There was a point in the “fourth or fifth round” when Shawn Porter pulled back, then caught Errol Spence Jr. with a counter right hand.

Spence cursed in frustration, according to Porter, because he got hit with a punch Porter shouldn’t have been able to land. That’s when Porter suspects he “had” Spence in their welterweight title unification fight nearly seven months ago in Los Angeles.

Spence dropped Porter in the 11th round and won a split decision, yet Porter firmly feels he did enough to win that highly competitive contest September 28 at Staples Center.

“I thought I beat Spence,” Porter said during a recent Facebook Live interaction with fans. “When I heard split decision, I thought it was gonna be a split draw. I really did think that I beat him. I know I gave him a boxing lesson. And if a rematch is there for me, I would love to do it.”

Two judges – Rey Danesco (116-111) and Steve Weisfeld (116-111) – scored Spence the winner of eight rounds against Porter. Judge Larry Hazzard Jr. scored eight rounds for Porter, who won 115-112 on Hazzard’s card.

The 32-year-old Porter (30-3-1, 17 KOs), who lost his WBC welterweight title to Spence (26-0, ,21 KOs), completely disagrees with how Danesco and Weisfeld viewed their FOX Sports Pay-Per-View main event.

“The fight with myself and Errol Spence Jr.,” Porter said, “I think a lot of people thought that he was the guy who was gonna, you know, put me out. … I think, first of all, let me say that he’s another one of those great fighters. Just knows what to do, knows how to do it and can really get down in the ring. But I knew some things about myself that not many other people know. And I think one thing about me is I don’t shy away from a challenge. I actually love challenges.

“I thrive in challenges, and so, when that fight was made with myself and Errol Spence, I took it as, you know, the biggest challenge that could be. And, you know, for me, I look at the big things and the small things. You know, so where you may have saw I was a step or two ahead of him for a majority of the fight, those who don’t recognize that or don’t believe that or doubt that, you’re wrong. I was a step or two ahead of him the majority of the fight.”

CompuBox credited Spence, who retained his IBF title, for landing 49 more overall punches than Porter (221-of-745 to 172-of-744). According to CompuBox’s unofficial count, Spence connected with more power punches (184-of-416 to 142-of-553) and jabs (37-of-329 to 30-of-191).
