The call to action was for Brandun Lee face the type of opposition to truly gauge his career potential.

It was a test he passed with flying colors.

The streaking junior welterweight knockout artist registered one for the highlight reel, tearing through Philadelphia’s Samuel Teah en route to a 3rd round knockout win. Lee scored two knockdowns, the latter which prompted an immediate stoppage at 1:43 of round three in their Showtime-televised main event Wednesday evening at Mohegan Sun Arena in Uncasville, Connecticut.

Lee has become well-known for his finishing power. It was Teah who landed the bout’s first significant punch, however, as he connected with a clean right hand on the chin. Lee took the shot well, responding with a right hand of his own. Teah stood his ground, pumping a heavy jab and looking to land in combination. Lee fought patiently, throwing angled right hands and left hooks.

Teah managed to shoot his jab to start round two. Lee remained poised, not wasting any punches or movement as he eventually swung momentum back in his favor. An overhand right to the temple briefly froze Teah in place, though with Lee unable to fully capitalize. Lee continued to throw power punches until the bell.

Lee emphatically closed the show in round three, though not from a lack of resistance from his opponent. Teah was a bit too game to work on the inside, dearly paying the price as he was caught with a three-punch combination to send him crashing to the canvas for the first time in his career. Teah somehow beat the count, though he was far better off staying down.

That part would be accommodated mere moments later. Lee sensed the knockout was well within sight but didn’t force it. Teah left himself open for a booming overhand right which put him flat on the back.

Referee Johnny Callas didn’t even bother to count, instead immediately calling for medical attention to tend to the fallen Teah (17-4-1, 7KOs).

Lee improves—in every sense of the word—to 22-0 (20KOs). The 21-year old from La Quinta, California has yet to be extended beyond the fourth round of any given fight, though doing so against opponents who’d never previously been stopped. The win was his fourth on Showtime’s ShoBox series, though it’s clear that he has graduated to the contender level.

Lee has now stopped his last 13 opponents dating back to June 2018.
