Damien High graduate Zach Shinnick has had quite the summer.
Last month he won the USA Junior National championship in the 400 meters and last week in Peru he placed third in that event in the Pan American Junior Championships which serve as the world championship for athletes 20 and under.
He closed out the meet as part of a 4×400 relay that posted a 3:00.33 for a new American and World Junior record. Shinnick, who is headed to USC, ran a 44.71 on the second leg.
That mark bested the 3:01.09 in 2004 by the quartet of Brandon Johnson, LaShawn Merritt, Jason Craig and Kerron Clement.
Also on the record-setting relay were Georgia high schooler Brian Herron, Texas Tech signee Sean Hooper and Josephus Lyles, a Virginia native who runs professionally for Adidas.
