Overview
- Ethan Katzberg won the hammer in Eugene with a throw of 83.33 metres, which set a Diamond League record and was the world lead for the season.
- Merlin Hummel, the world silver medallist, finished third with 79.01 metres, showing solid form but below his personal best from earlier this year.
- Robert Farken improved the German mile record to 3:47.76 and Mohamed Abdilaahi ran a German best of 8:10.34 over the rarely contested two miles, finishing second to Parker Wolfe.
- Olympic champions produced tune-up performances: long jump gold medallist Malaika Mihambo recorded a season best of 6.92m for fifth, shot put winner Yemisi Mabry reached 19.14m for fifth, and Gesa Felicitas Krause ran 9:07.50 for sixth in the steeplechase.
- These results at the Prefontaine Classic give selectors and athletes concrete benchmarks as they finalise form for late‑July national championships and the European Championships in mid‑August.
