THE EI90 at Frankfort Stud proved the theory of lucky number three for junior rider Maya Byrne, when she topped the leader board on only her third run with the 11-year-old traditionally-bred Tranquil Master.

The cross-country time had less of an influence here than it did at the higher levels, and both Byrne and second-placed Keira Crowther with OK Lucky Diamond finished on their dressage scores of 25.8 and 27.5 respectively. Chloe Lalloo and the Connemara Kildromin Mentor finished third with just 3.2 time faults to add to their first phase score of 29.3.
