I finally found some broadcasting information of the WTA Tour for the comming week.
Since Eurosport has more interest in Football, the German channels ZDF and ARD will broadcast most of the Tour.
Here's the schedule for the comming week:
15.00 CET - ZDF, Semi-Final
14.45 CET - ZDF, Final
23.45 CET - Eurosport, Final
13.00 CET - Eurosport, Final (replay)
14.00 CET - ZDF, German Open Berlin
14.05 CET - ARD, German Open Berlin
14.15 CET - ARD, German Open, Quarter Finals Singles
Enjoy the games!
