(Reuters) -Leylah Fernandez earned the biggest win of her career as she beat Anna Kalinskaya 6-1 6-2 in the Washington Open final on Sunday. After a brief rain delay in the nation's capital, Fernandez - who was just one game away from defeat in the semi-finals - overcame the extreme humidity to capture her first WTA 500 title in her first final in over a year.

Leylah Fernandez has collected the biggest title of her career at the D.C. Open with her most lopsided victory of the tournament by defeating Anna Kalinskaya 6-1, 6-2 in the final.

The 22-year-old Canadian took down Australia's Maya Joint in the Round of 32, U.S.'s Jessica Pegula in the Round of 16, U.S.'s Taylor Townsend in the quarterfinals, and Great Britain's Emma Raducanu in the semifinals on her way to the title match—where she beat Russia's Anna Kalinskaya in straight sets (6–1, 6–2).
