Jamaica’s Charokee Young continued her fine form to start this season by winning the Women’s college 400m in a personal best and world leading 49.87 at the Tom Jones Memorial Invitational in Gainesville, Florida on Saturday.

Young, competing for Texas A&M, finished comfortably ahead of teammate Tierra Robinson-Jones (50.89) and Florida’s Talitha Diggs (51.93).
