When Robin Soderling knocked off Rafael Nadal in the 2009 Quafterfinals, Nadal had never lost a match at the French. To this day, it remains his only loss on the red clay, his career mark there 46-1.
Soderling entered the tournament seeded 23rd and had never advanced past the third round in 21 previous Grand Slam appearances. He eventually advanced to the final where he lost to Roger Federer in straight sets.
Soderling used his win over Nadal and subsequent advancement to the 2009 final as a springboard to an excellent finish to the season. He advanced to the quarterfinals at the US Open that fall and qualified for the year-end championship in London.
Federer had a streak of reaching 21 consecutive Grand Slam quarterfinals entering the 2010 French Open. After losing the first set, Soderling used a break in each of the last three sets to shock Federer in four to reach his second straight French Open quarterfinal.
He overcame a two-sets-to-one deficit against Thomas Berdych in the semifinal before losing to Nadal in straight sets in the final.
