Berdych splits with coach Tomas Berdych has split with coach Daniel Vallverdu just ahead of this month's French Open due to his disappointing results in the recent past. The 30-year-old Berdych is yet to reach a single final this season and has already lost 10 times, including a disappointing second-round loss to world No. 71 Damir Dzumhur in the Monaco Masters. World No. 8 Berdych, who started working with the former coach of world No. 2 Andy Murray in December 2014, said in a Facebook post he was yet to decide on his new coach. "My results lately have not been what I expected. As I am not a tennis player at the beginning of his career I have to act quickly when I feel that I need a change," Berdych said. Berdych is currently training in Paris and with the second Grand Slam of the year starting in Roland Garros next week. Turkey to host new event The ATP says a new men's grass-court tournament will be held in Turkey next year as a warm-up to Wimbledon. The tournament will be held in Antalya from June 25-July 1. It will feature a 28-player singles event and 16-pair doubles draw and offer 482,000 euros ($540,000) in prize money. Seven grass courts will be built at the Kaya Palazzo Belek hotel resort under the guidance of Wimbledon's All England Club. It's the latest addition to the grass-court season following the introduction of a three-week gap between the French Open and Wimbledon. Also next year, the grass-court tournament in Nottingham, England, will return to Eastbourne and take place the same week as the Turkish event. It will be the second ATP tournament in Turkey, which has hosted the Istanbul Open the past two years. — Agencies
