The 25-year-old was able to produce an excellent first round on Lordan, despite the tricky course which often demanded riders to guide their horse through double and triple combinations.

After avoiding any penalties he was assured of a podium finish, with France’s Eric Navet and the United States’ Jamie Barge delivering the only other clear rounds to force a jump-off.

Navet was first to return to the course but saw his challenge fade after a misjudgement in the early stages of the event saw his horse Catypso knock down a railing to pick up a penalty.

As a result Barge was able to put herself into pole position for the victory by delivering another faultless round, ending in a time of 49.64sec.

However, she would be made to settle for the silver medal after Nassar was able to replicate the American’s feat in a quicker time, crossing the finishing line in 48.19.

“I only kind of saw Jamie go, but people said that she didn’t go inside the Longines oxer, going away from the gate," Nasser said afterwards.

“So I knew if I slipped inside there, I didn’t have to go crazy to catch her.

“I did six strides in the first line, eight in the second line; my horse has small stride.

"But then it was just a matter of jumping the last two jumps clean.”

Following the completion of the West Coast events of the inaugural North American League, attention will turn to the final East Coast competition on February 27 in Ocala, Florida.

After the event, the top seven athletes from the East Coast and three from West Coast will advance to the FEI World Cup Jumping Final, along with the best two riders from Canada and Mexico.

The winners of the 13 remaining leagues around the world will also advance to the Final in Gothenburg from March 23 to 28.
