Vasek Pospisil (/ˈvæʃɪk ˈpɒspɪsɪl/ VASH-ik POS-pih-sil;[3] Czech: Vašek Pospíšil, pronounced [ˈvaʃɛk ˈpospiːʃɪl];[a] known in born June 23, 1990) is a Canadian professional tennis player.

[9][10] In 1988, before Vasek was born, his parents and older brothers unlawfully drove from Czechoslovakia to Austria to escape the Communist regime.

In the summer of 1989, they finally moved to Vernon, British Columbia, a city in the Okanagan Valley, because Miloš's brother was living there after escaping his home country in the years prior.

In the summer, on the other hand, he had to play with his brothers on the poorly-maintained courts of a nearby high school and occasionally took taunts from the students there.

The decision was also made because Vasek's oldest brother, Tom, was already attending the University of British Columbia (UBC) in Vancouver, and Petr was hoping to start going to the same school.

"[15] Vasek was coached by Russian-born Vadim Korkh, who had experience working with players such as Andrei Chesnokov while he was a professor of tennis at the Central Sport Academy in Moscow.

Miloš left his brewery, moved to Vancouver, and became Vasek's full-time coach, training him at local high school courts once again.

Partnering another star junior Canadian, Milos Raonic, Pospisil won his second doubles title in December 2006, the Prince Cup in the United States.
