Brock Jarvis, one of Australia's most promising boxing talents, is the new IBF intercontinental lightweight champion after surviving the sternest test of his career to keep his undefeated record intact.
Jarvis overcame a second-round scare to score a technical knockout over Mexican Alejandro Frias Rodriguez in a triumphant overseas debut in California.
At 23, the Sydney pugilist made his American professional debut four years younger than his famous trainer, triple world champion Jeff Fenech, did in 1991.
Jarvis was made to work for the victory, with Frias unleashing a flurry of combinations in round two that rocked the Australian, who survived only by the ropes keeping him up.
Jarvis was able to recover, find his feet and composure through rounds three and four, before taking the fight back to Rodriguez with unwavering pressure and limiting his space in the ring.
Pressing his head into the chest and shoulders of his opponent, made famous by Fenech, Jarvis landed heavy body shots and uppercuts before the referee stopped the fight midway through the fifth round.
The nephew of former NSW State of Origin hardman Pat Jarvis, the 23-year-old improves his record to 20-0, with 17 wins via knockout.
Jarvis said he was prepared to fight through any adversity.
"I hung in there and kept working to get the win," he said after making the successul step up from super-featherweight.
"I've come here to win and win at all costs, so a bit of adversity is not going to stop me."
Jarvis recently signed a long-term deal with Eddie Hearn's Matchroom Sport and said he was glad to get the win with the Englishman in attendance.
Fighting as the ninth-ranked 130-pound boxer by the IBF, Jarvis landed 42 per cent of his 304 punches thrown to his opponent's 44 per cent in Fresno.
