Finland’s Matilda Castren and Malaysian Kelly Tan combined to shoot a 6–under 64 on Wednesday to jump into the lead after one round of action at the Dow Great Lakes Bay Invitational in Midland, Mich.
The duo turned in a bogey-free card while tallying six birdies to edge three other groups by one stroke. Castren and Tan caught fire on the back nine, securing birdies on half of their final six holes.
