Ok, this is very statistical thing but I guess it would be interesting for some members. In Internet circulates the information that Guillermo Vilas has had the longest streak of winning matches - 46.
It isn't true.
In 1978 Bjorn Borg won 49
conscutive matches. I saw a couple of times that Borg in 1978 won 43 matches in a row. Initially I thought this stats doesn't include Davis Cup matches therefore Borg won 43, I was wrong. When Canas defeated Federer in Indian Wells there was announced that Canas finished Federer's 41 winning matches streak. Those 41 matches included 2 wins in Davis Cup against Serbian players. The same thing with McEnroe's 42 consecutive wins in 1984 (2 wins over Romanian players in Davis Cup).
So, the most popular version of this stats is:
1) Vilas - 46 (1977)
2) Lendl - 44 (1981-82)
3) Borg - 43 (1978)
4) McEnroe - 42 (1984)
5) Federer - 41 (2006-07)
The inaccuracy is probably connected with the fact that atptennis.com site contains some errors, in this case doesn't include Borg's Davis Cup matches from 1978.
Another interesting thing: how to count some old tournaments? For instance ATP tells us that Borg won 63 tournaments. Some of them were freaky ones, like Pepsi Grand Slam
(only 4 players draw: 3 matches there; 2 SF's & Final) or WCT Invitational
were 6 players participated, they all played against each other, and the two best, later played a final the best of five :retard: If we count these tournaments, Borg in years 1979-1980 had second longest streak of 48
