NEWARK, New Jersey – Troy Isley hit Roy Barringer with every power punch in his arsenal Saturday night, but Barringer was able to last all eight rounds with the undefeated middleweight prospect.

Isley was the more active, accurate puncher throughout their bout, though, and easily won a unanimous decision on the Shakur Stevenson-Shuichiro Yoshino undercard at Prudential Center. Judges John McKaie (80-72) and Paul Wallace (80-72) scored their fight a shutout for Isley, who won 79-73 according to judge Mark Consentino.

Isley, of Alexandria, Virginia, moved to 9-0. He went the distance in a third straight fight. Barringer, of Toledo, Ohio, slipped to 9-4 (6 KOs).

Isley drilled Barringer with a right hand early in the fourth round, but Barringer took it well. That was an indication of what was to come over the final four rounds.

Isley consistently landed the flusher punches, but Barringer was able to absorb those shots without going down. Barringer clearly lost, but he displayed toughness by going the distance.

Isley and Barringer traded hard shots toward the end of the second round. Isley tried hit Barringer after the bell sounded to end the second round, which drew a harsh warning from Fitch.

Barringer landed a left to Isley’s body during the first round, but Isley responded by landing several hard right hands that got Barringer’s attention. Isley continued to land rights and left hooks during the opening round.

Earlier Saturday night, Kelvin Davis remained undefeated a few fights before his brother’s televised bout.

The 26-year-old southpaw, an older brother of 2021 Olympic silver medalist Keyshawn Davis, defeated Nelson Morales by unanimous decision in their six-round welterweight fight. Judges Mark Consentino (60-54) and John McKaie (60-54) both scored their one-sided fight a shutout for Davis, who won 59-55 on the scorecard of judge Paul Wallace.

Davis (8-0, 5 KOs), of Norfolk, Virginia, started to separate himself from Morales in the third round, when he landed left hands that made Morales hold him and bloodied Morales’ nose. Morales mostly played it safe in the final three rounds and often attempted to tie up Davis.

Morales (3-5, 0 KOs), of Scranton, Pennsylvania, has lost four fights in a row.

In the bout before Davis’ victory, Jaylan Phillips thought he clearly had done enough in their third fight to beat Antoine Cobb.

When their third draw in as many fights was announced by ring announcer Mark Shunock, a dejected Phillips shook his head. McKaie scored all four rounds of their welterweight bout for Phillips, who won 40-36 on McKaie’s card.

Consentino and Wallace both scored their fight even, 38-38 apiece, thus they settled for a majority draw in the first fight on the Stevenson-Yoshino undercard.

Phillips, a taller southpaw, suffered a cut over his right eye in the first round, during which Cobb connected with multiple right hands that backed him up. Phillips boxed well in the second, third and fourth rounds and appeared to buzz Cobb with two left hands in the final round.

It still wasn’t enough to convince two of the judges he won.

Chicago’s Cobb (1-0-3, 1 KO) and Phillips (1-2-3, 1 KO), of Ebro, Florida, fought to a majority draw in their first four-rounder last April 30 on the Stevenson-Oscar Valdez undercard at MGM Grand Garden Arena in Las Vegas. Their four-round rematch resulted in a split draw September 23 on the Stevenson-Robson Conceicao undercard at Prudential Center.
