Coco Gauff was eliminated from the singles competition at the Paris Olympics Monday morning ... but her match didn't come without controversy, as an argument with the chair umpire left her in tears.
After dropping the first set 7-6(7), the 20-year-old tennis star, tied up two games a piece in the 2nd set, and with the score tied 30-30, her opponent, Croatia's Donna Vekic, served the ball ... which a line judge said was out of bounds, awarding Gauff the point.
