Second place at the 2015 Skandia Lady Junior Open in her native Sweden was the best performance of Wallin’s fledgling career, until she clinched victory in the 2016 ANNIKA Invitational Europe at Bokskogens Golf Club with a tournament total of 6-under-par 210. Proving fourth time is a charm, Wallin saved her best for the final day when making birdies on five of the first seven holes en route to victory.
