Sergiy Stakhovsky

Sergiy Eduardovych Stakhovsky (Ukrainian: Сергій Едуардович Стаховський, pronounced [serˈɦij stɐˈxɔu̯sʲkɪj]; born January 6, 1986) is a Ukrainian former professional tennis player. Stakhovsky turned professional in 2003 and played mostly at the Challenger level from 2005 to 2008. His career-high rankings were World No. 31 in singles (September 2010) and No. 33 in doubles (June 2011).

Stakhovsky won his first career title in March 2008, as a lucky loser ranked No. 209, defeating top seed Ivan Ljubičić in the final, thus becoming the first lucky loser to win a title since Christian Miniussi in 1991. He is perhaps best known for defeating eight-time winner and defending champion Roger Federer in the second round of the 2013 Wimbledon Championships, ending the latter's record run of 36 consecutive major quarterfinals.

He is the elder brother of tennis player Leonard Stakhovsky. He was coached by Burghard Riehemann. Stakhovsky retired from tennis in January 2022, and following the Russian invasion of Ukraine he joined the Ukrainian Army.

Stakhovsky reached career-high world rankings of No. 28 in singles and No. 32 in doubles in 2003. In 2004, he had his best junior result, losing in the final of the US Open to Andy Murray, beating Donald Young in the first round. In 2002, he beat Novak Djokovic in the quarterfinals of Luxembourg, before losing to Dudi Sela in the final.

Stakhovsky played his first ATP-level singles match in October in Moscow's Kremlin Cup. After beating Alejandro Falla in qualifying to reach the main draw, he lost to Nikolay Davydenko in the first round. He then reached the quarterfinals of a couple Challengers to finish the year ranked No. 335 in singles.

Stakhovsky began 2005 where he left off, qualifying into the ATP stop in Qatar in January and losing to Lee Hyung-taik in the first round. In February, he won his first ATP-level singles match, qualifying into the main draw, where he beat No. 100 Christophe Rochus and No. 29 Mario Ančić before losing to No. 37 Robin Söderling in the quarterfinals. He spent most of the rest of the year having moderate success at the Challenger level, but did qualify once more into an ATP tournament in Russia in October, reaching the second round. He finished the year ranked No. 173 in singles.

In doubles, he won two Challenger tournaments, in Spain in July and Prague in November.

Stakhovsky had a rough start to the year, losing in the first round of qualifying at three straight ATP stops. By May, his ranking had slipped back to No. 260 before he began making progress again on the Challenger Tour. Semifinal results at major Challengers in Spain and Istanbul in July got his ranking back to No. 181.
