The scores (100-90, 99-91 and 98-92) were lopsided in favor of Saucedo (30-1, 19 KOs), who used sustained pressure to pile up the points.

Fredrickson (21-3, 14 KOs), from Toledo, Ohio, dropped his second fight in a row.
“We worked on a lot of things in the gym. It was important for me to get the rounds in, and Sonny was a tough opponent,” Saucedo said.
“I am ready to take over the 140-pound division. Whatever opportunity comes my way, I will take advantage of it. Most importantly, I got rid of the ring rust and went 10 hard rounds.”
