LAUSANNE, Switzerland -- Olympic jumping champion Steve Guerdat of Switzerland has reached No. 1 in the equestrian world rankings for the first time.

The International Equestrian Federation published monthly rankings on Tuesday with Guerdat climbing from third position to succeed Swedish rider Rolf-Goran Bengtsson, who was fourth.

Guerdat used points he earned riding Nino des Buissonnets to victory last month at the Grand Prix in Rio de Janeiro, the 2016 Olympics host city.

The 30-year-old Swiss also teamed with Nino des Buissonnets to win individual gold at the London Games in August.

Guerdat says on his official website that "to reach this first place the same year as my Olympic title is unbelievable."

In the latest rankings, Nick Skelton of Britain, an Olympic team gold medallist , was second. Germany's Christian Ahlmann was third.
