WASHINGTON (AP) Italy's Camila Giorgi upset fifth-seed Eugenie Bouchard in straight sets, 7-5, 6-4, on Tuesday in the first round of the Citi Open.
It's the fourth time in the Canadian's past 10 tournaments that she has lost her opening match. Bouchard most recently reached the round of 32 at Wimbledon before losing to Dominika Cibulkova.
Bouchard battled back from a 4-1 first-set deficit to tie it at 4- and 5-all before Giorgi held serve and broke her to win 7-5.
When Bouchard was broken to fall behind 4-2 in the second set, she threw her racket to the ground. After battling back to get it to 5-4, she was broken again to lose the match.
The 24-year-old Giorgi will face either Tamira Paszek or Lauren Albanese in the second round.
