OSTRAVA, Czech Republic -- Lukas Rosol will open against Thanasi Kokkinakis on Friday when the Czech Republic faces Australia in the first round of the Davis Cup.
Thursday's draw also pits Jiri Vesely against Bernard Tomic on indoor hardcourt in the eastern city of Ostrava.
The 133th-ranked Kokkinakis is a surprise choice for Australia captain Wally Masur, who also has Lleyton Hewitt and big serving Samuel Groth available.
Kokkinakis made the team as a substitute for the injured Nick Kyrgios.
The Czechs are without Tomas Berdych and Radek Stepanek, the stalwarts who led them to the title in 2012 and 2013.
In Saturday's doubles, Czech rookies Adam Pavlasek and Jan Mertl will face Groth and Hewitt.
Reverse singles are on Sunday.
The winner will play Italy or Kazakhstan in the quarterfinals in July.
