Connors–McEnroe rivalry

The Connors–McEnroe rivalry was a tennis rivalry between Jimmy Connors and John McEnroe, who played 34 times between 1977 and 1991. Their head-to-head was 20–14, favoring McEnroe.

Connors and McEnroe played again in the late 1990s and the early 2000s on the senior tour. With regard to their matches, Connors has stated, "Something like that never goes away, especially between Mac and myself...To have carried on this rivalry for so many years, and for you still to be talking about it, must mean that we made our mark somewhere." This rivalry is said to have been one of the most contentious and embittered in all of tennis history.
