Jeffrey Fontanez looked sharp in registering a fourth-round knockout over John Nater in their Telefutura-televised main event Saturday evening in Juncos, Puerto Rico.
Fontanez weighed 134 lb., while Nater came in at the lightweight limit of 135 lb.
Action in the early going never really developed beyond a high-speed chess match. The 20-year young Fontanez showed flashes of brilliance, rattling off combinations to the body and the occasional flurry upstairs. For the most part, he was content to box and move early on, only engaging when Nater felt compelled to press with his attack.
The best of those moments came in a power-punching third round, when Fontanez was momentarily shaken after getting clipped upstairs.
It was the very sequence required to awake a sleeping giant.
Nater never knew what hit him in round four. A vicious counter left hook to the body floored the Bayamon native, prompting Fontanez to race to his corner and crouch in anticipation of finishing off his fellow Boricua in the event the fight would continue.
While Nater managed to beat the count, he was in no condition to continue. This much was recognized by the referee, who waved off the fight without another punch being thrown.
The official time was 0:46 of round four.
Fontanez improves to 9-0 (8KO) with the win. The Caguas-based knockout artist has now managed nine wins in the span of 14 months, with a bright future ahead. Nater sees a two-fight win-streak come to an end as he falls to 11-4-1 (8KO).
The televised co-feature saw Braulio Santos maintain his perfect record after scoring a second roung stoppage over John Alberto Molina (32-2-3). A straight right hand turned Molina's legs into rubber, as he wobbled around the ring even after beating the count.
The referee wisely waved off the fight, with the official time at 1:05 of round two.
Santos has won all four of his bouts in 2012 as he improves to 8-0 (7KO).
A terrific swing bout saw Miguel Tapia dig deep to edge out Jose Ruiz in their four-round affair. The action was non-stop from the opening bell, with Tapia's slightly greater rate of activity resulting in a 39-37 sweep on the three scorecards.
Tapia wins his second straight in improving to 6-1-1 (3KO). Ruiz falls to 2-2 (0KO), with all four his career bouts - all in 2012 - going the four-round distance.
