Andreeva races past error-prone Kostyuk to reach French Open final

Mirra Andreeva beat an erratic Marta Kostyuk in straight sets at the French Open on Thursday to reach her first Grand Slam final. The 19-year-old from Russia drew on her defeat against the same opponent at the Madrid Open earlier this year to deliver a tactical masterclass at Roland Garros, ending the Ukrainian's 17-match unbeaten run on clay.
