Burke High School's Raven Saunders and Hailey Sweatman of James Island Charter High School put on winning performances at the New Balance Nationals outdoor track and field championships this weekend in Greensboro, N.C.

Saunders, holder of the indoor and outdoor high school records in girls shot put, turned in a throw of 56 feet, 7 1/2 inches to win the under-20 title and set a New Balance Outdoors record, matching the national indoor record she set in April.

Sweatman, who won the Class AAA state championship in the girls pole vault this year with a jump of 11-0, bettered that effort with a vault of 12-3 1/2 to win the emerging elite division at the New Balance meet.
