It's one of the reasons why Connors is vastly underrated in the GOAT discussions. In 35 consecutive slams entered, he fell short of the QF only once.
Federer has an amazing record of 33/33 slams, but, still has a little ways to go to break Connor's record. Two more slam QFs will do it.
Kevin Curren has the honor of being the only man in 35 slams entered to defeat Jimmy Connors before the QF. On court 2 the 'Graveyard of champions'.
If I am correct, Roger have 34 of the last 35 only a loss in Roland Garros in 2004
