A Calculated Start Turns into a Tough Test
Quintana refused to give ground in the opening rounds and made Tsutsumi work for clean entries. The Japanese southpaw used feints and adjustments at close range, but Quintana’s counters and uppercuts kept the exchanges competitive. Tsutsumi’s nose was bloodied in the second round.
The pace and punch output made for a demanding early test. CompuBox counted 276 power punches thrown between them in fewer than four completed rounds, with Tsutsumi more accurate to the head and body, according to The Ring’s report.
Round 4: Tsutsumi Finds the Finish
About 45 seconds into Round 4, Tsutsumi landed a right hook that started the finishing sequence. He landed another right hook moments later, then followed with a three-punch combination. Quintana rose after the referee’s count, but the official stopped the fight at 1:14 of the round.
The win moved Tsutsumi to 4-0 with three knockouts and capped his 2025 campaign with a successful Riyadh debut.
A Prospect No Longer — Tsutsumi Is a Threat
The stoppage came after Tsutsumi had to adjust to an opponent who countered his entries and made the fight physical. He showed that he could keep solving problems under pressure, though the exchanges also offered a reminder that he was still developing at the professional level.
At the time, Tsutsumi was a junior lightweight prospect with a strong amateur background. The Ring noted that he was seeking a place in the world rankings in 2026, while also pointing to the shots he absorbed as an area to improve against harder-hitting opposition.
Quintana Shows Heart but Gets Overwhelmed
Quintana made Tsutsumi earn the stoppage and answered the fourth-round knockdown by getting back to his feet. The Mexican’s willingness to counter and exchange helped make the opening rounds competitive, but Tsutsumi’s late combination ended the contest before the scheduled eight rounds.
Final Word
Tsutsumi’s fourth-round stoppage of Quintana was a clear win, but not a one-way performance: Quintana’s counters tested him before the decisive combination. Tsutsumi has since added another knockout and improved to 5-0, giving the Riyadh bout useful context as an early test on his way up the divisions.
