World number 51 Gauff reached the third round at her home Grand Slam in 2019, soon after making Wimbledon’s last 16.
But the 16-year-old American, who had backed up last year’s promise by reaching the fourth round at January’s Australian Open, could not reproduce that form against a relentless Sevastova, 30. A second-set resurgence looked to put Gauff on track for victory against the Latvian but she lost 6-3 5-7 6-4. The Latvian – a semi-finalist in 2018 and two-time quarter-finalist – overcame her frustration at narrowly losing the second set after the pair continually exchanged breaks. She surged ahead at 5-4 up in the third to break Gauff’s serve and claim victory. Gauff was let down by a huge 13 double faults and went out when she netted a return to make her first opening-round exit from a Grand Slam tournament.
