22-year-old former WBO super flyweight champion “Marvelous” Marvin Sonsona hails from General Santos City, in the Philippines and is committed to regaining his name as a top contender in the featherweight division.

The powerful southpaw Sonsona started boxing at 7 years of age under the tutelage of his uncle and fought 150 times as an amateur before turning professional.

He won his pro debut at flyweight on points then knocked out his next ten opponents in the early rounds.

All his first opponents were unknowns but then he also knocked out former two-time WBC world Champion Thai fighter Wandee Singwancha (record 57-10) via second-round KO.

Sonsona climbed up in weight to challenge José López for the WBO super flyweight title on September 5, 2009.

He scored a knockdown in the fourth round and fought his way to a unanimous decision victory.

On November 20, 2009, Sonsona vacated his newly won WBO super flyweight title after not being able to make the weight limit for his first title defense. The bout still went on with the WBO title at stake but only his challenger, Alejandro Hernandez (22-7-1), had the chance to win. At the end of the bout, the judges had it a split draw.

On February 27, 2010, Sonsona jumped two weight divisions, challenging then-undefeated Wilfredo Vázquez, Jr. for the vacant WBO super-bantamweight title, but lost by knockout in the fourth round.

Sonsona was scheduled to face WBO Latino featherweight champion Orlando Cruz last July 6 at the Hard Rock Hotel and Casino in Las Vegas but was forced to withdraw because of a “lumbar sprain and strain” according to Chiropractor Roger Anderson. Anderson said Sonsona was also suffering from a “left thigh strain” and was advised “not to run or lift weights for six weeks.”

He has recently been training with super trainer Pablo Sarmiento at his camp in Oxnard, California.
