"Hermitage [Thoroughbreds] have been great supporters of Wexford Stables for the last five years or so. We're very fortunate to have the opportunity to go to the sales every year and buy a horse or two for them. It's great when those horses come out and win nice races."
The TAB reacted to the win by moving Rocket Spade into $8 third favouritism for the Group 1 New Zealand Derby (2400m) in March. The market is headed by Aegon and Brando, rated $6 chances.
There was no such luck for the Rocket Spade owner-trainer team in the next race on the card, the Group 2 Rich Hill Mile (1600m), in which Cha Siu Bao finished ninth after missing the start badly.
