Tennis - 6th-ranked Karolina Pliskova parts with coach Jiri Vanek
US Open finalist Karolina Pliskova has parted ways with coach Jiri Vanek, ending a partnership that earned five WTA titles. The decision by the 24-yearold Pliskova came after she helped the Czech team retain the Fed Cup title with a 3-2 victory over France over the weekend. With Vanek, who joined her in 2014, Pliskova jumped into the top 10 and is currently ranked sixth. She reached the U.S. Open final and qualified for the WTA Finals for the first time this year. It was not immediately clear who would replace Vanek.
