German Andrea Petkovic says Hall of Famer Steffi Graf has told her she’s going to attend one of Germany’s upcoming Fed Cup ties. Since retiring in 1999, 22-time Grand Slam champion Graf has rarely made appearances at pro tournaments. "The last time I talked to her was during Fed Cup. She called our Fed Cup captain, Barbara [Rittner], during the dinner before it started and wished us all good luck," said Petkovic, who reached her first Roland Garros quarterfinal with a three-set win over Maria Kirilenko. "She told us that she's going to come to one of the next Fed Cup ties, so I really hope I can see her again there. And maybe I'm planning on before the U.S. tour going to Las Vegas again [where Graf lives with her husband, Andre Agassi], so I should see her there."
