Career
He is a native of Montebello, California. Frias began his professional boxing career on February 7, 1975, one month and a half after he had turned eighteen years old. He beat Alfredo Medrano by a six round decision in San Diego that night.
He made his Los Angeles debut defeating Victor de Louisiana Cruz on March 17 of that year.
Murray was undefeated before losing to Frias. Frias" first knockout victory came on his tenth fight, when he defeated Canelo Salinas in the second round on December 16 of that year.
An unclarified incident happened weeks before the fight, when some armed men came looking for Mancini at his hotel room as he trained for his challenge of Frias in the city of Tucson, Arizona. Frias himself was never signaled as a suspect in the incident, and Mancini-Frias took place on May 8, 1982 in Las Vegas.
On July 18 of that year, Frias bid for the USBA Lightweight title, losing by a fifth round knockout to Ruben Muñoz Junior., in Atlantic City, New Jersey.
He lost by a ninth round knockout to Lampkins. His next fight was also highly anticipated, as he faced former two division world title challenger and fellow Chicano Bobby Chacon, on August 15, 1985, in Sacramento. Despite dropping Chacon in the first round, Frias lost by a seventh round knockout.
Arturo Frias retired after that bout, with a record of 28 wins and 5 losses in 33 bouts, with 8 wins by knockout.
He currently resides in Whittier, California.
