Thiem with a hybrid?


If you see some pics from the US Open this year, it looks like he has gut or some white/natural string in the crosses. Weirdly, I only saw this in the final. Other matches I see what seems to be a full bed of RPM Power.
Closeup pics of his setup at the Open look like black (gut?) in mains and the usual champagne colored RPM Power in crosses. Can anyone confirm?


This is a picture from the final. He was using full bed of RPM Power. You can clearly see it is full bed (mains and crosses).
