Third-seeded Ivan Lendl hit 12 aces in beating Scott Davis, 7-6 (7-0), 6-2, and Stefan Edberg struggled to the end to stop Jakob Hlasek, 6-4, 3-6, 7-6 (8-6), yesterday on artificial courts at Tokyo Metropolitan Gymnasium to set up a semifinal match in the Seiko Super tournament.
Second-seeded Boris Becker defeated Andrei Cherkasov, 6-4, 6-4, and unseeded Richey Reneberg beat Thomas Hogstedt, 6-3, 6-2, to set the other semifinal.
Edberg and Hlasek each broke serve once, Edberg in the seventh game of the first set and Hlasek in the second game of the second set. Despite 69 unforced errors, 58 percent on first serves and six double faults, Edberg was not displeased. "It was a very good match," he said. "I didn't play my best but I thought I played well enough."
Lendl broke Davis in the first game, but Davis broke back in the sixth game to set up the first-set tiebreaker, which Lendl won, 7-0.
"I served very well today," said Lendl (80 percent of first serves). "I was broken because of the surface. . . . It doesn't matter how well I play, I still don't like this fast surface."
