PBC on NBC results: Errol Spence smashes Phil Lo Greco in three

It's never easy to fight on two days' notice, and Phil Lo Greco knew he was putting himself in a very tough situation when he decided to do just that. Making the uphill climb even steeper, he was stepping in to face arguably the best welterweight prospect in boxing, Errol Spence Jr, on tonight's PBC on NBC card.

Lo Greco (26-2, 14 KO) gave it what he had, but was overwhelmed early by Spence (17-0, 14 KO), taken apart in the second round before being dropped and stopped in the third at the MGM Grand.

Spence, 25, felt Lo Greco out in the opening round, but when "The Italian Sensation" came out more aggressive for the second, Spence began to systematically take him apart, thrashing him with accurate and vicious body shots, and mixing in the occasional stinger upstairs, too.

Lo Greco, 30, went down about 40 seconds into the third round after an accumulation of shots, first more body blows, and ending with a short right hook off the side of his head. He lasted about a minute longer, as Spence hunted him without getting careless. With Lo Greco pinned against the ropes and taking more clean shots, referee Robert Byrd stepped in to stop the contest at 1:50 of round three.

What did you think of Spence tonight, and how far off do you believe he is from becoming a serious contender at 147?
