With the 2013 French Open women's final set and just four men left to claim their shot at this year's slam, there has been plenty of memorable tennis played at Roland Garros thus far.
From stunning upsets like Gael Monfils' early ouster of Tomas Berdych and Bethanie Mattek-Sands' win over Li Na in the second round to the expected dominance of Serena Williams and Novak Djokovic—we've witnessed what makes the French Open a special tournament.
Heading into the final days of the tournament, here are the three performances that have been the most impressive thus far based on significance and excellence.
3.Tommy Haas Outlasts John Isner
There are thee guarantees in life—death, taxes and John Isner engaging in really long tennis matches. Isner is no stranger to marathon matches. His 2010 Wimbledon match with Nicolas Mahut is the longest in tennis history at just over 11 hours.
Isner's match with Haas wasn't quite that long, but it did go five sets with multiple tiebreakers. It was another classic for Isner, but Haas came out on top.
The German contender hit 85 winners and kept mistakes to a minimum, committing just 43 unforced errors to his opponent's 58 in the four-hour, 37-minute match.
As Darren Cahill tweeted, this was just a fantastic match between two tennis warriors.
Haas went on to beat Mikhail Youzhny in straight sets to advance to the quarterfinals where he ran into Novak Djokovic. Still, the fact that the 35-year-old went toe-to-toe with a high-endurance player like Isner created one of the best performances of the tournament.
2. Jo-Wilfried Tsonga Upsets Roger Federer
Jo-Wilfried Tsonga has always been one of the more talented players outside of tennis' big four of Novak Djokovic, Roger Federer, Rafael Nadal and Andy Murray. His French Open upset of Federer may be the breakthrough victory he needs to be considered a serious threat to those big four.
The big Frenchman entered his quarterfinals matchup against Federer with a chance to make things interesting against the legend, but he did much more than that. Tsonga played a brilliant match and upset Federer in straight sets. According to ESPN Stats & Info, that's been a rare feat:
The fact that Tsonga won shouldn't be a surprise. He had come into the match without dropping a set at Roland Garros, and Federer had a grueling five-set match against Gilles Simon in the previous round.
What was surprising was that Tsonga made it look so easy. With a win over David Ferrer in the semis, Tsonga could be the breakout star at Roland Garros.
1. Serena Williams Blasts Sara Errani to Book Finals Trip
As if Serena's undefeated record on clay this year wasn't a big enough sign that she's ready to capture her first French Open title since 2002, she saved her best performance thus far for the semifinals against Sara Errani.
Williams didn't even take an hour to defeat Errani, who, by the way, had just defeated No. 4 player in the world Agnie Radwanska in straight sets herself. Grantland's Brian Phillips summed up just how great Williams' performance was:
Errani hit just two winners throughout the match and took one game as Serena cruised to a 6-0, 6-1 victory. That kind of domination shouldn't even be possible in the semifinal of a slam tournament, yet Williams made it look easy.
That kind of domination will be hard to top in her next match.
