Errol Spence mixed up his attack on Leonard Bundu: He landed 8 jabs per round and 46 of his 135 landed punches were body shots. Spence landed 64% of his power shots and closed the show by landing 15 of 19 power shots in round six. Thurman landed 47% of his power shots in his decision win over Bundu.
With the knockout, Spence Jr. becomes the mandatory challenger for undefeated welterweight Kell Brook and showed his willingness to step in the ring with Brook.
In a prime spot that immediately followed the U.S. Men's basketball team winning Olympic gold in Rio, the Dallas-native started patiently, measuring his opponent with steady jabs. Bundu came ready to fight and tried to make it difficult for Spence Jr. by switching stances and attacking from awkward angles.
Spence Jr. began to pick up his power punching as the rounds went on and started to connect with left uppercuts and hooks. After round four, Bundu returned to his corner with swelling beginning to show up over his right eye.
The dominance with his power punches began to wear Bundu down as the fight entered the sixth. After seemingly scoring a knockdown, which was ruled a slip by referee Johnny Callas, Spence Jr. quickly pounced on Bundu and trapped him in the corner.
It didn't take long for Spence Jr. to take advantage as he hit Bundu with a hard left uppercut and followed with a crushing right hook that put Bundu on the mat for good and forced the referee to stop the fight at 2:06 of the sixth-round.
