At the age of 26, Jerwin is a nine-year pro. The IBF junior bantamweight world champion, he won the title in September, 2016, and has made five successful title defenses.
Jerwin is considered by most observers to be one of the Philippines’ top young talents, with the potential to become his homeland’s next major star. He was voted the “2017 Athlete of the Year” by the Philippine Sportswriters Association.
He is co-promoted by Filipino legend Manny Pacquiao’s MP Promotions – he’s Manny’s first world champion – and Top Rank, who calls him “the next Manny Pacquiao.”
Jerwin is undefeated in 17 fights – 16-0, 1 NSF, with 14 knockouts – since his only loss by 10-round majority decision in March, 2012.
He has fought 23 times in his native Philippines, five times in China, two times in the United States, and one time each in Australia, and Northern Ireland.
In his last fight on May 26, 2018, in Fresno, California, he won a 12-round unanimous decision against Jonas Sultan. It was the first world title fight between two Filipino fighters in 93 years, since flyweight world champion Pancho Villa defended the title with a 15-round unanimous decision win against Clever Sencio in Manila on May 2, 1925.
ESPN.com’s Ryan Songalia reported [excerpts]: It was a one-sided exhibition of Jerwin Ancajas’ technically flawless skills.
The southpaw from Panabo City, Philippines, retained his IBF junior bantamweight title for the fifth time, outboxing mandatory challenger Jonas Sultan to a unanimous decision victory. The scores were 119-109 on two cards and 117-111 on a third.
Ancajas controlled the fight from the opening round with his piston-like jab, closing off all entry points for Sultan to get on the inside and do work. Ancajas followed his jab with straight lefts to the midsection and the head and landed sneaky counter-right hooks whenever Sultan lunged forward without his jab.
Sultan had been stunned momentarily in the ninth round but wasn’t ever close to being stopped in the fight.
Ancajas never wavered from his game plan of boxing and counterpunching. Sultan had some success peppered throughout the whitewash, landing left hooks over the right hand of Ancajas from time to time but never could get anything of note going. [End Songalia item]
In his post-fight interview, Jerwin said, “It was a good experience to fight against Jonas. He hits hard, has a true heart of a Filipino. As I’ve said before, it’s really tough to fight versus Filipinos because they continue to keep fighting.”
Jerwin made his U.S. debut in his previous fight on February 3, 2018, in Corpus Christi, Texas, and won by 10th-round TKO against Israel Gonzalez.
