Ice-cool Mensik reaches Paris semi-finals, red-hot Andreeva and Kostyuk set up meeting

PARIS, June 2 : Jakub Mensik battled past Brazilian breakout star Joao Fonseca with a 6-4 6-3 7-6(3) win to make the semi-finals of the French Open on Tuesday and become the youngest Czech man to reach that stage at a Grand Slam.
