Australia's Broderick Dyke, ranked 109th in the world, stunned West Germany's Boris Becker, 6-3, 6-3, Wednesday in the first round of the $315,000 Belgian Indoor Championships at Brussels.
Dyke needed only 80 minutes to beat the reigning Wimbledon champion.
"I was surprised by the number of errors a player like Becker could make," Dyke said.
Becker was flabbergasted.
"I played badly, I don't understand what happened. I had no timing and was unable to accelerate my game during the match."
At New York, second-seeded Chris Evert Lloyd and sixth-seeded Pam Shriver took different routes but moved easily into the quarterfinals of the $500,000 Virginia Slims Championships.
