LAS VEGAS – Yamaguchi Falcao’s movement and combination punching were too much for Morgan Fitch.

The southpaw from Brazil remained unbeaten by pounding out a 10-round unanimous decision over Fitch on the Yuriorkis Gamboa-Robinson Castellanos undercard at MGM Grand Garden Arena. Falcao won by the same score, 100-90, on all three scorecards.

The fight was the first of three televised by ESPN2 as part of the “Golden Boy Boxing on ESPN” series.

The 29-year-old Falcao, a bronze medalist at the 2012 Summer Olympics in London, improved to 13-0. The 34-year-old Fitch, of Pittsburgh, Pennsylvania, lost for the first time in his seven-year pro career (18-1-1, 8 KOs).

Falcao effectively used his straight left hand and stung Fitch several times with it, most notably during the sixth and eighth rounds.

Falcao connected with a straight left hand with about 2:15 to go in the eighth round. The punch made Fitch stumble backward, but he recovered quickly.

Falcao landed a combination just under two minutes remaining in the sixth round. Fitch took it well, but Falcao began gaining confidence against a taller opponent who had made the first half of their fight reasonably competitive.

Falcao also connected with a straight left that snapped back Fitch’s head toward the end of the sixth round.

Following Falcao’s victory, super lightweight prospect Vergil Ortiz Jr. knocked out Angel Sarinana in the third round of their scheduled four-rounder.

Dallas’ Ortiz hammered away at Mexico’s Sarinana with power shots for two-plus rounds before drilling Sarinana with a right uppercut that dropped him. Sarinana got up, but referee Jack Reiss determined that he shouldn’t continue.

The fight was stopped at 1:44 of the third round.

The 19-year-old Ortiz, who went past the first round for the first time as a pro, improved to 5-0 and recorded his fifth knockout. Sarinana slipped to 7-6-2 and was knocked out for the fourth time in his six-year pro career.
