Gomez is best known for being a competitor on the debut season of reality TV show The Contender, where he finished third out of sixteen fighters and instantly became a fan favorite.
Gómez holds notable victories over former world champions Arturo Gatti, Jose Luis Castillo, and Peter Manfredo Jr.
He has also fought household names such as Saul Álvarez, Miguel Cotto in a WBO world championship fight, and Shawn Porter.
Gómez was born in Guadalajara, Jalisco, Mexico, but his parents subsequently moved to the city of Oakland, California, where his boxing career began as a self-defense class due to constant bullying.
He has two brothers, Jesus Zeuz and Roberto Robb, who are part of a local Spanish hip hop group called Hy3rid H3.
Coming off a strong amateur career where he represented Mexico in the quarterfinals of the 2000 Olympic Qualifying Tournament for the Americas,[1] Alfonso Gomez turned pro in 2001, and was used by his first few managers as a stepping stone fighter for hotter-looking prospects.
In the quarterfinals, he beat the confident Ahmed Kaddour (who had been brought back in to replace Juan de la Rosa and as a thinly-veiled attempt by Manfredo, Brinkley, Gilbert, and Bonsante to psych out Ishe Smith) by unanimous decision in a tough matchup that Manfredo was allowed to make as the challenge winner of the week at the time.
He may take some consolation from having beaten Brinkley in the 3rd Place Fight, which guaranteed him a nice packet of prize money(200k and a 2005 Toyota Tundra)—and the whole Contender experience catapulted him to a world ranking of 21 out of 861.
Going back to his original weight class range of Welterweight/Light Middleweight, Gomez fought Luciano Perez in a five-round contest on October 15, 2005, at the Staples Center in Los Angeles on the Contender Rematch card, and won by fourth round TKO.
Gómez fought Jesse Feliciano for a third time to a draw after a long layoff on May 5, 2006, at the Aladdin Resort in Las Vegas, Nevada, on the Latin Fury card with the Contender Season 1 champion Sergio Mora.
On August 25, 2006, Gómez fought Carson "Kid" Jones in an eight-round bout at the Arco Arena in Sacramento, CA.
Gómez was a part of the American team on The Contender Challenge: UK vs. USA, where he was pitted against the hard-punching Martin Concepcion on March 30, 2007.
Alfonso won due to TKO from an uppercut followed by a left hook late in the 7th round after having largely dominated the fight prior to that.
Arturo Gatti needed a decent comeback opponent to determine whether he still had anything in the tank after a tough stoppage loss to Carlos Baldomir a year earlier.
Instead, Alfonso got a shot against then WBA Welterweight champion Miguel Cotto, who needed a stay-busy opponent to hype up a possible Antonio Margarito-Cotto match, with Margarito fighting Kermit Cintrón on the same card.
On November 14, 2009, Gómez fought against the favored Jesús Soto-Karass on the Manny Pacquiao vs. Miguel Cotto undercard "Firepower" at the MGM Grand.
Gómez fought José Luis Castillo on the Manny Pacquiao vs. Joshua Clottey undercard on March 13, 2010, at the Cowboys Stadium in Texas.
However, during training for the bout Alfonso tore some ligaments in his left elbow and had to withdraw from the card, and will undergo a few months of rehab.
Gómez fought and beat Calvin Green via 2nd Round TKO on May 21 at the Morongo Casino in California on a Fox Deportes card for his comeback fight off the injury to his left elbow.
Gómez went after and cornered Green, threw some more combinations and got another big right hand counter in that forced a stoppage by the referee.
On July 28, 2012, Alfonso Gómez faced off with undefeated Welterweight prospect Shawn Porter as the opener for the Guerrero vs Aydin card in San Jose CA.
After a near two-year layoff due to injuries and somewhat unlucky circumstances regarding a prospective Victor Ortiz fight, Gomez returned to the ring to face Ed "The Lion" Paredes in a ten-round junior middleweight fight on July 9, 2014, in Las Vegas as the main event of a Fox Sports 1 card.
On March 20, 2015, Alfonso Gómez fought Yoshihiro Kamegai as part of a Fox Sports 1 card at the Fantasy Spring Casino in Indio, California.
At the end of the bout, the unanimous decision by a wide margin was awarded to Gomez, his second win after his recent comeback.
