For the second time in his career, Shawn Porter is a champion.

Porter won all three scorecards Saturday night inside the Barclays Center in Brooklyn vs. Danny Garcia to claim the vacant WBC 147-pound title.

One judge had it 116-112 in favor of Porter, with the other two giving it to him on scores of 115-113.

With the win, Porter (29-2-1) is now likely to face Keith Thurman to unify the belts once Thurman is healthy.

“I made a prediction and a hard one to live up to,” Porter said. “I said I wasn’t leaving New York without this belt and I’m not leaving New York without this belt.

“I knew he was going to be accurate. The game plan for me was to be accurate from the outside and show I could beat him without roughing him up on the ropes.”

In a matchup of accuracy vs. activity, Porter looked to outworked Garcia. He was relentless in his attack and threw 742 total punches and 544 power punches, landing 25 percent. Garcia, on the other hand, was the more precise fighter, landing the higher percentage and more meaningful punches. He connected on 46 percent of the 304 power punches he threw. Due to the contrasting styles, the three judges were only able to all agree on four rounds.

Garcia fell to 34-2 with the loss in front of over 13,000 fans.

“He was throwing a lot,” said Garcia, who falls to 7-2 in world title fights. “I had my defense tight, so I wasn’t feeling his punches. I thought I landed the clearer shots and won this fight.

“I have to sit back, relax and see what’s next for me.”

Errol Spence Jr., the reigning IBF welterweight champion, entered the ring afterwards and challenged Porter.

“The same way that you called Danny out, I’m going to call you out,” Spence said. “I think I’m the best welterweight in the division. I’m ‘The Truth’ and I guarantee you I come home as unified champion. I definitely want that fight against Porter.”

In the co-main event, Yordenis Ugas won a title-eliminator in the WBC welterweight division with a victory over Cesar Barrionuevo via decision.

Ugas, who is now 23-3-, has won eight fights in a row and snapped a 10-fight win streak for Barrionuevo (34-4-2). Adam Kownacki opened the main card with a decision victory over former IBF heavyweight contender Charles Martin for his 18th win in 18 pro fights.

Also, here’s a complete replay of the early bouts that streamed online prior to the start of the Showtime broadcast. The featured fight saw Amanda Serrano become a six-division champion with a victory over Yamila Esther Reynoso for the vacant WBO super lightweight title.

“This means everything to me,” Serrano said. “I work so hard and I hope this fight shows the fans that girls can fight and we can give it our all just like the men do. We deserve to have this platform and we deserve to be shown.”

Serrano joined Oscar De La Hoya and Manny Pacquiao as the only fighters to win titles in six different weight classes.
