Ivan Lendl, the world's No. 1 tennis player, and Boris Becker, ranked No. 4, won first-round matches Wednesday in the $375,000 Seiko tournament at Tokyo.
Lendl trounced Jonathan Canter, 6-1, 6-4, while Becker struggled to a 7-5, 7-5 victory over Jim Grabb, ranked 78th in the world.
Afterward, Lendl told reporters: "I am in good condition now. After the U.S. Open in September I lost speed but regained it last Friday and Saturday when I won a tournament in Sydney."
In other first-round matches, Eric Jelen of West Germany rallied to beat Ulf Stenlund of Sweden, 2-6, 7-5, 6-2, and West Germany's Damir Keretic defeated compatriot Wolfgang Popp, 6-1, 6-1.
