An emotional Del Potro soaked up the incredible atmosphere on Court Suzanne-Lenglen as he captured victory 7-6(5) 5-7 6-3 7-5. "It’s tough to speak now,” he said through tears. “I have had three surgeries on my left wrist and I was close to quitting. This is so good for my team and my family. It was very important to have the support of my family and friends and the love of you guys, you make me so happy. I am so proud to be playing tennis. I feel at home here. Merci beaucoup.”
