Mayelli Flores Rosquero W10 Nazarena Romero ... Mexico has a new champion. On the ProBox undercard from Kissimmee, Florida, Mayelli Flores Rosquero won the WBA junior featherweight championship, handing previously unbeaten Nazarena Romero her first loss by split decision. Official scores were 96-94 (twice) for Rosquero and 98-92 for Romero. Rosquero is listed at 4'11", 122 pounds, but she maintained a high work rate throughout the ten two-minute rounds. Roquero is 13-1-1, with the one defeat coming in a failed 2022 bantamweight title bid vs. Yuliahn Luna Avila. The Argentinean Romero landed more punches in the fight but congratulated both Rosquero and, surprisingly, the judges for awarding Rosquero the decision. Romero (14-1-2) appeared to suffer a broken nose in the second half of the fight.
