CIAN O’Connor’s winning streak continued at Treffen’s five-star show in Austria on Saturday as the Meath-based rider guided the 10-year-old gelding Callisto to victory in the 1m55 jump-off class.

The London Olympic bronze medalist was drawn first to go in a 13 horse jump-off, went clear and laid down what proved an unbeatable time of 40.98 seconds.

Speaking in the prize giving where he collected €15,500, O’Connor said: “Sometimes it’s a disadvantage to go first in the jump-off but today it worked out in my favour. I had a plan and I stuck to it and thankfully those who followed were not able to match it.”

Callisto, who is by the stallion Quasimodo Z, is owned by Ian O’ Grady, Philippe de Balander & Ronnoco Jump Ltd.

The final line-up included a host of the world’s top riders, including European champion Jeroen Dubbeldam, who finished second, Sweden’s Peder Fredricson, and Germany’s Marcus Ehning.

Wexford’s Bertram Allen was last to go in the jump-off with Dino W and took seventh place when lowering one fence against the clock.

This latest win for Cian O’Connor came on the back of another victory with the 12-year-old stallion Copain du Perchet CH in Treffen on Thursday, while last weekend he claimed the five-star Grand Prix at Sopot in Poland with the stallion Good Luck.
