Tennis Roundup : Chang, 15, Advances to Semifinals

Fifteen-year-old Michael Chang became the youngest player to reach the semifinals of a Nabisco Grand Prix event Friday by defeating Mexico’s Jorge Lozano, 6-4, 6-1, in the $303,400 WCT tournament at Scottsdale, Ariz.

In other matches, David Pate eliminated Kevin Curren, 6-2, 7-6; Eliot Teltscher beat Sweden’s Peter Lundgren, 3-6, 6-3, 6-4, and Brad Gilbert defeated Johan Kriek, 6-2, 6-4.

Chang plays Gilbert, and Tate meets Teltscher today.

Chang, an unseeded amateur, needed only 65 minutes to defeat Lozano, ranked 129th in the world.

“I really didn’t know anything about him until I got on the court,” said Chang, who just entered Valencia High School in Placentia. “I felt comfortable as the match got going, and he didn’t put pressure on me. I think he got nervous because he made a lot of unforced errors.”

Paul Annacone eliminated Sweden’s Stefan Edberg, 6-2, 6-3, from the $500,000 AT&T; Challenge at Atlanta.

The victory gave Annacone a spot in today’s semifinals against top-ranked Ivan Lendl.

John McEnroe will meet Jimmy Connors in the other semifinal.

McEnroe defeated Sweden’s Mikael Pernfors, 6-2, 6-3, while Connors beat Ulf Stenlund, 6-0, 6-1. Earlier, Lendl downed Miloslav Mecir, 6-0, 6-4.

Australia’s John Frawley upset Wimbledon champion Pat Cash, also of Australia, 6-4, 6-3, to advance to the semifinals of the $150,000 Queensland Open at Brisbane, Australia. It was the 28th consecutive victory for Frawley.

In another match, New Zealand’s Kelly Evernden beat India’s Ramesh Krishnan, 7-6, 6-1.

At Basel, Switzerland, France’s Yannick Noah breezed past Austrian Horst Skoff, 6-2, 6-4, to advance to the semifinals of the $239,000 Swiss Indoor championship.
