If at first you don't succeed, try, try, try again. In his third attempt at a world title, Joseph "JoJo" Diaz Jr. (31-1, 15 KOs) of South El Monte, Calif. achieved his lifelong dream of becoming a world champion by defeating Philadelphia's Tevin Farmer (30-5-1, 6 KOs) via unanimous decision to capture the IBF Junior Lightweight World Title at the Meridian at Island Garden in Miami and streamed live on DAZN.

Diaz won with scores of 116-112, 115-113 and 115-113.

"In my previous opportunities, I needed to learn and deal with the adversity that I had been put through," Diaz said.

"I wanted to be an influence and a person who shows everybody that as long as you believe in yourself, you can overcome everything, any adversity. Despite everything, I was disciplined and focused, and I got the win this time. Tevin Farmer is a hell of a fighter. No matter what you say about him. He's been through everything. I respect him, and I thank him for giving me the opportunity."

For his part, Diaz's promoter Oscar De La Hoya of Golden Boy Promotions was over the moon.

"We are absolutely delighted that Joseph Diaz Jr. is now a world champion," said De La Hoya.

"Today is a very special day for us because Diaz Jr. is a young man who we signed about 8 years ago after participating in the 2012 Olympics, and now in his third opportunity he is a world champion. Golden Boy is getting stronger every day, and today's a perfect example of that."
