MONTREAL, AUG. 14 -- No. 4 seed Jimmy Connors broke serve in the eighth game of the third set today to key his first victory over John McEnroe in their last 11 meetings, a 6-3, 3-6, 6-3 quarterfinal decision in the $375,000 Player's International.

In other quarterfinal matches, No. 1 Ivan Lendl defeated No. 10 Slobodan Zivojinovic, 6-3, 7-5.

No. 2 Stefan Edberg beat No. 8 Kevin Curren, 7-6 (7-5), 7-5, by rallying from a 1-5 deficit in the second set with three consecutive service breaks. No. 3 Boris Becker downed Peter Lundgren, ranked No. 112 in the world, 1-6, 6-2, 6-1.

Connors will meet Lendl in the semifinals Saturday and Becker will play Edberg.

"Anytime I play McEnroe, it brings out the best in both of us," Connors said. "It was pretty exciting. I got a lot of my first serves in tonight. I did everything well. That's what I have to do to beat McEnroe."

In his match against Lendl, Zivojinovic fought back from love-40 in the last game of the second set to tie the score, only to lose it on a double fault on match point after his first serve was ruled out.

Zivojinovic protested the call vehemently, then double-faulted on his next serve to lose the set and match.

Lendl acknowledged that some poor calls were made against his opponent.

"He got two bad calls on the third match point," Lendl said. "I got lucky breaks, but he played badly. He missed first serves."

Lendl's match, the first of the day, was postponed for four hours because of rain and was interrupted for another 1 1/2 hours by rain after the first set.

Becker had two aces and six double faults in his match. Edberg collected three aces and one double fault against Curren.
