“It was very hard to survive,” Bika said. “I always work hard. When you are working hard, everything comes out right.”
Periban, who suffered a cut on the left side of his head after an accidental head butt in the eighth round, staggered Bika for a moment early in the 12th, but could not capitalize.
“It was definitely a strong fight. I showed my best against him, and I deserved to win,” Periban said. “I’m a better boxer, a cleaner boxer. He started the head butts. He even hit me in the neck one time.”
It was the first world title fight for Periban, but the fourth for Bika, who had lost unanimous decisions to unbeaten American Andre Ward and Welshman Joe Calzaghe and drawn with Germany’s Markus Beyer in the previous three.
The WBC stripped the title from Ward earlier this year, saying he had not fought a mandatory challenger soon enough nor shown proof to support his claim of a shoulder injury that had required surgery.
Bika called out Ward for a rematch after his victory.
“If Andre Ward wants to fight me, come to my manager. I’m ready,” Bika said. “I want to fight him. I want to fight the best.”
