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.

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.

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.
