I ended up in a rain delay…followed by going indoors to play my match in the Tennis Halle. The surface is a soft carpet. This one wasn’t too slippery, but was slow for a carpet, spongy almost. The Halle had a green carpet…I meant to take a photo, and the outside wall, like many Halles in Germany and Austria had a lot of light coming in. By the time we finished (I won 60 63), the sun had come out and all the clay courts were pretty dry. Tomorrow’s forecast looks fine.
