I agree that there will be a Rogie-Raonic QF showdown on Friday 6/15, however I expect Rogie to win that match. Raonic a career 3-2 on grass with 0 titles vs. Rogie a career 102-15 on grass with 11 titles (in 26 tournaments played). The finals will be Rogie vs. the winner of the Rafa-Berdych SF.
Well if you are going to put it like that vs. the GOAT, which isn't even worth comparing cause we all know that.
However to be fair Milos is a young guy and plays about 2 grass tourneys a year, so it's hardly a surprise.
