Weerts took third in the 5000 meters with a time of 14:09.02 after being seeded 10th. The top five individuals in each event advance to the nationals set for June 10-13 in Fayettville, Ark. It was the only track event with a finals race. The rest will be run on Saturday.

On the downside for Auburn, the women's 4x100-meter relay team, which ranked fourth nationally, was disqualified after an exchange problem and can't compete in the nationals.
Auburn head coach Ralph Spry said, "Unfortunately our first event was the women's 4x100 relay and we just didn't get the baton around, but after that we really cleaned up.
"Everybody that we were expecting to get through got the job done. We're doing what we came here to do. That's the most important thing is to get to the finals to give yourself a chance to finish in the top five. We came here to get a lot of people qualified for the national championships and right now we're on pace to do that."
