NEW YORK — Jahi Tucker overpowered D’Andre Smith to go undefeated on undercard Artur Beterbiev-Joe Smith Jr. on Saturday night.
Tucker beat Smith in most of the last three rounds of their welterweight bout at the Hulu Theater in Madison Square Garden. A New York State Athletic Commission doctor eventually directed referee Shawn Clark to stop the one-sided action at 2:27 a.m. of the fourth round.
Smith (11-2, 5 KOs) of Decatur, Georgia, never went down, but he received an excessive number of punches from 19-year-old Tucker (8-0, 5 KOs).
Tucker, of Deer Park, New York, first injured Smith in the second round when he unloaded countless unanswered power punches on the defenseless Smith.
In the previous fight, Floyd Diaz honored the memory of his grandfather by defeating Daniil Platonovschi on Saturday night.
Diaz, whose paternal grandfather died on Saturday afternoon, recorded a six-round unanimous victory over Platonovschi to remain undefeated. Judges Ron McNair and Robin Taylor scored all six rounds for Las Vegas’ Diaz (5-0, 1 KO) who, according to judge Eric Wolinski, won his junior featherweight bout 59-55.
Moldova’s Platonovschi lost for the first time as a professional (4:1, 2 KOs).
Diaz maintained control throughout the sixth round when it became apparent that Platonovschi needed a knockout to win.
Diaz connected with back-to-back right hands with just over a minute remaining in round five. A left hand from Platonovschi caught the attention of Diaz at 1:10 into the fifth round.
Diaz landed several straight right hands in the fourth round.
A straight left hand from Platonovschi assisted Diaz just halfway through the third round. An entanglement sent Diaz and Platonovschi to the canvas about 50 seconds into the third round.
A right hook from Platonovschi tipped Diaz off balance with about 30 seconds to go in the first lap.
In the fight before Diaz won, middleweight Troy Isley stopped Donte Stubbs in the sixth and final round of their fight.
Isley (6-0, 4 KOs) of Alexandria, Virginia dropped Stubbs twice, once apiece in the fourth and sixth rounds before referee Charlie Fitch stopped the action 38 seconds into the sixth round.
An overhand right from Isley sent Stubbs face first to the canvas just 29 seconds into the sixth round. Stubbs (6-6, 2 KOs, 1 NC) beat Fitch’s count but he was unable to continue.
Isley took Stubbs down first with a right hand that left him flat on his back with 10 seconds left in the fourth round.
Stubbs, of Riverside, Calif., has lost six straight fights but had not been knocked out until Saturday night.
