How about White Lake Lakeland (MI) High junior Grace Stark? In quite possibly the most competitive 60 meter hurdles field this indoor season thus far, Stark raced to a new US No. 1 mark of 8.12 seconds on Saturday at the UK High School Indoor Invitational to knock off former national-leader Tia Jones and US No. 1 55mH leader Masai Russell.
She wasn't done, though.
She added another personal best in the 60m, going a US No. 5 mark of 7.41 seconds at the distance to take another win. She knocked off 0.06 seconds from her top time a week ago at the SPIRE Scholastic Showcase.
As Stark has shown all season, she's been money when on the line against premier competition. Check out both races of the junior.
