The victory for Kitaguchi put an explanation point on what was a dominant season for the Japanese star, who came into the meet leading the race to claim the Diamond League trophy. She established the world lead of 67.38m/221-0 last week at the Diamond League Memorial van Damme in Brussels and, also won the gold medal at the World Championships in Budapest in August.

“I’m so happy about this win and also World Championships win; it’s really amazing,” Kitaguchi said.

Kitaguchi opened the competition with a safe first throw and sat in third place behind Little and Peeters. But on her second throw, she surged into the lead with a mark of 63.78m/209-3 and never looked back.

Maggie Malone, the lone American to qualify for the finale, finished in fourth place with a final throw of 60.42m/198-2.
