Olajuwon Acosta 'El Rayo' is poised to maintain his undefeated record against Ephraim Bui 'The Effect' in a Super Flyweight contest in Puerto Rico.

Olajuwon Acosta "El Rayo" face Ephraim at Palacio de Recreación y Deportes Germán "Wilkins" Vélez Ramírez, Mayagüez, Puerto Rico on Saturday, part of the 2026 Undetermined Weight Class season. Both fighters' recent records, methods of victory, and stylistic matchup factors are detailed alongside the prediction below.
ATS PREDICTION
Olajuwon Acosta "El Rayo" Win
Predicted: TKO Round 9-10
⚡87%
Olajuwon Acosta 'El Rayo' enters this bout with an impressive undefeated professional record of 15-0, including 10 knockouts, showcasing significant punching power and consistent winning form. He holds the WBA Continental Americas Super Flyweight title and has been active, securing a TKO victory in September 2025 and a unanimous decision in May 2025. Fighting in Mayaguez, Puerto Rico, Acosta will benefit from a home-crowd advantage at the 'UP Boxing Series: Choke de Campeones' event. Ephraim Bui 'The Effect' holds a strong record of 10-1 with 8 KOs; however, his sole loss came via unanimous decision in December 2024 against John Ramirez, indicating he can be outboxed by top-tier competition. Acosta's power, consistent activity, and home advantage make him the favorite to secure a decisive victory, likely by late-round stoppage or a clear unanimous decision.
SPREAD PREDICTION
Olajuwon Acosta "El Rayo" wins by KO/TKO (0)
85%
Given Olajuwon Acosta's high knockout ratio (10 KOs in 15 fights) and his reputation as a devastating puncher, a victory by knockout or technical knockout is a highly probable outcome. Ephraim Bui, while skilled, suffered a unanimous decision loss in his most recent high-profile fight, suggesting he can be vulnerable to sustained pressure. Acosta's aggressive style and power at Super Flyweight align well with a stoppage victory.
TOTAL PREDICTION
Over 7.5
75%
Both fighters possess significant knockout power, which might suggest an early finish. However, given Ephraim Bui's resilience in his decision loss and the potential for a competitive early-to-mid fight, the bout could extend into the later rounds before a potential stoppage or a decision. Acosta's most recent TKO win was in Round 4, but he also has 10-round and 8-round decision wins, indicating he can go the distance if needed. This pick assumes a competitive fight that likely goes beyond the midway point before a clear winner emerges.
