Cameron Norrie admits to nerves during his three-set win over a struggling Andy Murray at the Cincinnati Open

Cameron Norrie said that his positive attitude helped him seal his first-ever win over British compatriot Andy Murray at the Cincinnati Open. Norrie's 3-6 6-3 6-4 win in 2h37 was not one of his better performances, with the 35-year-old Murray in the ascendancy for much of the match. Ad But Norrie never wavered mentally, and he admitted afterwards that was the key as he ground down Murray, who ended the match unable to walk due to cramps, a problem that has been his bete noire during the US hard-court season so far, and that saw him helped off the court at the finish.

I was looking really slow and not moving well but I managed to do that better and better as the match went on.

«Maybe it was a little bit to do with nerves. When you're feeling tight the feet are the first thing you struggle to work. That's how it rolls with tennis, hopefully I can keep improving.
