World indoor records from Hugues Fabrice Zango and Ryan Crouser, plus a handful of world U20 records set by teenage talents Sasha Zhoya and Erriyon Knighton in 2021, are among the latest marks to have been ratified.
Four star performers from the Tokyo Olympic Games have had their record-breaking marks from earlier in the season ratified.
As the 10-day US Olympic Trials closed in Eugene, 21-year-old Sydney McLaughlin became the first woman to break the 52-second barrier in the 400m hurdles.
Grant Holloway came within one-hundredth of a second of a world record in the 110m hurdles and Rai Benjamin came within five-hundredths in the 400m hurdles. Gabby Thomas made history in the 200m, as did DeAnna Price in the hammer.
Erriyon Knighton improved his own world U18 best as well as the US U20 record in the first round of the 200m at the US Olympic Trials on Friday (25), winning his heat in 20.04 (-0.2m/s).
After a string of 200m victories and some swift – albeit wind-assisted – times over 100m in the past two months, 17-year-old Erriyon Knighton finally entered the record books with his 20.11 200m win at the Duval County Challenge, a World Athletics Continental Tour Bronze meeting, in Jacksonville on Monday (31).
