WIMBLEDON (NYTIMES) - Coco Gauff's dreamy first Wimbledon came to an end in the fourth round on Monday (July 8).

Gauff, a precocious 15-year-old American, was defeated, 6-3, 6-3, by Simona Halep, the No. 7 seed and a former No. 1 player, who proved too consistent and resourceful from the baseline for the 313th-ranked youngster.

But Monday's defeat hardly erased the impact that Gauff made in the first week of her first Wimbledon. After receiving a wild card into the qualifying tournament, she won six straight matches: three in qualifying and three in the main singles draw. She defeated five-time Wimbledon singles champion Venus Williams and veterans Magdalena Rybarikova and Polona Hercog.

But Halep, an established top player in her prime, was a step up. Though Gauff was often brilliant in the early going Monday on the same No. 1 Court where she defeated Williams and Rybarikova, she could not sustain her level of play. Her forehand, a fine shot but not yet a great shot, often was the weak link in the long and athletic baseline rallies.

Gauff was the youngest player to reach the fourth round of the women's singles at Wimbledon since Jennifer Capriati reached the semifinals in 1991 at 15.
