Lindblad, a two-time ANNIKA Award finalist, fired a 5-under par 67 on the last day of play to finish 12-under par for the tournament to earn a three-shot victory over Alexandra Forsterling of Germany, who posted 279 and moved up two places after a 3-under 69 final round.
Four more birdies in the next eight holes put Lindblad 13-under. Kjellker and Wallin, Lindblad's playing partners in the final group, struggled to keep the pressure on after making a number of bogeys, allowing Lindblad to open up a five-stroke lead through 13 holes.
Despite a bogey on the 14th, Lindblad comfortably parred her way in to post a -12 total and claim the European title by three strokes. She becomes the first Swedish player to win the event since 2009.
"It's been a great day, I played great today," said Lindblad after her round. "I think I missed my first green on hole 12, so I hit a lot of greens at the beginning and had a lot of good chances for birdies."
"It was very cool having three Swedes in the last group, just walking around speaking Swedish was very unusual for an international tournament."
The victory earns the Swedish player her second appearance in the AIG Women's Open at Carnoustie in August, having successfully come through Monday qualifying in 2019.
