SAN ANTONIO – Five-and-half-months after he narrowly won the WBC featherweight title, Mark Magsayo lost his 126-pound championship in similar fashion Saturday night.

Rey Vargas defeated Magsayo by split decision in their “Showtime Championship Boxing” main event at Alamodome. Judges Tim Cheatham (115-112) and David Sutherland (115-112) both scored their back-and-forth fight for the unbeaten Vargas, who lost 114-113 on the scorecard of judge Jesse Reyes.

Magsayo knocked Vargas to the canvas with a right hand in the ninth round, but he couldn’t finish the resilient two-division champion. The taller, rangier Vargas’ length and distance troubled Magsayo at times, but Vargas engaged more than Magsayo and others might’ve anticipated.

Mexico’s Vargas (36-0, 22 KOs) became a world champion in a second weight class and dealt the Philippines’ Magsayo his first defeat as a professional (26-1, 14 KOs).

“It wasn’t complicated at all,” Vargas said during his post-fight press conference. “But we really felt comfortable throughout. And technically, we felt sound. We knew that we were doing things right round-by-round. So, the end result was what we expected.”

The former WBC 122-pound champion, who was the mandatory challenger for Magsayo’s championship, took the title Magsayo won when he upset Gary Russell Jr. in their 12-round title fight January 22 at Borgata Event Center in Atlantic City, New Jersey.

The favored Russell (31-2, 18 KOs) entered their fight as boxing’s longest-reigning champion, but Magsayo beat him by majority decision (115-113, 115-113, 114-114) and ended a championship run that began in March 2015.

Against Vargas, Magsayo landed 64 fewer punches overall, according to CompuBox (196-of-687 to 132-of-451). CompuBox credited Vargas for landing more power punches (135-of-339 to 92-of-250) and jabs (61-of-348 to 40-of-201).

“No matter what, I’ll come back stronger,” said Magsayo, who is promoted by Manny Pacquiao’s company. “I’m disappointed, but I did my best.”

Based on how their fight was scored through 11 rounds, Magsayo needed a knockout in the 12th round to win.

A left hook by Magsayo made Vargas hold him with just over 1:30 left in the final round. Magsayo couldn’t land another damaging punch before their fight ended, however, because Vargas wisely kept his distance.

A right hand by Magsayo sent Vargas to his gloves and a knee with 41 seconds to go in the ninth round. Vargas tried to hold on to Magsayo as he fell, but Vargas went down anyway.

“It wasn’t a power punch,” Vargas said of the punch that dropped him. “It wasn’t something that’s super hard. It was more of a bad moment and it was something that counted. He did get me, but we were able to move on and come back strong.”

Magsayo rocked Vargas with a right hand that made him stumble with 1:08 remaining in the eighth round.
