# Ján Krošlák

Ján Krošlák (born 17 October 1974) is a former tennis player from Slovakia, who turned professional in 1993.
He represented his native country at the 1996 Summer Olympics in Atlanta, United States, where he was defeated in the first round by America's MaliVai Washington. The right-hander reached his career-high ATP singles ranking of world No. 53 in September 1999. He won two singles titles on the ATP Tour.
In the 1998 Davis Cup, he played with Martin Hromec.

## Political career

In 2020, Krošlák was elected an MP of the National Council of Slovakia, representing the Ordinary People and Independent Personalities along with fellow former tennis players Karol Kučera and Romana Tabak. He departed from the OĽaNO caucus in 2021, joining We Are Family parliamentary group. In December 2022, Krošlák was one of the crucial MPs in a vote of no confidence to Heger's Cabinet. He stated he would declare no confidence and, in so doing, go against the We Are Family parliamentary caucus. He departed from the caucus along with Martin Borguľa on 13 December and announced that he was considering a move to a different political party ahead of the next parliamentary elections, naming HLAS-SD as a potential destination.
