Day 6 at the French Open saw the end of "The Week of La Monf," as Gael Monfils bowed out of the tournament to Tommy Robredo.
But that wasn't the only outcome of note. John Isner did something he's never done before to become the last American man standing, and Rafael Nadal continued to struggle in the cold, heavy conditions. The forecast calls for warmer temperatures over the next week, so buck up, Rafa!
Here are some of the best pictures from Day 6.
Gael Monfils: The Frenchman couldn't convert any of his four match points against Tommy Robredo, and he was broken to 5-5 while serving for the match in the fourth set. Monfils responded by grabbing a seat and staring off into space -- not unlike the rest of us. (Martin Bureau/AFP/Getty Images)
Marion Bartoli: She hasn't been playing at her best, but she's been battling. This time, Bartoli beat Mariana Duque-Marino 7-6 (5), 7-5. She'll face 2010 French Open champion Francesca Schiavone next. (Patrick Kovarik/AFP/Getty Images)
Rafael Nadal: Did my invitation to the gun show get lost in the mail? International postage can be tricky. (Clive Brunskill/Getty Images)
Ana Ivanovic: The Serb has quietly advanced to the fourth round and will face Agnieszka Radwanska. (Matthew Stockman/Getty Images)
John Isner and Ryan Harrison: Isner came back from a two-sets-to-love deficit to win for the first time in his career. He outlasted fellow American Harrison 5-7, 6-7 (7), 6-3, 6-1, 8-6. If Isner beats Tommy Haas on Saturday, he would overtake Sam Querrey as the No. 1 American. (Christophe Ena/AP)
Viktor Troicki: Quick! Someone grab a camera! But seriously, you could probably see that shirt from space. (Julian Finney/Getty Images)
Serena Williams: She cruised past Sorana Cirstea 6-0, 6-2, and she was still fired up after winning a long rally late in the second set. (Clive Brunskill/Getty Images)
Roger Federer: He knocked off Julien Benneteau 6-3, 6-4, 7-5 with his eyes closed. He'll play Gilles Simon next. (Michel Euler/AP)
Eugenie Bouchard and Maria Sharapova: With Bouchard's loss to Sharapova and Monica Puig's loss to Carla Suarez Navarro, the teens are all out of Paris. (Matthew Stockman/Getty Images)
Francesca Schiavone: The hair can hide the face, but nothing can hide that smile. Schiavone has found some of that Roland Garros magic and is into the fourth round after a 6-1, 4-6, 6-3 win over 21st-seeded Kirsten Flipkens. (Petr David Josek/AP)
