CARSON, Calif. - Showtime's tripleheader telecast opened with former two-division world champion Devon Alexander (26-2, 14 KOs), of St. Louis, winning a hard-fought unanimous 10-round decision in a terrific, fast-paced scrap over determined Jesus Soto Karass (28-10-3, 18 KOs), of Los Mochis, Sinaloa, Mexico

The southpaw Alexander, in his first fight since losing to Shawn Porter in December, was satisfied afterward.

“Soto Karass keeps coming, he's a tough competitor. I wanted to pace myself and see my punches more, instead of going out there and missing shots.

"I’m a good fighter with skills and I will be the best one day, I promise you.”

Offered Soto Karass: “I was trying to focus on the body, that was the plan, but I hurt my hand in the fifth round. Alexander was very fast. He was hard to hit and he has good skills. I was surprised he decided to hang in there with me and exchange.’’
