Haley Crouser, the national high school record-holder in the javelin, has left the University of Oregon's track & field program.

The school announced the news in a release,which also disclosed the departures of former Molalla hurdler Claire Thomas, distance runner Ryan Pickering and thrower Marcus McArdle of Central High School in Independence.

UO coach Robert Johnson was quoted in the release as saying: "We wish each of these individuals the best as they pursue other opportunities. They have all been great assets to the Oregon track and field program during their time on the team."

Crouser, a sophomore, was a three-time state of Oregon Gatorade Athlete of the year while competing for Gresham High School.

In addition to winning four Oregon Class 6A javelin titles, Crouser captured two state championships in the shot and one in the hurdles.

She set the national prep javelin record of 181 feet, 2 inches in 2012.

Crouser initially trained for the heptathlon at Oregon, although this year was expected only to throw.

Her college best in the javelin was 164-5 in April of last year. She won the javelin competition two weeks at the Trojan Invitational in Los Angeles with a best mark of 158-10.

Crouser's brother, Sam, is a senior at Oregon who won the 2014 NCAA javelin championship. Her father, Dean, is a former NCAA champion in the shot and discus for the Ducks.
