London 2012 Olympics: "Real grit" helps Great Britain beat Spain to win Tri Nations tournament Two early goals, which came courtesy of Reading forward Jonty Clarke and captain Barry Middleton, gave GB a lead they would not surrender, despite Spain pulling one back just before halftime through Pau Quemada. Clarke opened the scoring in the 11th minute, profiting from an Ashley Jackson throughball which was pushed into his path by Rob Moore. Middleton doubled the lead eight minutes later, steering the ball past Spanish goalkeeper Francisco Cortes. Spain set up a nervous second half for GB when Quemada unleashed an unstoppable penalty corner drag flick past James Fair four minutes before the interval. And the visitors were forced to endure four Spanish penalty corners in the second period as the hosts piled on the pressure in search of an ultimately elusive equaliser. Despite having one or two half-chances on the counter - most notably through an inviting Dan Fox cross and, later, an Ashley Jackson shot - Great Britain spent much of the second half on the back foot, and were relieved when the final whistle signalled their victory. GB are due to return to this country on Thursday, and move into the Olympic village on Sunday 22 July. Meanwhile Spain face India on Wednesday in the final match of the tournament - a dead rubber, but one in which both sides will be seeking a confidence booster before the Olympics.
