GREAT BRITAIN'S men secured their first win of their Olympic campaign on Tuesday night with a 9-1 thrashing of Brazil with five goals coming in the last 15 minutes.

The hosts, ranked a lowly 30th in the World, got off to a dream start, netting their first-ever goal in the Olympics thanks to a penalty corner routine converted by Stephane Vehrle-Smith.

GB, whose had Pinkneys Green resident Nick Catlin in midfield and former Reading star Simon Mantell on the subs bench, soon drew level through Adam Dixon in the ninth minute. The goal was Britain’s 200th in Olympic history.

Three minutes later skipper Barry Middleton gave his side the lead and from then on GB took control of this group match.

Home keeper Rodrigo Faustino made a string of top drawer saves, but was unable to prevent Ashley Jackson making it 3-1 and Harry Martin added the fourth as the game headed into the final quarter.

Next to score was Sam Ward, who slotted the ball between the legs of Thiago Bomfim, who had replaced Faustino in goal.

With 10 minutes to go, head coach Bobby Crutchley removed goalkeeper George Pinner, opting to play with 11 outfielders in an attempt to improve GB's goal difference following their 4-1 defeat by Belgium and 2-2 draw with New Zealand.

The tactic paid off almost immediately with Middleton netting his second and his side's sixth.

Gleghorne added his name to the scoresheet before Middleton was denied a hat-trick by a defender’s foot on the line, but from the resultant penalty stroke Jackson made no mistake.

Soon afterwards Jackson set up Ward to make it 9-1.

Britain’s next match is tomorrow morning (Thursday, 12.30am) versus Australia, who are top of the World rankings.

Middleton said: "We will have to defend a lot more but we did a lot of things right against Brazil; we need to keep that up.”
