Jasmine Charles (center) dropped just over a full second from her 2018 best.
Two seconds is a lot of time in the 100 Hurdles, given that there's only 100 meters to make gains, and only 10 opportunities to remain efficient over the hurdles.
But a staggering five 100 hurdlers within the Top 200 chopped over two seconds from their 2018 personal best.
Taking the cake this year was Ashley Kenny.
The Lutheran junior nearly had a three-second leap, but hey, 2.93 seconds is more than good enough. She capped her sophomore season with a 19.10 best, and then went to work. This year she opened up with a PR of 17.36 before inching her way down to 16.17. She finished 10th in the prelims at the State meet, just missing out on the final.
Just over a tenth of a second behind in terms of improvements was Deven Quintanilla.
The Pine Creek junior only races the event once last year, and it was a 18.69 effort. This year she went to a whole other league, dipping under 18 seconds nine out of 10 times, and topping off with a 15.90 PR for a leap of 2.79 seconds.
The next three to cap off this list of two-second improvements include Ashley Long, Anneliese Metzger, and Ella Hicks.
Long made a leap of 2.28 seconds, while Metzger improved by 2.18, and Hicks captures a 2.03 jump.
