Greek Stefanos Tsitsipas commented on his defeat by Briton Cameron Norrie in the Hopman Cup. “I could not get used to the opponent and the courts. Cameron played great, but I was uncomfortable. I can not even explain why. Perhaps the whole thing in the weather. Local heat is different from the one that was in Dubai, where I trained. It seems to me that I get tired very quickly. This is sad because I did a good job in the offseason, “the official website of the competition quoted Tsitsipas as saying.
