SAN ANTONIO – The more time Brian Castano took late Saturday night to think about what occurred in the ring at AT&T Center, the worse the WBO junior middleweight champion felt about the official result.

“It was a tough fight, of course,” Castano said during the post-fight press conference following his 12-round split draw with Jermell Charlo. “But I feel that they robbed me. That’s the way I feel.”

Only one judge, New Jersey’s Steve Weisfeld, felt the unbeaten Argentinean deserved a victory over Houston’s Charlo in their 154-pound title unification fight. Weisfeld scored seven of the 12 rounds for Castano, who won 114-113 on Weisfeld’s card because Weisfeld scored the one-sided 10th round 10-8 for Charlo.

Nevada’s Tim Cheatham scored their highly competitive, entertaining encounter a draw, 114-114. Puerto Rico’s Nelson Vazquez absurdly scored nine rounds for Charlo, 117-111, in a main event Showtime televised.

Even Charlo disagreed with Vazquez’s scorecard during the post-fight press conference.

“I’m not taking anything away from Charlo,” Castano said. “He’s a big puncher. He caught me with some good punches at times, but I survived and overall, I think I won the fight. And, of course, needless to say I want the rematch because he still has the three belts that I need and that I believe that should be mine.”

Buenos Aires’ Castano (17-0-2, 12 KOs) acknowledged that Charlo hurt him in the second, 10th and 11th rounds. The 31-year-old Castano believes he hurt Charlo during the third round as well.

“I did my job,” Castano said. “He did his job. We measured our strength. He hurt me in the second round. I hurt him in the third round. And then I think for the same judges that could’ve left the door open for a draw … I don’t agree with it. Like I said, I feel like I was robbed, and I demand and I would love to have the rematch, because there has to be only one super welterweight champion.”

CompuBox counted 22 more connections for Castano overall (173-of-586 to 151-of-533). According to CompuBox’s unofficial statistics, Castano landed more power punches (164-of-400 to 98-of-246) and Charlo’s jab was much more effective (53-of-287 to 9-of-186).

Charlo (34-1-1, 18 KOs), who retained his IBF, WBA and WBC titles, didn’t use the word robbery, but he also feels he deserved to leave the ring as just the sixth fully unified champion of the four-belt era.

“Honestly, I think that it was a closer fight than it seems,” Charlo said. “Somebody had it like 117-111. I do feel that I won a little bit more rounds than he did, [but] 117-111 was kind of a large range. But I do feel that there’s no way possible that you could just like, ‘Oh, 114-114.’ You know what I’m saying? Not to take anything away from what Brian Castano did, but I feel like I pushed a lot harder tonight than he did. You know, he wasn’t running in there, trying to be the Brian Castano he was. I took him out of his game plan.”
