(AP Photo/Michel Euler)PARIS – Kristina Mladenovic's first match since her nightmarish end to the U.S. Open produced another collapse and a controversial umpire's call at the French Open on Tuesday. The French player lost to Laura Siegemund of Germany 7-5, 6-3 after serving for the first set at 5-1. Mladenovic was furious with chair umpire Eva Asderaki for not spotting a double bounce on set point. Mladenovic slowed up, looked confused, and wound up touching the net, which automatically gave the point to Siegemund.
