In my opinion this match can be very close, three sets are very possible here. The best option for this match is Over 22.5 with nice odds to play in Pinnacle Sports. I must try it.
Lukas Rosol played two times against Bjorn Phau and both matches for sure are very close..
Lukas Rosol is in hot form in this moment, at Wimbledon made one of the biggest suprise in tennis history. Won against Rafael Nadal in third round of Grand Slam.
Of course Rosol is favourite here, but Phau is home player and always is dangerous when his serve working good.
I see close match, the most possible scenario - three sets for Lukas.
