TOKYO -- Top seeds Ivan Lendl and Stefan Edberg encountered trouble in their third-round matches Thursday before advancing to the quarterfinals of the $1 million Japan Open.
Lendl, the No. 1 seed, overcame qualifier Joseph Russell, 7-6 (8-6), 6-2, while Edberg staved off Alex Antonitsch, 6-2, 6-7 (2-7), 6-1.
'The wind always gets up in the afternoon,' Edberg said. 'But I didn't expect it today. He played some good shots and he made some lucky ones in the tie-breaker, but I knew when I broke him in the final set that would be it.'
Also advancing to the quarterfinals were Americans Brad Gilbert, Aaron Krickstei, Michael Chang and Jim Grabb, Australian No. 6 Wally Masur and No. 10 Amos Mansdorf of Israel.
Gilbert, seeded third, called his match with West Germany's Alexander Mronz 'a struggle' but he emerged with a 4-6, 7-5, 6-1 triumph.
'I had a hard time finding my rhythm today,' Gilbert said. 'I was fortunate to get the victory. He was up a break 4-2 in the second set, but I put together a decent game to get to 4-3. I wasn't playing well, but I played better and I forced him to make more shots.'
Krickstein, the fourth seed, had an easier time in disposing of Canadian Grant Connell, 6-3, 6-2, but Chang, seeded No. 5, had problems with West Germany's Patrik Kuhnen before winning, 7-5, 6-2.
'Patrik plays mostly serve-and-volley, but he can play from the back as well,' Chang said. 'In a way, that makes him more dangerous because he has something he can fall back on if something's not working.'
Kuhnen played serve-and-volley when he could, but Chang forced him to the baseline by consistenly passing his opponent. Chang frustrated Kuhnen at the net, passing cross-court with his backhand when Kuhnen expected him to go down the sideline.
Kuhnen squandered a 2-0 lead in the first set when Chang broke serve and held to tie the score. Chang finally broke Kuhnen again at 5-5, then held to win the set.
Kuhnen managed to battle back from a 2-0 deficit in the second set, but Chang took control from there.
'I played better today than I did on Tuesday,' Chang said. 'It wasn't as windy and I got to a lot more balls today than I did in my first match.'
Chang plays Krickstein in the quarterfinals while Lendl faces Mansdorf and Edberg plays Grabb, the seventh seed. Gilbert will meet the sixth-seeded Masur, a 6-2, 7-6 (7-5) winner over Patrick McEnroe.
Mansdorf, seeded 10th, defeated No. 8 Scott Davis, 7-6 (7-5) 6-7 (4-7), 6-2,and Grabb topped No. 9 Mark Kratzmann, 6-4, 6-2.
