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

Canada's Leylah Fernandez produced a dominant performance to defeat Russia's Anna Kalinskaya in straight sets and win the WTA Tour's DC Open in Washington on Sunday.

Leylah Fernandez proved her resolve three times over on the way to the DC Open final — in two grueling matches against top-15 players and one against her former doubles partner and good friend, Taylor Townsend.
