“Showtime” Shawn Porter made the first defense of his WBC welterweight world title over Yordenis Ugas in a primetime bout on FOX, taking place at the Dignity Health Sports Park (formally the StubHub Center).

The bout was close as the result of split decision showed. Porter for the second fight in the row, showed more a boxing centric approach than fights prior, and had Ugas hesistating early and often. Porter was cut by a punch from Ugas in the tenth round. It felt as though Ugas played around later in the fight too much, which let the fight slip away.

The judges had it 116-112 Porter, 115-113 Porter and 117-111 Ugas, for the winner Shawn Porter.

The co-main event saw welterweight tough guy, Abel Ramos get the biggest win of his career against Francisco “Chia” Santana. Ramos was dropped in round two, but a solid group of punches from Santana, but went back to fighting off his back foot and edged out Santana, who failed to cut off the ring.

Scores 98-92, 95-94 and 97-92 for Abel Ramos.

In the television opener, Ronnie Shields’ heavyweight Efe Ajagba ran through former world title contender Amir Mansour as he dropped Mansour twice in the first round, and hurt him bad in the second round. Mansour’s corner refused to allow him to answer the third bell giving Ajagba a second-round technical knockout win.

On the FS1 prelims, former bantamweight world champion Juan Carlos Payano proved his still game picking up a one-sided decision over undefeated prospect Damian Vasquez. A cut was opened up early in the fight on Payano from a headbutt. Payano appeared to have the bigger punch and was just too experienced for Vasquez, who was outgunned.

Scores 71-80, 71-80 and 79-73 for Payano.

Super welterweight Eimantas Stanionis went eight-rounds in his eighth professional fight winning every round against Samuel Figueroa, but getting hit a bit too clean for comfort as well.
