Two months shy of her 39th birthday, Lourdes Juarez did just enough to prevail with a 10-round majority decision win over Yesica Nery Plata and make a successful second defence of her WBC junior flyweight title.

Neither woman could be confident of a positive outcome at the final bell, though this closely-contested world title attraction proved a fitting end to Most Valuable Prospects 16 bill at Convention Center in South Padre Island, Texas. The four-fight main card was streamed worldwide on DAZN, following three hours' worth of prelim action.

After one judge scored it 95-95, the other two saw the Mexican veteran winning by a round (96-94) to inflict a narrow third career defeat for her younger compatriot, who began fast here in ending a 22-month layoff.

Her last outing was a 10-round split decision win over newly-unified world champion Sarah Bormann, who moved down a division and unified the IBF/WBA strawweight titles with a contentious split nod over Yuko Kuroki (25-9-2, 10 KOs) in Hamburg, Germany on Saturday.

Nip-and-tuck action between the pair saw them trade rounds, Nery Plata (30-3, 3 KOs) working well behind her jab and body work while Juarez's increased punch volume prompted the challenger forward into close-range exchanges.

Juarez (39-4, 5 KOs) fared well on the inside while Nery Plata landed clean at distance, though the two-minute rounds flew by and were difficult to score as both enjoyed periods of success without being dominant.

Dominance certainly describes unified IBF, WBO middleweight champion Desley Robinson's evening though. She scored a second-round technical knockout win over Logan Holler, 1:08 the official time as the Australian visitor's first stateside appearance was a memorable one.

In truth, there was a clear gulf in quality between them and this world title opportunity was over before South Carolina-based Holler knew it. Holler, three years her junior at 34, also suffered a career-first stoppage defeat here after absorbing a body-head combination she didn't see coming, which stumbled her back to the ropes early in the second frame. 

Robinson (11-3, 4 KOs) disguised it beautifully, right to the body and left hook through her guard, with a right hand to follow as the referee wasn't fast enough to react and send the champion to a neutral corner. Eventually he did, Holler looked unsteady and dazed before a vicious barrage saw the fight waved away moments later.

Elsewhere on the card, Texas' own Omar Juarez used body punching and relentless output to earn a 10-round points win (99-89, 99-89, 97-91) over Omar Rosario in a must-win junior welterweight matchup for both.

Puerto Rico's Rosario (14-3, 4 KOs) was deducted two points for holding, as Juarez (20-2, 7 KOs) came into his own after a competitive first-half of their 140-pound clash.

Highly-rated super middleweight prospect Ronny Alvarez returned to his familiar finishing ways with a fifth-round stoppage (2:38) over San Antonio's Bruno Pola Ruiz to kick off the main card's action.

Cuban southpaw Alvarez (5-0, 4 KOs) went the six-round distance against a durable Ryan Adams in Orlando last month, but the 21-year-old needed one round fewer this time around to dismiss Ruiz (10-4-1, 9 KOs).
