Nineteen-year-old Allen also came close to registering Ireland's fifth victory at Birmingham when he steered Twomey's stallion Romanov through to the six horse jump-off in the Grand Prix, but unfortunately two poles on the ground in the last round left him in fifth place overall.
Elsewhere, Denis Lynch brought out his new mount, Flaminia Straumann's Quote Zavaan, to claim second place at the three-star Grand Prix at Kiel in Germany. Lynch narrowly lost out to Germany's Jörg Naeve and Castro in the jump-off.
