LONDON, July 30: Britain, Ireland and the revitalised American team are all off to a perfect start in the Olympic boxing tournament.

Jose Ramirez and Errol Spence won their opening bouts Sunday night to improve the Americans to 4-0, while Freddie Evans and Josh Taylor rode the home crowd’s raucous cheers to a 3-0 start for Britain.

Welterweight Adam Nolan then added a win in the late session, pushing Ireland’s record to 3-0.

Welterweight Custio Clayton also notched Canada’s first Olympic win in eight years on an eventful day at ExCel.

The young Americans fought nearly back-to-back, and both produced impressive wins over seasoned amateur veterans.

Ramirez pressed the action and fought out of trouble throughout a 21-20 win over France’s Rachid Azzedine while Spence had an easier time in a rougher fight, persevering through questionable tactics by three-time Brazilian Olympian Myke Ribeiro de Carvalho for a 16-10 victory.—AP
