entering the 10th and ultimately final round.

The UFC superstar said during the post-fight press conference Saturday night that he felt Mayweather won five of the first nine rounds and that he won four of those rounds. The judges clearly didn’t agree.

Only one judge, Dave Moretti, gave McGregor more than one round out of the nine that were completed prior to Mayweather stopping McGregor in the 10th round of their scheduled 12-round, 154-pound boxing match at T-Mobile Arena.

Moretti gave McGregor (0-1) each of the first three rounds. His had Mayweather (50-0, 27 KOs) ahead 87-83 entering the 10th round.

Judges Guido Cavalleri (89-81) and Burt Clements (89-82) had Mayweather in front by even bigger margins than Moretti. Cavalleri and Clements gave McGregor only the first round on their cards, but both thought Mayweather won each of the following eight rounds.

“I think that’s very, very biased,” McGregor said during the post-fight press conference. “I’m actually shocked at that. I thought I won the first three rounds clearly. The fourth round could be argued either way. Say 3-1, and then he started to take over then. And I thought I snuck in eight, round eight. Then he won nine and got the stoppage in 10.

“So what was that, 5-4, into the final round? And then he got the win. But in reality, all that means nothing. He got the win. Respect to him. I enjoyed it. I thought I done OK. I thought I switch-hit it a few times. He was wise to that. I know Paulie [Malignaggi] was on the phone to him, telling him certain movements. But I switched, threw the lead hook and he pulled from it a few times beautifully. Then I switched and hit the lead to the body. I caught him once or twice with that. But he’s a smooth operator.”

According to unofficial CompuBox statistics, Mayweather landed 170-of-320 overall punches, 59 more than McGregor (111-of-430).

Mayweather was especially accurate with his power punches (152-of-261; 58 percent). The undefeated five-division champion landed only 18-of-59 jabs.

CompuBox credited McGregor with landing 84-of-332 power shots (25 percent) and 27-of-98 jabs (28 percent).
