Tevin Farmer retained his IBF super featherweight belt by beating Jono Carroll via unanimous decision in Philadelphia.

American boxer Farmer defended his title on Friday after judges scored the fight 117-110, 117-111 and 117-111 against his Irish opponent at Liacouras Center.

Carroll tasted defeat for the first time in his career and he never stopped coming in the contest.

Farmer was pleased with his performance.

“It was a good performance, even when I am at my best, I will think I need to improve. He talked a lot but he showed up. That was a great fight,” Farmer said.

“You see, I boxed when I wanted to but I went inside when I wanted to. I wanted to go inside and see what he was hitting for, we had a lot of words. But he has a lot of heart and he showed it.”

Farmer improved to 29-4-1 with six knockouts as he called out WBA holder Gervonta Davis for a unification bout afterwards.

However, Farmer is not going to get short-changed on the deal. If Davis is slated to receive millions for the fight, then Farmer wants a big money offer as well.

Farmer's co-promoter, Eddie Hearn, had stated in several interviews that he was willing to give Davis $5 million to take the fight on the DAZN streaming service.

"Everybody knows what Gervonta Davis got offered. What is Tevin Farmer being offered?" Farmer said inside the ring.

"I feel like me and him, we built this fight up from 2014 to now. So, I think we should both get fair money, life-changing money. To answer your question, yes I do want Gervonta Davis ... if the business is right."

Elsewhere on Friday, Katie Taylor claimed the WBO lightweight championship with a ninth-round TKO against Rose Volante.

Maciej Sulecki was victorious by unanimous decision in his win over Gabe Rosado to take home the vacant WBO international middleweight belt.
