After dominating as a junior, Donald Young is back to some of his best form and his season ending ranking of 39 shows that.

The 22-year-old made it to the fourth round of the US Open last year – his best effort to date at a Grand Slam – which included a five set victory over Swiss Stanislas Wawrinka.

Young is coached by his parents Donald senior and Illona at their Atlanta, Georgia tennis facility. He rose to No.73 in the world as an 18-year-old and was the youngest player in the top 100.
