It is the second time the father and son combination has provided a Group 1 quinella as they reversed the finishing positions in last season's NZ Derby.
Tonight's feature race is the Palamountains Scientific Nutrition C4/5 (Race 10, 8.37pm).
It is a 520m event which is totally dominated by the powerful kennels of Lisa Ahern and Angela Turnwald.
For Ahern, Winsome Jenny is backing up from her luckless Wanganui Cup assignment.
She has recently resumed from a spell, meaning her race fitness is improving all the time.
Smash Allegro has sufficient early pace to lead this field around the first turn.
Victory Belle is likely to be stomping home late, while the remaining Ahern contender Check The Mail is likely to stick to the rail after drawing the inside box.
Turnwald produced the strong-finishing Boston Heart to win last Friday's open class 520m event.
He flew at the business end and will be hard to hold out again tonight.
Zipping Rory is better known over the staying distances, while Grader Jack, although proven at this level, is currently graded as a C4 chaser.
One has to feel for local trainer Susie Kite, who fills the remaining position with Making Time and is facing her toughest career test in this field.
