Argentina’s first winner of the US Open at Oakmont, holding his nerve to win by a stroke as a hunting Tiger Woods and another former US Open Champion Jim Furyk chased down the home straight.

Has three victories on the European Tour, the 2001 Argentina Open, the 2002 Benson and Hedges International and the 2005 BMW PGA Championship. It seemed he would be happy at the upper end of the rankings for a few more years, until that fateful US Open win.

Now looking much more confident, though a 73 on Friday at Carnoustie set himback.
