A 16-year-old from North Texas stunned the world Sunday at the U.S. national track championships and punched his ticket to the World Championships. Cooper Lutkenhaus, a rising junior at Northwest High School, finished second in the men's 800 meters with a time of 1:42.27. Lutkenhaus finished just behind 2019 world champion Donavan Brazier. Though he didn't get first, Lutkenhaus snagged a world record: the fastest performance for an athlete under 18. His time was also the fourth-best in U.S. history and the fifth-fastest in the world. The silver medal finish qualifies Lutkenhaus for the World Championships, which will be held in Tokyo, Japan, in September. “I was really seizing the moment, racing the best guys in America and globally,” Cooper said following the race, according to Northwest ISD. “I was just going out there and having fun and just trying to see what I can do.” FULL STORY: https://www.wfaa.com/article/sports/north-texas-teen-qualifies-world-championship-after-finish-us-nationals/287-b2859501-a88f-48df-b0c7-68012975157f
