Francis Tiafoe, Next Big American Tennis Star?

His parents are from Sierra Leone, but Francis Tiafoe, 16, is being talked about as the next big American tennis star. He has won the 18-and-under titles at the top two U.S. junior events, making him the first player to pull that off since John McEnroe in 1976. VOA's Mariama Diallo paid a visit to the young man who just returned from the French Open and is getting ready to play at Wimbledon next week.
