In the following fight, 17-year-old Tristan Kalkreuth made an impressive pro debut by stopping Kynndale Prather in the first round of a scheduled four-rounder.

Kalkreuth, a light heavyweight from Duncanville, Texas, wobbled Prather (0-2) with a left hook early in the first round. Prather retreated, but Kalkreuth caught up to him quickly, landed another left hook and followed it with a right hand.

Those shots knocked Prather into the ropes, but he remained on his feet.

Referee Rosario Solis quickly stepped in to prevent Prather from taking more punishment. Their fight was stopped 42 seconds into it.

Later Saturday night, junior welterweight contender Marcelino Lopez scored three knockdowns and stopped Daniel Echeverria in the fifth round of a scheduled 10-rounder.

Argentina’s Lopez (36-2-1, 21 KOs) blasted Lopez with a quick right hook late in the fifth round that knocked Echeverria flat on his back. Mexico’s Echeverria (21-9, 18 KOs) was counted out and the fight was stopped with just one second to go in the fifth round.

Following a slow start, Lopez knocked down Echeverria twice during the fourth round.

A short, straight right hand by Lopez dropped Echeverria the first time. Toward the end of the fourth round, a sweeping left hook by Lopez caught Echeverria on the side of his head and sent him to his gloves and knees.

Vergil Ortiz Jr.’s hometown fight Saturday night afforded Alex Rincon an opportunity shine near his hometown, too.

The unbeaten southpaw knocked out Joel Guevara in the second round on the Ortiz-Antonio Orozco undercard in Grand Prairie, Texas. Rincon, a 24-year-old junior middleweight prospect from nearby Carrollton, Texas, buzzed Guevara twice in the first round and dropped him early in the second round.

Rincon’s combination of a left to the body and a right hook to the head started sending Guevara to the canvas early in the second round. Rincon (6-0, 5 KOs) landed a right and a left up top as Guevara was falling.

Guevara (4-6-1, 3 KOs), of Charleston, West Virginia, fell flat on his back, underneath the bottom rope. He didn’t attempt to get up before the referee stopped the action 58 seconds into the second round.

Following Rincon’s win, Travell Mazion recorded a first-round knockdown and comfortably beat Jeremy Ramos by unanimous decision in an eight-round junior middleweight match.

Mazion (15-0, 12 KOs), of Austin, Texas, won by scores of 80-71, 78-73 and 78-73. The 24-year-old prospect fought for the first time 10 months, a layoff caused by a biceps injury.

Mazion mostly controlled the action with his jab and athleticism. He also landed the flashier, flusher punches on the Ramos (11-7, 4 KOs), of Colorado Springs, Colorado.

Mazion’s left hook to the side of Ramos’ head sent Ramos to the canvas with just over 40 seconds to go in the first round. Ramos reached his feet and survived the final 30 seconds of that opening round.
