#2 Win 40 consecutive matches at 2 Grand Slam tournaments
While William Lernad, Richard Sears and Bill Tilden each won a record 7 US Open titles, the trio's triumphs came at a time when Grand Slam tennis was open to amateur players only.
In the Open Era (1968 onwards), only 3 players have lifted the US Open title on 5 occasions - Jimmy Connors, Pete Sampras and Roger Federer. But unlike his two American counterparts, Federer's 5 triumphs in New York came in successive years.
Only 2 other players - John McEnroe (1979-81) and Ivan Lendl (1985-87) - have won 3 consecutive US Open titles in the Open Era.
Federer's 40-match win streak at Flushing Meadows (2004 to 2009), a streak that he repeated at Wimbledon (2003 to 2008), is unheard of. Bjorn Borg had also won 40 consecutive matches at Wimbledon (1976-81), but the Swede never won a US Open title.
It is thus safe to surmise that Federer's 40-match win streaks at 2 different Grand Slam tournaments is unlikely to be surpassed by anyone in a long long time.
