Madison Keys suffered a first-round defeat at the DC Open on July 28. The sixth seed lost to Liudmila Samsonova 3-6, 6-4, 6-4 after leading in the deciding set.
Keys started strongly by winning the opening set but could not maintain momentum. Samsonova improved her serve and broke Keys twice in the third set to complete the comeback after two hours and 24 minutes.
Fans expressed frustration on social media over the result. One said Keys appeared to sell the match, while others noted repeated forehand errors and a familiar collapse from a 4-2 lead.
Keys will next compete at the National Bank Open in Montreal. The tournament marked an early hard-court exit for the American player.
