PBC on Spike: Adonis Stevenson blows out Tommy Karpency, Errol Spence beats down Chris van Heerden

Few gave Pennsylvania's Tommy Karpency any chance against WBC Light Heavyweight Champion Adonis Stevenson in the main event of Premier Boxing Champions double-header last night.

As it turns out, those few were very, very wrong.

The power-punching Quebecois absolutely demolished Karpency (25-5-1, 14 KO), rattling him in the first round and dropping him in the waning moments of the second before finishing him moments into the third. Simply put, Stevenson's (27-1, 22 KO) power, speed, and overall boxing acumen were all levels above the Pennsylvanian's.

A brutal left cross destroyed Karpency's equilibrium and follow-up shots earned the first knockdown, while another big left forced Karpency to faceplant. Though the American beat the count, the referee mercifully stepped in.

After the fight, Stevenson called out Sergey Kovalev in what has become a tradition between the two. Odds are we're never going to see this one; more likely, Stevenson takes on the winner of the upcoming WBC eliminator between Eleider Alvarez and Isaac Chilemba.

The co-main event featured significantly better matchmaking, but wasn't much more competitive as top prospect Errol Spence, Jr. battered the very capable Chris van Heerden for an eighth-round stoppage. Spence (18-0, 15 KO) controlled the fight from the beginning with his killer jab and bodywork while limiting van Heerden (23-2-1, 12 KO) to sporadic body shots and posturing. Spence dropped him in the seventh with a hard shot behind the ear, followed by a nasty body shot, then forced a stoppage in the following round with brutal shots along the ropes.

This was a step up for Spence, but he looked phenomenal; I'd love to see him against a Top 10-ranked opponent in the near future.

The finish also made time for a swing fight, in which prospect Prichard Colon knocked out former champ Vivian Harris in four.
