Mark is currently contesting French Open juniors, and just won the first set 7-5 in his first round match against the 11th seed Cedrik-Marcel Stebe of Germany. Hopefully he can close it out in 2 sets and make the second round.
He's been playing junior tournaments on the clay as a lead up and hasn't done well, losing all his clay leadups in the first round - including a loss to Novak Djokovic's brother Marko. He did, however, compete in a Futures event in Great Britain, where he won his first round of qualifying, but lost in the second round. So not really the ideal preparation, but we'll see how he goes.
