Lafayette's Armand "Mondo" Duplantis prepares to attempt 19-0.25 feet in the Class 5A Boys Pole Vault in the Allstate Sugar Bowl/LHSAA Track meet, Saturday, May 6, 2017, at LSU's Bernie Moore Track Stadium in Baton Rouge, La.

AUSTIN, Texas — Mondo Duplantis did it again.

One day shy of the two-year anniversary of breaking the world junior pole vault record, the Lafayette High School senior and LSU signee extended it Saturday in an elite competition at the 91st Texas Relays.

Competing against France's Renaud Lavillenie, the world indoor record-holder, the 18-year-old Duplantis took third with a personal-record clearance of 19 feet, 5 inches. He has held the world junior mark since going 19-4¼ at the Texas Relays on April 1, 2016, when he was a sophomore.

On Saturday, Duplantis actually cleared the same height as Lavillenie and Canadian Shawn Barber. But they went 1-2 with three and four misses, respectively, while Duplantis had five misses.

Duplantis, the son of former LSU track and field stars Greg Duplantis and Helena Hedberg, signed with coach Dennis Shaver's program in November.

Duplantis wasn't the only Louisiana standout to make a mark at the Texas Relays.

On Friday night, Parkview Baptist senior Tzuriel Pedigo claimed the javelin title with a throw of 234-11 on his sixth and final attempt of the competition.

In winning by 42 feet over Tripp Marcus of Cedar Creek (192-10), Pedigo moved into seventh place on the all-time U.S. high school list maintained by Track & Field News.

Pedigo led throughout the night after opening with a 230-1 — which was just the start of a huge series as five of his six throws measured 223 feet or better.

Also, Brusly's Ta'la Spates finished third in the girls Division I 100 meters Saturday with a wind-aided time of 11.92 seconds. Spates qualified for the final with a windy 11.88 on Friday.
