With Philipp reaching his 4th quarterfinal appearance at a Masters Series event, he sets up a chance to play Nadal.
Neither of them are playing their best but this should be an intriguing match. Nadal has yet to beat Kohlschreiber in straight sets outside of clay, so I think we should see a 3 setter because we all know how Philipp loves to tease us and piss the top players off. Philipp has the ability to beat Nadal, so it isn't impossible, but it will be a big mountain to climb. Early this year, Philipp nearly took Nadal to 5 at the Australian Open as well, so cross your fingers for an entertaining matchup.
