Canada’s Bianca Andreescu is out of the Citi DC Open after losing to Marta Kostyuk of Ukraine in three sets, 2-6, 6-3, 7-6 (5) in the first round on Monday.
Andreescu, currently 44th in the WTA rankings, came into the match as the underdog with Kostyuk ranked 34th.
The 23-year-old from Mississauga, Ont., lost despite winning 51.7 per cent of the points, largely thanks to a dominant first set.
Leylah Fernandez of Laval, Que., plays her first-round match in D.C. on Tuesday against American Bernarda Pera after making it through qualification.
Andreescu’s attention now turns to Montreal for the National Bank Open — a tournament she won in 2019 as a precursor to winning the U.S. Open.
Her first-round match in Montreal is set for next Tuesday night.
