NOTTINGHAM, England -- Steffi Graf will fly home today from the Federation Cup for treatment of tendinitis in her shoulder and may miss Germany's remaining matches.
Graf, playing in pain and requiring on-court treatment, struggled to win her singles match yesterday against Patricia Hy of Canada, as Germany advanced to the quarterfinals of the 32-nation event.
"Steffi is taking the first flight in the morning to Essen to see a specialist, who will determine whether she can return to compete in the rest of the tournament," said team captain Klaus Hofsass.
The United States and top seed Spain also reached the quarterfinals with victories yesterday, along with Italy, Switzerland, Austria, Indonesia and Czechoslovakia.
Jennifer Capriati and Mary Joe Fernandez won singles matches in straight sets, as the U.S. team swept past Bulgaria, and Spain got three-set singles victories from Arantxa Sanchez Vicario and Conchita Martinez to defeat Australia.
"Steffi could hardly lift her arm above her shoulder," said German team doctor Hartmut Krahl. "She played the match at half-pace. She was obviously in a lot of pain."
Meanwhile, top-ranked Monica Seles, the subject of criticism by Graf for skipping the Federation Cup, said Graf should keep her opinions to herself.
"Steffi has her own opinions, and I have my opinions also, but I don't think they are supposed to be public," Seles said. "Women's tennis is a small group, and I think the top players should stick together, not make accusations."
Petr Korda got even with Andre Agassi, eliminating the third seed from the $1.2 million tournament with a straight-set victory.
Korda lost to Agassi last week in the final of the Sovran Bank Classic at Washington. But the lanky Czechoslovak defeated Agassi, 7-6 (7-3), 6-2, in the third round, using his explosive forehand.
Agassi becomes the highest seed eliminated from the tournament so far. Fourth seed Michael Chang and fifth seed Pete Sampras were upset Tuesday.
Seventh seed John McEnroe became the ninth seeded player to advance to the third round, making quick work of Jimmy Arias with a 6-1, 6-2 victory last night.
"Considering how windy it was, it was hard to gauge how well I played," said McEnroe, a two-time winner at the Canadian Open. "I was playing quickly because I felt things were going my way."
Top seed Ivan Lendl and second seed Jim Courier are still alive, although Lendl was extended to a third set yesterday.
Lendl dropped the first set to Gilad Bloom of Israel, but rebounded for a 4-6, 6-4, 6-4 victory. Courier, who won the French Open, defeated MaliVai Washington, 7-5, 6-3, in a second-round match.
Lendl, who has won this tournament six times, had not played since Wimbledon in late June.
"I had a terrible time getting any rhythm," Lendl said.
The world's third-ranked player also had trouble with the winds.
"It isn't a problem when it's blowing up or down the court. Today, it was swirling and gusting," he said.
In a minor upset, Jim Grabb eliminated ninth seed Richey Reneberg, 6-7 (7-3), 6-2, 7-5.
