John McEnroe, Wimbledon 1981: Four Words, One Point Penalty and the Title Anyway
The first-round outburst that became the most quoted line in tennis came two weeks before McEnroe ended Björn Borg's five-year reign.
Monday, 22 June 1981, Wimbledon's first round. John McEnroe was on Centre Court against Tom Gullikson. A ball was called out. McEnroe disagreed.
"You cannot be serious," he told the umpire, Edward James. Few sentences spoken on a tennis court have been quoted more.
What happened, in order
Tennis Majors reconstructs the sequence like this:
- McEnroe protests the call with the words that became his catchphrase. He
receives a warning.
- In the next game he calls the umpire "the absolute pits of the world."
That costs him a point penalty.
- He then calls the official an "incompetent fool" and asks for the
referee.
He won the match 7–6, 7–5, 6–3 and was fined $1,500 for his conduct in it. Gullikson's verdict afterwards was short: "It has no place. Everyone's afraid of these guys."
James, years later, had an even shorter one. "It was the first time I'd umpired him and also the last."
Two weeks later
The outburst is what people remember. The tournament is what it led to. McEnroe went through the draw and met Borg in the final. Borg had won the title five years in a row and had beaten McEnroe in the 1980 final, the match the site tells in full on its classic-matches page. This time McEnroe won 4–6, 7–6, 7–6, 6–4. It was the first of his three Wimbledon titles.
The All England Club's board then decided not to make him an honorary member. McEnroe answered by not attending the Champions' Dinner.
What was in the hand
McEnroe in 1981 was still a wood player. The source the site already uses for his wood era, The Racket Surgery, names the Dunlop Maxply Fort and a reported tension in the low-to-mid 50s of pounds. That is a range for the period, not a stringer's sheet from that fortnight, and it is shown here as such.
It matters to the story because of the contrast with the man he beat. Borg strung his wood above 80 pounds, as the site's Borg story records. McEnroe's much looser stringbed held the ball longer on the strings, which is what a player who wins with touch at the net wants. In 1981 the touch won.
The line that outlived the match
The phrase took on a life of its own. McEnroe used it as the title of his autobiography, You Cannot Be Serious, published in 2002.
For a club player there is a second, less glamorous lesson in 1981. A point penalty in the first round did not stop McEnroe from winning the tournament. It also made him the champion the club would not honour. Both of those things happened in the same fortnight.
What is not on this page
There is no recording here of which line call started it, on which point or at what score. The sources we read do not record those details, so we have left them out rather than guess.
