Vasek Pospisil (/ˈvæʃɪk ˈpɒspɪsɪl/ VASH-ik POS-pih-sil; Czech: ; born June 23, 1990) is a Canadian professional tennis player. Pospisil has a career-high World singles ranking of 25, and No. 4 in doubles. Along with partner Jack Sock, he won the 2014 Wimbledon Championships and the 2015 Indian Wells Masters men's doubles titles. He also reached the quarterfinals in singles at the 2015 Wimbledon Championships.
Vasek was born on June 23, 1990 in Vernon, British Columbia, to Miloš Pospíšil and Mila. In 1988, before Vasek was born, his parents and older brothers unlawfully drove from Czechoslovakia to Austria to escape the Communist regime. Before moving, Miloš worked as the plant manager of a dairy factory, and Mila taught in a kindergarten. Both had experience playing recreational sports such as tennis with their sons and in local tournaments.
The family lived in northeastern Austria and saved up to move to Canada despite working long hours for low wages. 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. It had a population of only about 38,000. The entire family had a meager understanding of the English language upon their arrival. Miloš worked two jobs, at a flour mill and as a machinery operator at a brewery. He began taking more interest in the game of tennis after the birth of his third son. He coached Vasek's older brothers on community tennis courts, recorded matches on television, and found tips and guidelines in tennis magazines. When Vasek was about 3 years old, he started acting as his brothers' ball boy when they practiced with their father. He also would "drag a mini tennis racquet all over the house."
