Pike High School’s Lynna Irby had the second-fastest time during 400-meter heats Wednesday in the under-17 World Youth Championships at Cali, Colombia.

Irby won her heat in 53.49 seconds, just off her personal best of 53.36. Canada’s Kyra Constantine had the fastest time, 53.20.

Also advancing was the other American entry, Symone Mason, a heat winner in 54.41. She ran 52.80 at the world youth trials, beating Irby.

Twenty-four advanced to Thursday’s semifinals. Eight will qualify for Friday’s final.

Irby has twice swept the 100, 200 and 400 at Indiana’s high school state meet.
