Within hours of breaking Jim Ryun’s collegiate 800-meter record and winning his first NCAA title, Texas A&M freshman Donavan Brazier was already facing questions about his future: Would the 19-year-old phenom chase an under-20 crown at this summer’s IAAF World Junior Championships? Or would he compete at the U.S. Olympic Trials for a chance to represent Team USA in Rio?

The answer will have to wait. “I don’t know. It depends what my coach says,” Brazier told the press following Friday’s race. “I know Coach [Pat] Henry likes the juniors to run juniors while they can, because you only have so many years of eligibility.”

Brazier’s NCAA record time of 1:43.55 is the fastest under-20 performance in the world this year by more than a second. But it’s also the fastest time by any American in 2016, making Brazier a clear podium contender for the U.S. Olympic Trials, should he decide to enter.

Brazier isn’t ruling out the possibility that he might compete at both events.

“Six days [apart]?” he said, referencing the gap between the U.S. junior 800-meter final and the start of the Olympic Trials. “I could, but I don’t know that I would.”

If Brazier does compete at the Trials, he won’t be the only NCAA champ chasing a spot on the U.S. Olympic team. Here are three other runners who could make a splash in Eugene.

Raevyn Rogers

With less than a second separating the U.S.’s first and 11th-ranked 800-meter runners, it’s anyone’s guess who will land on the podium at the Trials. But after the NCAA championships, Raevyn Rogers is looking like an awfully good bet.

In Saturday’s 800-meter final, the University of Oregon sophomore showed off her elite finishing speed over the last 150 meters, gapping the field by nearly two seconds and winning her second straight NCAA title.

“In prelims, I kicked too late,” Rogers said after the final. “I just wanted to lay it all out there.”

Rogers’ winning time of 2:00.75 is only the eighth-fastest clocking by an American this year, meaning she still faces an uphill battle to qualify for the Olympics. “Everybody’s talented,” Rogers said of her competition. “It’s going to take a lot of heart.”

Courtney Frerichs

Courtney Frerichs, from the University of New Mexico, dominated the women’s steeplechase field on Saturday, winning her first individual NCAA title and setting a new collegiate record of 9:24.41.

“My coach told me four years ago that I could be an NCAA champion [and] I thought he was a little crazy,” Frerichs said after her race, noting that her personal best then was only 10:34. “But he believed in me this whole time.”

Next month, Frerichs, who graduated, will chase her first Olympic berth against a deep and talented U.S. steeplechase field, led by American record-holder Emma Coburn and 9:18 steepler Leah O’Connor. Frerichs’s time currently ranks third in the U.S., ahead of Ashley Higginson, Jamie Cheever, and 2012 Olympian Shalaya Kipp.

“I’m excited to see what happens [at the Trials],” Frerichs said. “I think today gave me a lot of confidence that if I get in a fast race, I can run a lot faster.”

Clayton Murphy

Only two days after winning the NCAA 1500-meter title—and less than 12 hours after launching his professional career—Clayton Murphy toed the 1500-meter start line at the Portland Track Festival hoping to hit the Olympic qualifying standard of 3:36.20.

Murphy won the race handily, finishing ahead of Jordan McNamara, Dorian Ulrey, and 2012 Olympian Matthew Centrowitz, among others. But his time of 3:36.23 made it a bittersweet victory. “I’m super disappointed that I was [0.03 seconds] off, but I ran a PR and walked away with my first professional win,” he said. “I didn’t leave anything out there.”

In 2015, Murphy advanced to the 800-meter semifinal at the IAAF World Championships in Beijing. But Murphy says it’s still up in the air whether he’ll target the 800 or the 1500 at this year’s Olympic Trials.

“I guess the decision now becomes whether I want to run another 1500 and get the Olympic standard, or whether I want to stay with the 800,” he said. “I don’t know…The next two days are definitely going to have some car rides around Portland trying to decide.”

Meanwhile, two dark-horse candidates to watch at the Trials are Stanford’s Sean McGorty and Brigham Young University’s Shaquille Walker. McGorty ran 13:26.10 in the NCAA 5,000-meter final to finish second behind repeat champion Edward Cheserek, of Oregon.

Walker finished third in the NCAA 800-meter race, but his season-best time of 1:44.99 currently ranks third in the U.S.
