At the U.S. track championships at Icahn Stadium, Sha’Carri Richardson and Noah Lyles advanced to the 100m semifinals after their first-round wins. Richardson clocked 10.90 in a cautious, energy-conserving run as the field awaits Friday’s final, benefiting from reigning world champion Melissa Jefferson-Wooden focusing on the 200m. Lyles posted 9.97 to edge Ronnie Baker, with Christian Coleman posting the day’s fastest 9.96 in the opening heat. The session also featured drama in the men’s event, including a sequence of false starts and the disqualification of Ja’Darien Parker, with Courtney Lindsey winning the restart. Icahn Stadium’s track scene is steeped in sprinting history, echoing Usain Bolt’s world-record 9.72 there in 2008. Rivalries and past incidents, such as Bednarek’s ongoing contests with Lyles, add extra intrigue to the competition.
