#3 Jimmy Connors (5 titles)
Jimmy Connors won the first of his five titles at the US Open in 1974 by dropping only two games against 1970 champion Ken Rosewall of Australia. It was the last edition of the US Open on grass as the tournament transitioned to clay the next season.
After being thwarted by Orantes in the 1975 final, which was also the first US Open to be played on clay, Connors won his second title at the tournament by beating Swede Bjorn Borg in four sets in the 1976 title match.
Guillermo Vilas beat the defending champion Connors in the last US Open to be played on clay in 1977, before the tournament moved to hardcourt and to its present venue of Flushing Meadows.
Connors returned to the US Open final for a fifth consecutive year in 1978, where he beat Borg in the first US Open Championships to be played on hardcourt. The win made Connors the only player to triumph at the US Open on all three surfaces.
The American beat Lendl in successive US Open finals in 1982 and 1983 for his fourth and fifth titles respectively at the tournament.
