A second successive Group 1 victory for superstar jockey Jamie Kah in front of a massive home crowd on Goodwood Day was the fitting finale to a massive Adelaide Racing Carnival.

Benedetta has won her first Group One, taking out The Goodwood at Morphettville.

Jamie Kah is the new rider of the Jason Warren-trained Benedetta in the $1m Group 1 Goodwood (1200m) at Morphettville next weekend.

Classy mare Benedetta took the first step towards the Group 1 Sangster Stakes with her brilliant win in the $150,000 Group 3 Sportsbet R N Irwin Stakes (1100m) at Morphettville on the weekend.

Trainer Jason Warren says Benedetta could not be in any better order ahead of her first-up assignment at Caulfield.
