it wasnt tight today, gulbis was controlling last two sets
Anyway Voo de Mar gave an even more impressive streak : that he lost last 8 matches, I think, where at 5-5 in third final set.
Anyway it's like that : Federer likes records and streaks
He has won 22 or 23 finals in a row, I don't remember, played 22 semifinals in grands slams in a row, still holds the record for percentage of tiebreaks won including a tremendous one for tiebreaks won in grand slam final (and also great figures for tiebreaks played at 6-6 as Voo de Mar mentioned once).
He even has the record of cookie plates for being runner-up of every grand slam (not only winner)
He also likes wasting some records which are nearly given from time to time as he may do for the record number of weeks at number 1 and as he did against Canas in the past for Vilas's record streak of matches won, as he also may do for Agassi's record in MS1000 tournaments
Also for tiebreaks in grand slam finals, he won 80% of them but once he lost one, he lost two of them (against Del Potro in the US Open)
the same for the streak of tiebreaks won : he lost it against Djokovic and lost two tiebreaks to lose Montreal that day ; once he lost to Canas to end his winning streak, he lost twice to the same one ... it all goes by streaks even when the previous one ends
