John McEnroe capped a tumultuous two weeks at Wimbledon today by ending Bjorn Borg's five-year reign and 41-match winning streak here with a four-set victory in the singles final.
On the day that the tournament committee of the All England Club recommended a $10,000 fine for his stormy semifinal match against Rod Frawley, which could lead to a suspension, McEnroe showed that he could control his serve and temper when it counted, even when close calls went against him in stressful situations.
The scores in the 3-hour-22-minute match were 4-6, 7-6, 7-6, 6-4. McEnroe, the 22-year-old New Yorker, dominated the two tiebreakers, 7-1 and 7-4, with his deep, sharply-angled southpaw serve. Of the last eight matches between the two, 12 of the 27 sets have been settled by tiebreakers.
''This is a triumph of McEnroe over Borg,'' the winner said, when asked if he had conquered his temperament with today's performance. ''Anytime I can beat him it's fine with me.''
Frew McMillan of South Africa and Betty Stove of the Netherlands saved the tournament from the first American sweep since 1939 by beating John and Tracy Austin, 4-6, 7-6, 6-3, in the mixed-doubles final.
Yesterday Chris Evert Lloyd won the women's singles final and McEnroe and Peter Fleming the men's doubles. Today Pam Shriver and Martina Navratilova took the women's doubles, 6-3, 7-6, from Kathy Jordan and Anne Smith, and Matt Anger of Pleasanton, Calif., and Zina Garrison, a black from Houston, won the junior titles.
McEnroe was jubilant and relieved when his forehand volley landed deep in a corner for a winner on his second match point. He started to drop to his knees, then, recalling Borg's traditional prayerful ritual on the turf after his five victories, decided to stay on his feet.
This final lacked the spontaneity and drama of last year's fiveset classic, which Borg won, 8-6, in the fifth set. But with $22 center-court seats scalped for as much as $1,000 and a capacity crowd filled with European royalty, celebrities and standees who had lined up outside the grounds in sleeping bags for more than a week, the interest was unsurpassed.
Even before the first serve, spectators shouted the names of the players and chanted ''Hooray!'' and ''Boo!'' as if they were in a soccer stadium and not in a setting laden with tradition. But then the two weeks, with record crowds, large fines against players and enraged fans throwing cushions on the center court to protest a doubles match curtailed by darkness, had brought Wimbledon further than ever from its traditional roots.
McEnroe had sensed the occasion, even as he struggled with almost daily diversions, ranging from the status of his first serve to confrontations with British newsmen and erroneous reports that he had been stopped for speeding. ''It's got to happen sooner or later,'' he said yesterday, when asked if the top-seeded Borg could be beaten here. The last man to have beaten Borg at Wimbledon was Arthur Ashe in the fourth round in 1975. Clay Tennis on Grass
McEnroe had watched parts of Borg's five-set comeback against Jimmy Connors in Thursday's semifinal. It was clay-court tennis on grass, McEnroe reasoned, and he would not play like Connors. ''I'm going to hit the ball softer, dink, chip, come in,'' he said.
Yesterday he tried to get the ''feel'' of his serve during the doubles final, which he and his partner, Fleming, took in straight sets from Bob Lutz and Stan Smith. Before today's match, he practiced shadow-serving and went over notes he had written about his serve and stored in his racquet cover: keep the head up, throw the toss more to the left, try to stay ahead.
Borg, who had been blitzed by Connors in the first two sets, struck first, breaking McEnroe from deuce in the fifth game and then holding for the set from 15-40 and 4 break points.
''He controlled the first set and a half,'' McEnroe said. The Big Serve
If McEnroe had not served well, Borg probably would have received the $43,000 first prize of the $650,000 purse and the winner's trophy from the Duke and Duchess of Kent. Even with his 10 double faults, McEnroe's first serve emerged as the dominant weapon. It saved him 13 of 15 break points and helped him to control the tempo. Much of McEnroe's game revolves around his first serve, particularly against a rival like Borg, whose penetrating ground strokes can pick apart most serve-and-volley stylists. But McEnroe forced him so wide off the court with his first serve that the Swede had no leverage to counter McEnroe's diverse volleys - dinks, drops and drives.
''When you hit in the first serve, you gain confidence, especially John,'' said Borg, who acknowledged that returning serve from his customary position far behind the baseline and especially from a wide position in the ad court, had ''left the whole court open.''
The extent to which McEnroe's first serve dominated play was reflected in the statistics: he won 82 of 104 points played on his first serve, a staggering 79 percent, but only 32 of 63 points played on his second. His first-serve percentage was 62, which is respectable. Borg was under 50 until the fifth game of the third set, and finished at only 55, despite 10 aces.
Nowhere was the difference more noticeable than in the second-set tiebreaker. McEnroe got in all four of his first serves, and won all 4 points. In both tiebreakers, he got in a total of nine of 10 first balls. Borg, who had said that ''you can't play scared on your serve in a tiebreaker,'' faulted three of his four first serves and went out quietly. 3d Set Was Important
''The match was very close,'' Borg said. ''It was important for me to win the third set. When I had 4 set points, on the important points, when he had to win them, he hit his first serve in.''
The key game of the match was the ninth in the third set, with McEnroe down by 4-5 and serving at 15-30, after Borg had squandered a 4-1 lead. Attacking behind his serve, McEnroe punched a forehand volley that the base linesman signaled good. Bob Jenkins, the umpire, who had officiated at two previous McEnroe matches, overruled the linesman. ''The ball was out,'' Jenkins announced.
Thinking the shot was good, McEnroe paused in the backcourt. Spectators waited, expecting a tantrum or confrontation. McEnroe balanced the white ball on the strings of his racquet, still seemingly uncertain what he wanted to do.
''The ball was clearly out,'' Borg said later. ''Those things happen.'' Instead of 30-all, McEnroe was at 15-40, double set point. A voice from the stands cried out, ''Play on, John!'' McEnroe looked in the direction of the caller, but said nothing.
Finally he served, attacked and won the point with an overhead. Thirty-40. A service winner to the forehand. Deuce. He survived 2 more set points and finally held on the sixth deuce.
''Maybe it was good for him that he controlled himself,'' Borg said. Borg Leads in Tiebreaker
Borg led in the third-set tiebreaker only once, 3-2. But McEnroe volleyed behind his next two serves for 4-3, then swept Borg's two serves with a looping forehand cross-court pass and a backhand pass down in the line.
McEnroe holds an edge on Borg in their tiebreakers. ''If his big serve is working in tiebreakers,'' said Borg, who had won his four previous tiebreakers in the tournament, ''it's a big advantage.''
McEnroe was determined not to let Borg reach a fifth set. Last year he ''let him off the hook'' in the second set. Close the door and don't let him back in, McEnroe told himself, saving 2 break points from 15-40 in the third game of the fourth set and skidding a service winner to the backhand at 15-30 in the fifth game.
Borg struggled from 15-40 and held to 4-all. But the pressure of maintaining the streak and harnessing his serve appeared to take its toll at 4-5. At 30-15, he came in behind his serve, only to stroke a backhand volley long. McEnroe attacked a second serve and reached his first match point when Borg netted a two-handed backhand.
''If I held to 5-all, I felt I could break him,'' Borg said. He shunned the baseline to serve and volley, and saved the first match point with a deep backhand volley that McEnroe could not counter.
But Borg's serve, perhaps dulled from Thursday's tiring two-set comeback against Connors, could not hold up. McEnroe moved in on the second serve, pressured Borg's backhand and won the point with an overhead. Another second serve brought the American in for the clinching volley.
