Beginning at 9 a.m. Sunday, NBC-TV (WRC-TV-4) will bring to the United States what it proudly calls "Breakfast in Paris."

Before the day is done, it might also be bringing lunch and dinner if the finalists play their characteristic styles.

Like most everyone here, the network expected Sunday's men's final in the French Open to be a rematch of last year's classic five-set final between Ivan Lendl and John McEnroe, won by Lendl.

Lendl did his part, cruising into the final without the loss of a set, including a crushing straight-set defeat of Jimmy Connors in Friday's semifinals. But McEnroe lost in straight sets to Swede Mats Wilander in Friday's other semifinal. Wilander, 20, won here in 1982, was runner-up in 1983 and is playing his best tennis of the year.

"I seem to play better in the big tournaments," he said. "I really have trouble concentrating in other tournaments because I sometimes get bored with tennis. But for the big tournaments I seem to play well."

In fact, Wilander has won three Grand Slam titles, to Lendl's one, having won the Australian Open the last two years. Lendl is 7-5 against Wilander lifetime and beat him, 6-1, 6-1, on clay two weeks ago in Dusseldorf, West Germany.

"But he is playing much better now," Lendl said. "If he wasn't, he certainly would not still be in the tournament."

When he won here, Wilander was strictly a back court player. Now, he attacks more and says he will try to get to the net against Lendl. Connors found out Friday that it's tough to come in on Lendl here. Lendl still is most comfortable at the base line. That means the match is likely to be full of long rallies.

"If it takes me seven hours to win, I'm prepared to stay out there for that long," Lendl said. "That's what winning a Grand Slam tournament is all about."
