THE unflappable, imperturbable and still unbeaten Siskin delivered a long cherished first classic success for Ger Lyons as he came through his biggest test to date in flying colours to land an enthralling Tattersalls Irish 2000 Guineas at the Curragh yesterday evening.

After his exemplary juvenile season Siskin lined up as the winner of all four of his starts. His form marked him out as the best horse in the race. However, he had to prove his mettle all over again on his first three-year-old start and his first try beyond six furlongs.
