1990 Australian Open – Men's Singles


First-seeded Ivan Lendl successfully defended his title by defeating Stefan Edberg in the final 4–6, 7–6, 5–2 ret., to win the Men's Singles tennis title at the 1990 Australian Open. Edberg was forced to retire during the third set of the final because of a torn stomach muscle. The Swede's retirement marked the first time since the 1911 Wimbledon Championships that a male player withdrew during the singles' title match of a Grand Slam tournament.
Former world No. 1 John McEnroe created controversy after he was disqualified from his fourth round match for unsportsmanlike conduct. He received a warning for intimidating a linesperson, a point penalty after smashing his racket, and was defaulted for arguing with and abusing the umpire, supervisor and tournament referee.
