Girls Sprints & Hurdles
100m
Who: Sha'Carri Richardson, Cassondra Hall, Kira White
When: 3:10 p.m. PT
Why: The nation's best will meet for a loaded final here. Richardson is just a sophomore, but the Texas Class 4A state champion's PR of 11.34 (+1.9) makes her the second-fastest 100m runner in the nation. She'll face Texas Class 6A state champ White, whose wind-legal best of 11.63 (-0.4) ranks No. 12 this year. LSU commit Hall ranks No. 6 on the wind-legal list in 11.49 (+1.9), though the seven-time Georgia state champion won her sectional in 11.37 (+2.4). Hall is the 2015 New Balance Nationals Outdoor 200m runner-up, and owns the fastest 200m PR in the field: 23.24 (+0.9).

Why: Humphrey and Davis are familiar rivals: the Alabama and California state champions represented Team USA at the IAAF World Youth Championships last summer. Humphrey, a LSU commit, came out on top in that contest as the runner-up. Davis placed sixth in the prelims and did not qualify for the final, but won the long jump. Flash-forward a year, and Humphrey now ranks U.S. No. 6 at 13.24 (+0.9) and Davis ranks U.S. No. 7 at 13.38 (+1.2). Sloan (US No. 8, 13.40 +1.7) and Robinson (US No. 9, 13.44 +1.2) also rank in the top 10 nationally.
400m
When: 2:05 p.m. PT
Why: Waller is the top returner from the 2015 Brooks PR Invitational, where she placed third. This year, the Oregon commit set a new PR and U.S. No. 6-ranked time of 53.01 for runner-up honors at the CIF State Finals. The biggest threat comes from her future Ducks teammate, Dunmore, who ranks No. 4 in the nation with her 52.51 PR. Douglas is another runner to watch--she ranks No. 16 in the nation at 53.60 and defeated Dunmore at the Pre Classic.
