Armand Duplantis of Lafayette High School

AUSTIN, Texas — Lafayette High School junior pole vaulter Armand Duplantis outdid himself Saturday in the Texas Relays.

Competing in the men's pole vault elite, Duplantis cleared the bar at 19 feet, 4¼ inches to easily take the title and shatter the world junior record by four inches.

The mark came three weeks after the 17-year-old Duplantis soared 19-1 at the New Balance Indoor Championships and a little more than a month after going 18-9¼ for the national high school record at the LSU Last Chance Qualifier.

He had a best of 18-10¼ a week later at the Millrose Games in New York.

On Saturday, Duplantis cleared 19-¼, then passed at the next height — 19-2¼ — before going 19-4¼ on his final attempt.

The old world outdoor junior record of 19-¼ was set by Maksim Tarasov of the Soviet Union in 1989 and matched by Germany's Raphael Holzdeppe in 2008.
