Kevin Anderson has spoken out after ending defending champion Roger Federers Wimbledon campaign.
Federer, who was chasing his ninth triumph at the All England Club, took the opening two sets in fine style.
He then had a match point saved in the third, before South Africas Anderson levelled the match at 2-2.
A gruelling final set ended with Anderson winning 13-10 as he booked his place in the semi-finals with a fantastic victory.
At 2-0 down I tried my best to keep fighting and was able to scrape through and by the end I thought I did a great job, he told BBC moments after the win.
Beating Roger Federer at Wimbledon will be one I remember, especially in such a close match.
I just kept on telling myself I had to keep believing and saying today was going to be my day, you need that against someone like Roger.
If you go out with doubts – like maybe I did in the first set – its not going to go your way.
As the match went on, I gave it my all and obviously Im very ecstatic.
Anderson, who reached the US Open final last year, will face John Isner or Milos Raonic in Fridays semi-final.
I have to recover now and focus on my match on Friday, he added. Theres more tennis to be played.
I need to take this in – it was a special match – but now its time to recover and hopefully play two more matches.
