Lance O’Sullivan knows the NZ Derby form hasn’t looked too flash this autumn but he’s hoping star colt Rocket Spade can buck the trend in Saturday’s Australian Derby (2400m) at Randwick. All three of the NZ Derby placegetters will line up in the $2 million staying test on Day One of The Championships after Rocket Spade edged out Milford and The Frontman in the NZ feature last month. Rocket Spade will have his first Australian run in the Australian Derby but it’s the performances of the other two so far across the Tasman that have created some cause for concern.
