Novak Djokovic made a charitable donation and opened tennis courts at the School of Friendship on Tara Mountain in his homeland of Serbia.

“It is important to see children laughing and having fun, enjoying in this wonderful center,” said the World No. 2. “This is a great thing and it is not just my wish, but also the wish of Serbia and all of us standing here.”

Djokovic spent time with kids, handing out t-shirts and taking photos with them.

He was scheduled to play in the Los Angeles tennis event but withdrew. His next event will be the Toronto Rogers Cup next month.
