BKB called it one of the quickest knockouts in the promotion’s history, while the result stood as the fastest finish on a 12-fight event dominated by early stoppages. Ten bouts ended inside the distance, with seven of those finishes coming in the first round.
Vandermeer entered the contest with a 2-2 bare-knuckle record and two knockouts. Fuentes arrived unbeaten at 4-0, with two knockout wins, making the rapid conclusion a major reversal of the pre-fight records. Both men were close in weight at the official weigh-in, with Fuentes listed at 198.4 pounds and Vandermeer at 199 pounds.
The victory moved Vandermeer to 3-2 with three knockout wins, while Fuentes took the first defeat of his bare-knuckle career and fell to 4-1. It was a short outing, but the timing gave Vandermeer a clear calling-card moment in a division where a clean opening exchange can rewrite a night.
Vandermeer’s finish came during a BKB 58 card built around three title contests and the bare-knuckle debut of former Olympic gold medallist and world boxing champion Yuriorkis Gamboa.
In the main event, Gustavo Trujillo retained the BKB heavyweight championship by stopping late replacement Mick Terrill with a body punch at 2:59 of the second round. Trujillo’s record rose to 9-0, with all nine victories by knockout. Terrill stepped in after original challenger Mark O’Neill was unable to travel because of visa issues.
For Vandermeer, though, no one had time to settle into the fight. Nine seconds was enough to leave Miami with the quickest knockout of BKB 58 and a debut that will travel far beyond the final bell.
