Did anyone else just witness Cooper Lutkenhaus, the high school phenom, shock the 800m field? At just 16, he clocked a jaw-dropping 1:42.27—smashing the world junior record and outpacing pros like Josh Hoey. That’s now the fourth-best U.S. time ever! Lutkenhaus has officially punched his ticket to the World Championships in Tokyo. Is this the start of a new American middle-distance rivalry? The future is looking bright for this kid! #Sports #CooperLutkenhaus #TrackAndField
