Andy Murray has pledged to give £50 to children's charity Unicef every time he hits an ace for the rest of the season in a bid to help the refugee crisis.
Murray, 28, said that he was moved to act by coverage of people travelling to claim asylum in Europe.
"Having seen the images broadcast on the news I felt I had to do something to help," he said.
Murray's sponsor Standard Life, along with the Lawn Tennis Association and ATP, will each match his donation.
