In a must-win fight for both middleweights, Gabriel Rosado stopped Glen Tapia in the sixth round of their Golden Boy Boxing on ESPN main event on Thursday night in Las Vegas.

Rosado (24-11, 14 KO) dropped Tapia (23-5, 15 KO) in the sixth round, then finished him off with another flurry of shots. The end came at 1:15 of the round.

Rosado, 31, called out top middleweights after the fight.

“Tapia’s the type of guy that when you hurt him, he’ll come forward,” said Rosado. “It was very important to get the win. It was important to make a statement, to be impressive, to put myself back into the mix. I want Canelo Alvarez, Danny Jacobs, or a rematch with David Lemieux. I want to prove that I still have something.”

In the co-feature, welterweight KeAndre Gibson improved to 18-1-1 (7 KO) with a 10-round majority decision win over Alejandro Barrera (27-4, 17 KO). Scores were 97-93 and 98-92 for Gibson, with the third judge scoring the fight 95-95.

“I feel good, you know. I feel great,” said Gibson. “I beat an experienced guy, though I think that I could’ve done a better. I’m going to box a little more next time. I’m going to control my distance more and relax. It was a good fight.”

“I feel sad because of the defeat,” said Barrera. “I should’ve done more defensive movements, so I’ll work on that for next time.”

Super featherweight prospect Bekman Soilybayev remained unbeaten, going to 12-0 (4 KO) with a 10-round unanimous decision win over veteran Fernando Vargas (32-15-3, 24 KO). Scores were 98-92, 99-91, and 100-90.

“I felt good. I went the distance, and I didn’t get tired,” said Soilybayev. “It was just like we practiced. I did all the things I’d been training for. But I do need to keep working at it and work harder to be a world champion. Moving forward, I’m going to work a little harder and polish my skills. I’ll do whatever my trainer says and work hard.
