American junior star Francis Tiafoe, 17, turns pro

Tiafoe is considering a rising star in American tennis.

Francis Tiafoe will turn professional and sign with Roc Nation Sports, the 17-year-old American junior announced on Monday. 

Tiafoe, from College Park, Md., is considered an emerging star in American tennis. No American has won a Grand Slam event since Andy Roddick captured the 2003 U.S. Open.

In 2013, a 15-year-old Tiafoe became the youngest winner in the history of the Orange Bowl International and followed up by winning the 2014 Easter Bowl. He made his ATP Tour debut in July, losing to Russia's Evgeny Donskoy 6-4, 6-4 in the first round of the Citi Open in Washington, D.C.

He is currently ranked No. 520 in the world by the ATP, after he peaked as the world's No. 2 junior player.
