Ireland’s Billy Twomey is off to a sparkling start at the Dublin Horse Show, winning one class and finishing second in another.

Twomey won the day's opening class, the Speed Derby, aboard Ardcolum Duke before he finished in second place with Tin Tin in the Speed Stakes.

The Speed Derby saw 19 riders battling it out for the €24,600 prize money. It was Cork-native Twomey who jumped clear in the fastest time to take top spot, one of only two combinations to produce a fault-free round.

Irish riders dominated the class with Shane Sweetnam finishing in second, Dermott Lennon coming third, Greg Broderick taking fourth and Denis Lynch claiming sixth place.

Italy’s Lorenzo De Luca and the Irish horse Limestone Grey were the winners of this afternoon’s Speed Stakes class.

Irish jumpers fared well with top further top five places for Alexander Butler and Hallowberry Cruz (fourth) and Shane Breen and Golden Hawk (fifth).

The final class of the day, the Anglesea Stakes, saw another clutch of high Irish finishes, with Anthony Condon and Chinook II leading the way in sixth place.

Shane Breen and Market Irminka took seventh, Bertram Allen and Quiet Easy 4 claimed eight and Shane Sweetnam and Buckle Up were ninth, but nobody could match Italy's De Luca, who claimed his third victory of the week aboard Halifax Van Het Kluizebos.

Meanwhile, Ireland team manager Robert Splaine named a strong line-up for tomorrow's Aga Khan Trophy.

The team is made up of Bertram Allen (Hector), Greg Broderick (MHS Going Global), Denis Lynch (All Star 5) and Cian O'Connor (Good Luck).
