The British Lionhearts maintain their position at the top of the Group B of the World Series of Boxing (WSB) after whitewashing the Mexico Guerreros at York Hall in London.

Having achieved hard fought 3-2 victories over the USA Knockouts and Morocco Atlas Lions in their opening fixtures of the season, the Lionhearts were aiming to continue their impressive start in front of a home crowd.

Galal Yafai, making his WSB debut, was able to get the Lionhearts off to an ideal start in the 46-49 kilogram light flyweight division against Joselito Velazquez.

With the opening round have proving an even contest between the two boxers, Velazquez suffered a dislocated shoulder, ending the contest prematurely.

The Lionhearts closed on the victory when Qais Ashfaq defeated Sergio Chirino in the under 56kg bantamweight division by a unanimous points decision.

Two judges scored the decision 50-45 in the Briton’s favour, while the third gave him the verdict 49-46.

Raul Curiel, whose performances in last season’s WSB guaranteed himself a place at this year's Olympic Games in Rio de Janeiro, was required to win his 64kg light welterweight clash with Pat McCormack to keep the Guerreros hopes alive.

He was unable to defeat the 2015 European Championship silver medallist, however, McCormack being given a unanimous victory at the conclusion of the bout.

Under 75kg middleweight Antony Fowler added further gloss to the score by replicating his team-mate's feat against Misael Rodriguez, before Lawrence Okolie defeated Jared Barraza by a technical knock-out in the 91kg heavyweight division to seal the 5-0 win.

The result will keep the Lionhearts clear at the top of Group B at the end of the weekend’s action, regardless of the outcome of the USA Knockouts tie tomorrow against the Morocco Atlas Lions in Casablanca, where the hosts will continue their search for a first win.

The Azerbaijan Baku Fires will also be in action as they host the Puerto Rico Hurricanes tomorrow, where they will be looking for their second straight win, having defeated the Uzbek Tigers in their last tie.

Having been whitewashed in their opening Group D tie against the Uzbek Tigers, the Hurriacanes will be hoping to secure a first victory.
