Apparently, even Roger Federer, with his record 16 Grand Slam titles, was in need of some advice on a wet and windy Wednesday at the French Open. Forced off court by two rain delays and "pushed," as he put it, by a player with a career record below .500, Federer turned to Swiss Davis Cup captain Severin Luthi for words of wisdom during the breaks. Told to be more aggressive early and then to use more drop shots late, Federer survived for 7-6 (4), 6-2, 6-4 victory over Alejandro Falla in the second round. "Those were good things he told me," said the top-ranked Federer, the French Open's defending champion for the first time. "Those little details make a crucial difference." http://sports.espn.go.com/sports/tennis/french10/news/story?id=5221097
