The Lionhearts' 4-1 victory gives them a five-point lead over the second-placed Americans in Group B ahead of their clash with the Morocco Atlas Lions in two weeks’ time.

European Confederation Boxing Championships silver medallist Muhammad Ali got the home side off to a strong start against USA Knockouts’ 23-year-old Gaurav Bidhuri at flyweight.

His lightening combinations and long, straight punching delivered a unanimous judges’ decision after five rounds.

The Americans were soon back on level terms though after winning the battle of the welterweight southpaws.

Lionhearts' promising debutant Cyrus Pattinson was stopped in his tracks in the third round of what had, up to then, been a balanced contest with fellow debutant Ardreal Holmes.

Wales’ European Confederation champion Joseph Cordina continued his strong run of form with a confident display at lightweight against Knockouts debutant Bruce Carrington.

Cordina was focused throughout, comfortably taking all five rounds for a unanimous points decision to give the hosts an advantage they would refuse to let slip.

Lionhearts' light heavyweight Joshua Buatsi had his opponent Souliman Abdourachidov on the canvas as early as the first round.

Abdourachidov battled back well in the second and third of a gripping encounter, but it was Buatsi who seized control, delivering a massive left in the fourth that put his French rival down for the final time as the referee awarded the home side the TKO and a deserved win on the night.

That left Joe Joyce to round-off the action in emphatic style as last year’s super heavyweight star returned to the WSB fray with a big left hook in the opening seconds and then had Knockouts’ Brandon Lynch on the canvas inside the first minute.

WSB action is scheduled to resume tomorrow as Morocco Atlas Lions face Mexico Guerreros in Group B and Azerbaijan Baku Fires go up against Astana Arlans Kazakhstan in Group D.
