Re: Fed Playing Doubles in Dubai with Allegro!!!!
It isn't a surprise at all, since whenever Federer is playing doubles, it is with his old buddy Allegro. He played last year with Yves Allgro in Dubai too.
It has become pretty rare though, and the success hasn't been too great:
Dubai: 6-1 6-7(4) 6-10 vs Knowles/Nestor
Indian Wells: 6-7(4) 5-7 vs Gasquet/Grosjean
Monte Carlo: 6-3 3-6 10-6 vs Levinsky/Safin
6-1 6-2 vs Huss/Vizner
4-6 5-7 vs Bhupathi/Stepanek
Hamburg: 6-3 6-4 vs Ferrer/Hrbaty
4-6 2-6 vs Paes/Zimonjic
Halle: 6-3 5-7 6-3 vs Damm/pavel
w.o. vs Canas/Nalbandian
7-5 RET vs Bhupathi/Woodbridge
7-5 6-7(6) 6-3 vs J. Johansson/Safin (Title!)
Cincinnati: 7-6(5) 1-6 6-7(2) vs Friedl/Pavel
The two have also won the doubles in the two Davis Cup matches Federer played in 2005 and 2006 against GBR and SCG, respectively.
Anyway, I think the reason Federer plays the doubles from time to time is because he likes to play with Allegro and also to get some extra match practice in after long breaks, e.g. in Dubai after chilling 1,5 month post Aussie Open.
