The Stuttgart ATP event on Sunday issued an apology to World No.78 Nick Kyrgios after an ugly racial incident during his semi-final loss to Andy Murray. Kyrgios was insulted mid-way through what turned into a 6-7 (5/7), 2-6 loss to three-time Grand Slam winner Murray on Saturday.

Kyrgios was penalised a point and then a game for unsportsmanlike conduct early in the second set, smashing a racquet before an angry exchange with a group in the crowd. The 27-year-old Australian said he had been the victim of racism.
