MIAMI — Former Olympian Charles Conwell ended his fight Friday, July 15 at Buffalo Run Casino against Rick Graham like he did in his previous four: a knockout.

Conwell worked Graham into the ropes in the second round with a series of punches. A shot to the head led referee Gerald Ritter to halt the fight at 2:33.

“I listened to my corner … started hitting him with more cleaner shots,” said Four State Franchise member Conwell, now 4-0 with all four wins via knockout.

The previous three outings had been stopped in the second, first and first rounds.

“I’m not mad about the stoppage,” said Conwell, who is from Cleveland, Ohio. “He complained I hit him in the head, I guess it really hurt him.”

He’s now got four fights under his belt since making his pro debut in Miami on April 21.

“I like having a lot of fights. It keeps me sharp and it keeps me active,” Conwell said. “We’re just going to keep on winning by knockouts, impress the fans and give them a good show. I am always trying to get better, always in the gym working to get better.”

Promoter Tony Holden likes what he’s seen so far from Conwell, who was the last member of the 2016 USA Olympic team to turn pro.

“Charles looked great,” Holden said. “He took it easy in the first round. We were trying to get him some rounds, but came on strong at the end. The guy we were fighting didn’t have the best record (Graham has won just four times with two draws in 23 pro fights), but he doesn’t get stopped. We thought we’d get a lot of rounds in.

“Charles is at a different level. Charles is a mega top prospect and will be a world champion.”

“They are moving me in the right direction, trying to get me quite a few fights,” Conwell said. “They want me to stay active and I really appreciate that.”

Conwell’s brother, Isaiah Steen, also of Cleveland, didn’t need long to get his seventh pro win.

He took out Travis Nero (0-2) at 1:32 of the first round.

All seven of Steen’s wins have come on stoppages.
