Scores were 117-110, 117-110, and 115-112 for Pedraza, who was previously the IBF 130-pound champion of the world.
With the victory, Pedraza (25-1, 12 KOs) is expected to fight WBA lightweight champion Vasiliy Lomachenko on Dec. 1 to unify two of the division’s titles. Pedraza returned from a 14-month layoff in March and won two bouts to earn the shot at Beltran.
“We did everything that we needed to do to win this fight. We followed the game plan perfectly,” Pedraza said. “I knew how tough this fight was going to be and at moments it got very difficult, but thanks to the focus and the guidance from my corner, we were able to win round by round and get the win.”
Said Beltran, who fell to 35-8-1: “I thought it was a good, close fight. The knockdown made the difference. I got caught with a really good shot.”
