John O'Shea says former Queensland galloper Alberton Park will be "highly competitive" when the mare makes her debut for the Randwick trainer in Saturday's Australian Turf Club Handicap (1200m) at Rosehill.
The daughter of Stradbroke Handicap winner Thorn Park has won five of her 28 starts but has finished runner-up on 11 occasions.
O'Shea described Alberton Park as a "big mare who is easy to train" and suggested punters shouldn't read into her relatively low win strike rate when assessing her chances on Saturday.
"Her trials and trackwork are indicative that she'll be highly competitive on Saturday," O'Shea said.
"I never make my assessment of a horse until I see it work or race."
Alberton Park finished fourth behind Rain Affair in a Randwick barrier trial over 822 metres in December. The five-year-old has since won a Rosehill trial over 900 metres.
The trainer said punters could expect the five-year-old to be in the right spot in Saturday's race.
"She'll race on the speed and I would be surprised if she's not in the finish," O'Shea added.
Chad Schofield takes the reins for Saturday's assignment. O'Shea said the "extra 2kg off should give the mare an even better chance" of making a successful debut for the in-form trainer.
