8217 Dominikhašek           Discovered 1995 Apr. 21 by P. Pravec and L. Sarounova at Ondrejov.
Named in honor of Dominik Hašek (b. 1965), goalkeeper, and the Czech Olympic hockey team, winners of the gold medal at the 1998 Winter Olympic Games in Nagano. Although the success was basically due to teamwork, Hašek's contribution was the most significant. This great win in "the hockey tournament of the century" was widely appreciated by the Czech people and recognized as one of the greatest achievements in the history of Czech sport.
