Mononucleosis slows down Kozlov

Everything looked aces for 2014 Orange Bowl champion Stefan Kozlov as he headed to the top 100 in 2017. The 20-year-old was part of that American next wave with Frances Tiafoe, Taylor Fritz, Michael Mmoh, and Tommy Paul.

But while Tiafoe, Fritz and Stefanos Tsitipas (his victim in that Orange Bowl final) are in Milan this week, Kozlov is ranked … No. 414.

One explanation comes from father Andrey, who was competing at the ITF World Seniors Championships in Florida a few weeks ago.

Kozlov told the ITF website his son has battled mononucleosis for the past six months.
