**KEITH THURMAN VS. BROCK JARVIS**
One of the best welterweights of this era, the former unified champion Keith “One Time” Thurman will look to begin a run at a 154-pound world title when he takes on the Australian knockout artist Brock Jarvis in the 10-round main event on March 12.
Clearwater, Florida’s Thurman (30-1, 22 KOs) earned his “One Time” moniker by talking the talk and delivering with highlight-reel KOs. He has assembled one of the most impressive resumes among the top welterweights of this generation, having defeated former champions Shawn Porter, Danny Garcia and Robert Guerrero. That showdown with Garcia saw him become a unified world champion in a rare unification bout between undefeated welterweight world champions. Thurman’s only blemish came in a 2019 Fight of the Year against boxing legend Manny Pacquiao, with Thurman ending up on the wrong side of a narrow split-decision. Most recently, Thurman bested former world champion and current highly ranked welterweight Mario Barrios by unanimous decision in February 2022. He was set to face another top Australian fighter in former champion Tim Tszyu in March 2024 before being forced to withdraw due to injury.
“Brock Jarvis is a sturdy guy – rough and tough, an inside fighter – but he’s been sheltered on his island, in his little bubble,” said Thurman in the lead up to this fight. “I’m coming to pop that bubble…To me, he looks like somebody who knows how to go for the win, but has he really been swimming out there with the sharks? It doesn’t look like it to me. That’s what I’m bringing to the table – something he’s never seen before.”
The 27-year-old Jarvis (22-1, 20 KOs) has risen up the rankings in his native Australia ever since turning pro in 2015 as a teenager. He’s shown tremendous power throughout his time in the pro ranks, with a 15-fight KO streak following his pro debut and a current run that’s seen him earn stoppages in each of his last five victories. His only defeat came in a 2022 showdown against fellow Australian and former 140-pound world champion Liam Paro. He bounced back from that loss with back-to-back victories, knocking out Marlon Paniamogan in March 2023 before most recently stopping Adrian Rodriguez in December 2024.
“I was super excited to get this opportunity and I’m really looking forward to this one,” said Jarvis. “To have a fight of this magnitude against Keith Thurman means everything to me. If he thinks he’s coming here for a tune-up fight, then he’s got the wrong mindset and I’m gonna expose that on fight night.”
**MICHAEL ZERAFA VS. BESIR AY**
In the 10-round co-main event, former world title challenger Michael Zerafa, a longtime contender out of Australia, steps back into the ring to challenge streaking German contender Besir Ay and hopes to put himself in a position to earn another world title opportunity.
Melbourne, Australia’s Zerafa (32-5, 20 KOs) won four straight to earn the title fight that he eventually lost to reigning WBA Middleweight World Champion Erislandy Lara last March. He bounced back from that defeat to earn a victory over Tommy Browne in August 2024. Zerafa had previously split a pair of matchups against former champion and Australian rival Jeff Horn in addition to a first-round knockout of longtime contender Anthony Mundine. The 32-year-old also competed stateside in 2015 when he dropped a contest to former middleweight champion Peter Quillin. The veteran has also challenged former champion Kell Brook and defeated previously unbeaten fighters Danilo Creati and Isaac Hardman.
A pro since 2016, Ay (19-1, 9 KOs) will fight out of his native Germany for the first time on March 12, as he looks to upset Zerafa in front of his Australian fans. Since a split-decision loss in his second pro fight, Ay has put together 18 consecutive victories and earned the German middleweight title with a unanimous decision over Dustin Ammann in June 2023. Originally from Hannover, Niedersachsen, Ay has continued to increase his level of competition with 2024 victories over the previously unbeaten Armend Hasani in June and Milos Beranek in October.
**MATEO TAPIA VS. SERGEI VOROBOV**
A longtime friend and sparring partner of Tim Tszyu, Mateo Tapia steps back into the ring after competing in a memorable 2024 clash against Endry Saavedra, and can further his claim as a 160-pound contender as he battles Russia’s Sergei Vorobev.
The 26-year-old Tapia (17-0-1, 10 KOs) showed tremendous mettle in his October 2024 showdown against Saavedra, recovering from two knockdowns to put Saavedra on the canvas on his way to a majority draw. Born in Tijuana, Mexico, Tapia spent much of his career fighting out of Australia, where he put in over 500 rounds of sparring against Tszyu. Now training out of St. Petersburg, Florida, Tapia made his U.S. debut in October 2023 with a stoppage victory over Eric Robles, and followed that up with a 10-round unanimous decision over Keiber Gonzalez in Australia in April 2024.
Originally from Shlisselburg, Russia and now fighting out of Sydney, Australia, Vorobev (20-2-2, 14 KOs) first burst onto the scene by scoring a major upset in just his seventh pro fight when he defeated then 34-0 contender Konstantin Ponomarev to win the Russian super welterweight title. The 30-year-old would go on to pick up victories over veteran contenders including Diego Chavez and Breidis Prescott, in addition to a narrow split-decision defeat to two-time title challenger Karen Chukhadzhian. Vorobev enters this fight after fighting to draws in each of his previous two fights.
**TONGA TONGOTONGO VS. KIRRA RUSTON**
Light heavyweights Tonga Tongotongo and Kirra Ruston will battle to see who can remain unbeaten.
Tongotongo (9-0, 9 KOs) of Wollongong, New South Wales, Australia by way of New Zealand has shown enormous power in his young professional career, knocking out everyone he’s faced. The 26-year-old has fought all but one of his pro bouts in Australia, leaving the country for his last bout in Fiji as he stopped Sebastian Singh in the seventh round.
Ruston (4-0, 4 KOs) has done the same thing as his March 12 opponent, stopping each of his professional opponents inside the distance. The Southport, Queensland, Australia native is also 26 years old. Ruston has managed to stop three of his four professional opponents in the first round, and he’ll undoubtedly try to make quick work of Tongotongo when they square off.
**SONNY KNIGHT VS. JORDAN MARTIN**
Opening the five-fight stream on the PBC YouTube Channel will be Sonny Knight and Jordan Martin facing each other in a super welterweight attraction.
Newcastle, New South Wales’ Knight (4-0, 3 KOs) will be looking to make it back-to-back stoppages when he faces Martin on March 12. After knocking out his first two professional opponents, Knight went the distance and got a split decision victory over Laban Stringer, before retiring Lovepreet in his latest outing.
Martin (6-1, 2 KOs) of Sydney, New South Wales hopes to expand his current win streak to five in a row against Knight.
