Paul Annacone upset Sweden's Stefan Edberg, 6-2, 6-3, Friday, eliminating the world's No. 2-ranked tennis player from the $500,000 AT&T Challenge exhibition tournament at Atlanta.
The victory lifted Annacone's record in the round-robin phase of the event to 2-1, giving him a spot in today's semifinals.
"I felt that mentally I was more eager to win the match than Stefan," said Annacone, who is ranked No. 41.
Top-ranked Ivan Lendl and Jimmy Connors are also in the semifinals, and John McEnroe went for the last spot in a match against Sweden's Mikael Pernfors. Connors was to play Ulf Stenlund later, but his 2-0 mark already assured him of a berth.
Lendl beat Miloslav Mecir, 6-0, 6-4, to give him a round-robin record of 3-0.
Edberg finished with a 1-2 record.
