Michael Osumah TKO4 Sergio Gil... Nigerian power took center stage in Las Vegas, where unbeaten junior middleweight Michael Osumah scored a fourth-round technical knockout of Argentina’s Sergio Gil (22-16-2) on Saturday night at the The Cosmopolitan. From the opening bell, the difference in firepower was undeniable. Osumah (11-0, 10 KOs) wasted no time asserting himself, taking command of center ring and using his reach to break down Gil’s guard. The Argentine veteran attempted to lean on his experience to weather the storm, but Osumah’s hand speed began to crack that defense as early as the second round. The beginning of the end came in the third, when a left hook from Osumah sent Gil reeling into the ropes. Though the Argentine showed grit to survive the round, the damage was done. By the fourth, it was all one-way traffic. A barrage of unanswered combinations forced the referee to step in and wave it off at the 1:45 mark, saving Gil from further punishment.
