Hamzah Sheeraz and Edgar Berlanga have built their careers on knocking out people.

In the 46 fights that make up their resumes, the pair has managed just 183 rounds between them. That means they average fewer than four rounds per fight.

But which of these knockout wins were the best? Ahead of their clash at the Louis Armstrong Stadium in Queens, New York, on the Ring III card, we take a look at both men’s top five wins.

Denny, European middleweight champion, was in the form of his life when he arrived at Wembley Stadium and many had suggested that Sheeraz might just need a bit of time to figure the southpaw out. He didn’t. Denny went down inside the first 10 seconds but managed to navigate through the rest of the round. However, with a minute left of the second, Sheeraz dropped Denny again with a left hook and referee Mark Bates waved it off.

This was a captain’s performance from Queensberry skipper Sheeraz in his 5v5 bout against undefeated "Ammo" Williams. The finish itself was not the prettiest but it was effective as a series of clubbing hooks sent Williams backing stumbling into the corner, giving referee Mark Lyson little choice but to wave it off.

There was only one winner in this battle of the unbeaten middleweights. Sheeraz floored Mytrofanov inside a minute of the first round and then put him down again with a ramrod jab with 60 seconds left of the opener. The Ukrainian somehow made it to the end of the round but the writing was on the wall and Sheeraz closed the show with a textbook right hand 35 seconds into the second.

This was Sheeraz’s first stoppage in the first round for five years and it came against the experienced former world title challenger in Williams, who had no reply from the onslaught. Williams had already been down twice and was on the verge of being badly knocked out when his coach Gary Lockett wisely threw in the towel.

Just four months after his controversial victory over Bradley Skeete, there was heavy pressure on Sheeraz as he returned to the ring in what was his middleweight debut. But capable operator Smith had no answer for Sheeraz’s power. A left hook lifted Smith off his feet in the first round but it was a right hand early in the second that finished the fight.

In his first fight after losing to Canelo Alvarez, the New Yorker got straight back to business, seeing off Gonzalez-Ortiz after just 151 seconds of the opening bell. A huge left hook put him down for the first time and, although he managed to climb back to his feet, he was stopped against the ropes moments later.

This was highlight-reel stuff from Berlanga in Orlando, as he booked his date with Alvarez in some style against McCrory. The sixth was all-action from both but, with McCrory against the ropes, Berlanga uncorked two stunning right hooks which sent the travelling Irishman sliding down to the canvas. He did his best to beat the count but the towel was already in.

Berlanga was 15-0 with all 15 wins coming inside the first round when he took on Sierra, who had never been stopped before. But The Chosen One seemed Hell bent on keeping that run going in Las Vegas and, with just 20 seconds left of the opener, he got his KO when a left hook dropped Sierra for the third time.

The 20-5-2 Bellows was tasked with somehow taking red-hot Berlanga beyond the first round, but he also failed that assignment. The Money Team member was boxing with ambition himself, but with just 79 seconds gone referee Robert Hoyle jumped in to stop the punishment with Berlanga unloading.

Of his famous 16-fight first round knockout streak, the one against 7-4 Hungarian Gyorgy Varju was the quickest and, at just 43 seconds, it remains his fastest ever. It is also one of his most explosive with a four-punch combination, finishing on a left hook, downing Varju heavily. There was no chance he could beat the count but referee Andrew Glenn completed it anyway.
