Trainers Stephen Autridge and Jamie Richards believe it is only a matter of time before Shillelagh makes her mark at stakes level.
The Savabeel four-year-old is fashioning a tidy record and she won for the fourth time in her six start career with an impressive display to triumph in the Ford Kuga 1200 at Ruakaka yesterday.
"We think she's a very good mare and we've had an opinion of her for a while now," Richards said. "She's a lovely mare to have in the stable."
Unplaced and subsequently treated for a mild attack of colic when resuming at New Plymouth last month, Shillelagh settled back off a hot pace and she rounded off powerfully in the run home for a stylish victory.
Super Lethal made a good fist of his return to racing with his second placing after making the running and Lewis Carroll took third money.
