Rafael Nadal defeats Matteo Berrettini and advances to the finals of the US Open 2019. The world No. 2 said: "what he's doing, he's in semifinals. He was in semifinals of the US Open. He had a great run on grass, too.
I think he's 23. Has plenty of time to keep doing things. He has a big serve, big forehand. No, he is strong. He has a great potential to become a player who fights for the big things for the next eight years."
