IVAN ALLAN strengthened his vice-like grip on the trainers' title with a 10-1 double at Happy Valley last night.
Allan took the opening event on the Lester Piggott-ridden Horse Delight and completed his brace of winners when potential Class One performer Big Arnold scored a bloodless pillar-to-post victory under Basil Marcus in the fifth.
Piggott produced a virtuoso front-running display on Horse Delight in the first for his long-time friend Allan.
The 58-year-old maestro bounced his mount out of the stalls and straight to the lead.
Despite Horse Delight hanging down the back and then facing a strong challenge in the straight, Piggott had cunningly kept enough up his sleeve to repel Happy Go Lucky's persistent challenge by a neck.
''It was a lovely ride from Lester; he really dominated from the front,'' said Allan.
