The Prefontaine Classic fields are so stacked that it is the best Diamond League meet so far this season, even with the absences of Allyson Felix, Genzebe Dibaba, Matthew Centrowitz and Galen Rupp.
The Diamond League’s lone trip to the U.S. doubles as the best gauge of form this spring ahead of the U.S. Olympic Trials (July 1-10).
The annual meet in Eugene, Ore., is a Friday-Saturday affair:
Friday
USATF.TV — 11:20 p.m. ET
Saturday
NBCSN and NBC Sports Live Extra — 3:30-5 p.
