Reito Tsutsumi had to dig through resistance, pressure, and his own mistakes before finally stopping Leobardo Quintana in the fourth.

From the opening bell, Quintana did what a seasoned pressure fighter is supposed to do. He closed the gap, worked the body, and made Tsutsumi fight at a pace he didn’t fully control. The early rounds weren’t pretty. Tsutsumi was getting touched, especially up top, and the blood around the nose told the story. Quintana wasn’t winning clean, but he was making the young southpaw uncomfortable, forcing exchanges instead of allowing him to box at range.

Tsutsumi’s response came through timing, not dominance. He stayed composed, kept his eyes up, and trusted his counters. The left hand was the key. He landed it clean more than once, both upstairs and to the body, and that gradually slowed Quintana’s pressure. By the third, the pace had shifted. Quintana’s feet weren’t as busy, his punches had lost snap, and his entries became predictable.

The finish came the way most pressure fighters get stopped: walking in without a plan. Tsutsumi placed a short right, followed by a clean left that sent Quintana down. He beat the count but his legs were gone. The referee had no choice but to step in.

This was a working man’s stoppage. Tsutsumi showed composure, decent punch selection, and the ability to adjust under pressure. He also showed some flaws. He backs up too straight. He accepts exchanges he doesn’t need to. Against a cleaner pressure fighter with better balance, that becomes a real problem.

Still, this was his first scheduled eight-rounder, and he handled the moment. That matters. What comes next should be about tightening the footwork and learning to control range, not rushing toward bigger names. Because if he doesn’t clean those things up, the next guy won’t need four rounds to find him.
