Jerôme Kym is just 15 – 16 next week.
He’s never played a pro match and, ranked No. 298 in the juniors, has never played in a tourney above a Grade 2 in a year and a half at the ITF level.
But a Swiss team without Federer or Wawrinka selected him for its qualifier against the Russians, who brought a quality roster.
The kid, along with Henri Laaksonen, pulled off a major upset as they defeated Andrey Rublev and Evgeny Donskoy 4-6, 6-3, 7-6 (1) in doubles to keep Switzerland alive after an 0-2 first day.
It was in vain. But watch out for the kid.
