Totally agree, spacey. Stefanos Tsitsipas deserves to go all the way. It's good to see a young 20 year take on the greats. He seems to be a very likeable character as well. I hope he wins it. With the huge Greek population in Melbourne, he'll always draw the crowd support when he plays here.
He seemed to stop Federer from playing his usual game. Most times when Fed put his usual winning shots right out on the line, Tsitsipas was banging them straight back. Had Roger scratching his head I think.
