Playing career
Born in Jindřichův Hradec on 1 January 1977, Friedl grew up from the age of three in Dušejov, a village near Jihlava. He leaned at first towards ice hockey, began tennis at six and chose it over other sports at nine, joining the club in Jihlava, where he was coached by Lubomír Gerla. He began touring regularly in 1998.
A doubles specialist who named clay as his favourite surface and the return as his best shot, he won 16 ATP titles, most of them with František Čermák and Tomáš Cibulec, and reached No. 14 in 2005, the year he played Davis Cup for the Czech Republic. In 2001, unseeded with Daniela Hantuchová, he won the Wimbledon mixed doubles; he later called it the best moment of his career.
He stepped back from the tour at the end of 2011, at 34, to play club matches in the Czech extraliga, and turned to coaching. He guided Filip Polášek to the 2021 Australian Open doubles title, coached Karolína Plíšková during the 2021 North American hard-court swing, when she reached the US Open quarter-finals, and was named her coach in July 2022.
