Four ISU track and field athletes competed in Eugene, Ore., on day one of the NCAA Outdoor Championships, and all four made statements in the opening round.

Senior Ejiro Okoro won her heat in the 800-meter preliminary, finishing with a time of 2 minutes, 4.28 seconds. Her time, the best of her career, is now the fourth-best 800-meter time in program history.

Okoro finished fourth overall in the event and will compete in the final June 13.

Senior Ese Okoro, Ejiro’s sister, sprinted her way to a spot in the 400-meter hurdle final on day one. She finished third in her heat with a personal best of 56.67 seconds. Ese finished fifth overall in the event and will compete in the final on June 13.
