Italy break world record in mixed 4x100m relay, Poland set national record — then a DQ

At the junior World Athletics Championships in Eugene, Italy broke the world record in the mixed 4x100m relay, while Poland set a new national record. The finish-line classification was not the final one — judges disqualified one of the finalists. The mixed 4x100m relay made its debut at the junior World Championships and will feature at the Los Angeles Olympics.
