Third seed Guillermo Coria set up the first ever all-Argentine final at the French Open as he ended the hopes of Briton Tim Henman with a 3-6 6-4 6-0 7-5 win to reach his first grand slam final.
Coria, who lost in the semi-finals last year, recovered from a set and a break down as he set up a final against unseeded Gaston Gaudio, who earlier beat another Argentine, David Nalbandian, in straight sets.
For just over an hour, it looked as if ninth seed Henman, who had never previously been past round three in Paris, would pull off a huge shock as he served and volleyed his way to a 6-3 4-2 lead.
But once Coria had broken back for 4-3, the Argentine took control, winning 13 games in succession to take the third set and lead 3-0 in the fourth.
Against the odds, Henman suddenly regained his form, reeling off five straight games, only to be broken when serving for the set at 5-4 and Coria then broke again two games later to clinch victory.
Guillermo Vilas was the last Argentine to reach the final at Roland Garros, in 1982.
