The Top 11 Most Thrilling Moments of IAAF World U20 Championships

11. Deakin Volz steps up big-time to win Team USA's first-ever U20 pole vault gold 

All eyes were on Australian Kurtis Marschall, who recently cleared 5.70m to rank No. 8 on the world U20 all-time list, to win the Australian senior championships and qualify for the Olympic Games.

If there was to be an upset, no one was looking at Virginia Tech rising sophomore Deakin Volz. The Indiana native was off his form for most of his freshman year due to a wrist injury from last summer. His career best of 5.47m/17-11.5 dated back to his senior year of high school.

But he cleared 5.50m for a new PB, then followed with a miss at 5.55m and another at 5.60m as Marschall succeeded at 5.55m. It was down to the two athletes, and Volz cleared his second attempt at 5.55m, as well as his next at 5.60m.

Marschall could not clear 5.60m, and Volz won the competition, but not before taking one more attempt--this time at 5.65m--which he cleared to set a new PB and No. 3 all-time U.S. junior ranking.
