Another week, another set of sparring partners at Hayemaker HQ, as American Deontay Wilder and Poland's Mariusz Wach arrive in the capital ahead of sparring duties with Britain's former WBA world heavyweight champion David Haye.

The tall and talented pair, both world-class heavyweights in their own right, follow hot on the heels of Alexander Dimitrenko and Richard Towers, who will remain a go-to sparring partner in the final weeks of training.

Standing at 6'7 and 250-pounds, Wach is the current WBC international heavyweight champion and a man most famous for going the full twelve rounds with undisputed world heavyweight champion Wladimir Klitschko in 2012. As well as being renowned for his granite chin, he holds wins over Tye Fields, Kevin McBride and Jason Gavern.

The 6'8 and 225-pound Wilder, meanwhile, is undefeated in 29 pro bouts, winning every single one of them via big knockout. Born in Tuscaloosa, Alabama, the former 2008 Olympic bronze medallist is considered America's next great heavyweight and, naturally, one of the heaviest pound-for-pound punchers in the sport today.

“I couldn't ask for better sparring, to be honest,” said Haye. “Dimitrenko and Towers have been fantastic – both tall and awkward – and I'm looking forward to seeing what problems Wilder and Wach can present me with.

“I've followed Deontay for most of his career, ever since we first sparred in 2010 (pictured), and I've been so impressed by his progress. He seems to get better and better every time I see him fight, and just as people start expecting his knockouts to dry up, he keeps knocking opponents down. He has genuine, one-punch power, and that's an exciting thing for the heavyweight division.

“Wach is as tough as any heavyweight in the world and has a chin made of steel. I watched his brave effort against Wladimir Klitschko last year and couldn't believe the punishment he took during the fight. He was eating big right hands and left hooks without blinking, never once taking a backwards step.”
