How much did the girls sprinters of Pennsylvania since last season?
We analyzed the data -- 5000 deep in each event -- to determine which girls saw the most improvement from the 2017 outdoor season to the 2018 outdoor season. We noticed a number of standouts, like 2.86 seconds in the 100 meters and over 6 seconds in the 200! Abington's Rorie Spencer (above) dropped .80 in the 100 meters since last season.
The lists only include athletes who have registered times in 2017 and 2018 in the particular event.
The lists are sorted with the top improvements in each event at the top. Check out lists in the sprint events -- 100, 200, and 400 -- below.
