Serena Williams survived a first-set scare before defeating Russia's Vitalia Diatchenko 2-6, 6-1, 6-0 to reach the second round of the French Open on Monday. The 37-year-old American, who is attempting to equal Margaret Court's all-time record of 24 Grand Slam titles, racked up her 800th career main draw win with her victory in front of a half-full Court Philippe Chatrier.
