Drastic improvement has been good to sophomores.
Long Beach Poly sophomore Xai Ricks currently leads the country with year-over-year improvement in the 400m, as he's chopped a full 3.29 seconds off his PR from last year.
He's one of three boys to have achieved a three-second improvement in the 400m thus far this year. Meanwhile, in the girls field, a total of four girls have improved by at least four seconds, including national-leader Layden Jack of Scotlandville, a sophomore from Louisiana who has posted a 4.57-second improvement on her current PR of 55.8 seconds.
All four of the top girls in YOY growth have run at least 56.1 or faster.
Of course, that's not all. Check the full field of athletes in the links below.
