In the main event of the Golden Boy Promotions-promoted event at StubHub Center, Thurman (23-0, 21 KOs), of Clearwater, Fla., dropped Diaz in the second round. Diaz (40-10-1, 29 KOs), of Coachella, Calif., rebounded with a strong showing in the third but got hit with a body shot that ended the fight. Diaz, upon the suggestion of his corner between rounds, did not come out for the fourth.
Said Thurman, “I felt the body shot (to Diaz). I felt he was going to go down. I wondered if I hadn’t landed it clean enough. He’s a tough guy. He showed up to fight. You saw what he was doing in the ring. His rib… he had eight more rounds to go so he did what he had to do.
