“I had actually never been on Centre Court before,” said Brown.
“They asked me before the match if I wanted to go on the court. I didn’t know what was going to happen, so I just said I’ll just go on when I play.
“I thought I would freak out a little bit but I don’t know if it was the match in Halle, it felt very familiar. It wasn’t obviously that big of a court but being on grass, being with him on the court and having won the last match it made me feel more comfortable.”
He added: “It’s easy for me to play my game against someone like him because I have nothing to lose.”
Nadal had the luxury of the first break for a 3-1 advantage in the opening set which was quickly cancelled out by Brown in the fifth game.
