#2 More matches played and match wins than any other player
Connors had a spectacularly long tennis career. He became the oldest ever to play in the Open Era to feature in a Grand Slam semi-final. He achieved this feat at the US Open of 1991. On his 39th birthday, he defeated 24-year old Aaron Krickstein in 4 hours and 41 minutes despite trailing by 2-5 in the final set.
He described his journey to the semi-finals as 'the best 11 days of his life'. The winner of eight Grand Slam titles and three ATP Finals trophies, Connors won a total of 1256 matches out of 1535 appearances (both all-time records). His win percentage of 81.96% is among the highest in the Open Era.
Connors continued to play tennis against much younger opponents even at the age of 41. However, post-1993, his appearances were few and far in between. He finally retired in 1996 at the age of 44.
