Thanongsak Simsri Edges Cristian Araneta by Split Decision to Claim IBF Title

The Ota-City General Gymnasium in Tokyo hosted a gripping clash for the vacant IBF light-flyweight title as Cristian Aniadas Araneta (25–2, 20 KOs), known as “The Bomb,” squared off against Thailand’s Thanongsak Simsri (38–1, 34 KOs). The meeting of two known punchers promised fireworks, and they delivered. Araneta, a 30-year-old southpaw from Cebu City, entered with a solid reputation. At the same time, 25-year-old Simsri, an orthodox operator from Si Sa Ket, Thailand, boasted a staggering 87 per cent knockout rate and a slick jab. The undercard energy surged as Tokyo’s MMA-meets-boxing crowd leaned forward, sensing something special brewing between two hungry, powerful light flyweights.

From the outset, Simsri used his jab to control distance and rhythm, landing crisp single punches while staying movable. Araneta answered with caution, probing cautious body shots, but Simsri’s jab combinations kept the Filipino off balance in rounds one and two. Early scorecards favoured the Thai, yet in round three, Araneta delivered a dramatic moment. A sharp, looping left counter connected on Simsri’s chin, dropping him flat in mid-round and costing the Thai valuable momentum. The southpaw power behind those counters showcased Araneta’s ferocity—despite being the challenger, he shifted the tide temporarily with a flash knockdown.

After that pivotal moment, the fight opened up. Both men tightened their games; Simsri reinforced his jab-first approach, adding timely combos, while Araneta hunted bombs in close. Body shots thudded, crosses cracked, and footwork became central. Simsri’s strategy was disciplined; he rarely turned and attacked only when clear openings appeared. Araneta, relentless and aggressive, pressed the tempo, digging with southpaw angles, his left hand primed. According to unofficial tallies, the tally was roughly even in punch volume, but Simsri showed slightly cleaner work through round ten, relying on boxing skill over brute force.

As the title rounds rolled on, the gymnasium’s atmosphere rippled with tension. Local Japanese fans, there for the main event, also embraced the world title undercard, feeling the suspense grappling in each round. Rounds 11 and 12 were gut checks: Simsri stayed composed, countering and jabbing with precision, while Araneta stalked, loaded his punches, and hunted openings. The third judge’s score sheet favoured Araneta, likely crediting his knockdown and forward drive. Still, two judges edged Simsri’s technical edge, awarding him 115–112 and 116–111 and crowning him world champion by a split decision.

Simsri’s record soared to 39–1 (34 KOs), adding the IBF light-flyweight title to his resume dating back to 2018. His perfect balance of jab and power, combined with his ability to take a knee and rebound, demonstrated maturity and ring intelligence. Araneta, though falling to 25–3, emerges with respect—his knockdown shone as a career highlight and evidence of his punch power and spirit when it mattered most.

Technically, the fight was a masterclass in small-weight warfare. Simsri utilized his jab to disrupt Araneta’s timing, kept the southpaw off balance with lateral movement, and mixed in combinations that pared through Araneta’s guard. Araneta’s southpaw stance and forward pressure created moments of explosive impact—his left hook in round three and subsequent power shots were textbook southpaw counters. Still, Simsri’s consistent control of clinches and pace denied Araneta many of the sustained bursts he needed. That clash between raw power and calculated control defined the contest.
