P/P are 9-4 on ATP level. I don't think they can hold this level, but hopefully the top 8 are possible next year. Philipp has already won 950 points in doubles since the grass season, so he has a real good chance to reach the top 20 next year in the individual doubles ranking.
He should realize that Basel has a stronger list, so play St.P. St. Petersburg, Aachen and Bratislava should have livestream.
