The 20-year-old eclipsed his mark with a centimeter when he vaulted 6.18 meters in the Glasgow Indoor Grand Prix in Scotland.
“This was a fantastic contest,” America-born Duplantis stated. “There was such amazing energy the audience was giving me I thrive off that.”
Two-time world winner Sam Kendricks exited the contest at 5.84 meters, which Duplantis had readily handled.
With nobody left in the case, also, he flew across the bar at 6.00.
Then he had the pub moved up to 6.18m and one effort was all he desired.
Duplantis also broke the record at Torun, Poland last Saturday when an attempt of 6.17m bettered the 6.16m set by Frenchman Renaud Lavillenie at Donetsk, Ukraine in 2014.
