Cade Flatt backed up all the talk on Friday.
Flying off the turn in the final 200 meters at the Trials of Miles: Track Night NYC men's A 800m section, the Marshall County (KY) senior -- who found himself in the spotlight in March after a wild interview after a national title win at New Balance Nationals Indoor -- flew into the finish line in the second-fastest 800 meter performance of all-time, finishing fourth in a time of 1:46.51 at Icahn Stadium.
That time is currently World top 50 performance.
He's the second high school athlete to ever go under 1:47 in history. He also followed up a performance of 1:47.04 from April.
He was just 0.05 seconds off of Michael Granville's high school national record of 1:46.45, which was last achieved in 1996 at the CIF State Outdoor Track and Field Championships.
But afterward, Flatt was not disappointed.
"I think I'm the best ever," he said.
Flatt opened up the first quarter in impressive fashion, clocking roughly a 51-second first lap. That marker ultimately set up a wild last lap which largely just needed the Ole Miss recruit to close in 55 seconds.
That he did.
"I still got time," he told an interviewer afterward. "I'm not done yet.
"I was coming on those guys," he added.
Indeed, Flatt is not done.
Next week, the high school senior will head to his outdoor state championships in Kentucky and then will follow with performances at the USA U20 Championships -- or perhaps at this point, maybe even the USA Championships.
