Rising heavyweight boxer Joe Joyce gave a textbook demonstration on how to deliver a knockout via hook shot

• Joe Joyce clubbed Joseph Parker to the floor with a punch-perfect left hook Saturday.
• The 37-year-old has built a sneakily good boxing résumé and is a worthy title contender.

Joe Joyce continued his gradual march to the top of heavyweight boxing's mountain by thumping Joseph Parker into submission with an 11th-round knockout Saturday.

Joyce bested Parker at the AO Arena and his win — the 15th of his pro career — opens a debate as to whether he's a top-five heavyweight, or if he's now cracked the top three.

Parker hit Joyce with everything he could, landing 147 shots from 566 attempted, according to Compubox data sent to Insider, and thumped the Brit with hook shots and uppercuts in a back-and-forth third round.

It is testament to Joyce's punch resistance that he never appeared fazed by Parker's offensive weaponry, and even left the ring looking like he'd barely been hit, despite the punch statistics telling a different story.

Joyce, a boxing paradox, doesn't look too active or powerful, yet he landed 308 of his 844 punches on Parker and, with the weekend knockout win, has now finished 14 of his 15 opponents to date.

He has a deceptive, bruising, and cumulative type of power that wears people down until they can take no more.

And few heavyweights in the sport could stand up to what he delivered in the penultimate round, when he lashed a left hook onto Parker's chin.

Joyce would be formidable opposition for anyone in boxing

Joyce, 37, has built a sneakily good résumé already, having beaten Bryant Jennings, Daniel Dubois, and Carlos Takam in a short space of time. Giving Parker — a former WBO world champion — the most brutal defeat of his career, though, ranks as the most impressive thing Joyce has done in pro boxing so far.

With it he has proven to be ready for a world title shot, against either the WBC champion Tyson Fury, or the unified WBA, WBO, and IBF king Oleksandr Uysk.

Yet there are other intriguing bouts out there to make.

Fighting concussive puncher Deontay Wilder would be the combat sports version of an unstoppable force, in Wilder, against the immovable object, in Joyce.

Wilder's power, which has floored every opponent he has ever faced, could be the thing that can finally make Joyce wilt.

However, if Joyce's punch resistance can withstand Wilder's shots then he could eventually walk the American down for a late finish of his own.
