Andy Murray claims 500th ATP Tour win after beating Kevin Anderson in Miami

Andy Murray became the 46<sup>th player to reach 500 ATP Tour victories after defeating South Africa's Kevin Anderson to reach the Miami Open quarter-finals.

The British No.1 prevailed 6-4 3-6 6-3 in a gruelling encounter to set up a last eight clash with Dominic Thiem, who overcame Adrian Mannarino in three sets.

Murray joins the likes of Roger Federer, Rafael Nadal and Novak Djokovic as one of nine currently active players to reach the 500 mark and the No.3 seed admits he has a further target in mind before retiring.

"It means a lot," he told Sky Sports. "There are not a huge amount of people who have been able to get to 500 so it's very nice to have done that. To have done it in Miami was quite fitting because I've done a lot of hard yards on this court.

"There is a certain number I would like to get to before I finish playing and hopefully my body can hold up and give me an opportunity to get there.

"I expect a tough match [against Thiem] and he has his best year on tour last year and made some big improvements. He likes the conditions here. I practised with him the other day and I practise with him quiet a lot."

Victory over Mannarino in Indian Wells last week saw Murray eclipse Tim Henman as the British singles player with the most tour wins but will now refocus his efforts on claiming his first title of 2015 in Miami.
