Godolphin have supplemented Kailani into Friday's Investec Oaks at a cost of £20,000 and trainer Mahmood Al Zarooni feels she's ready for such a test.
The filly will be bidding to emulate her mother, Kazzia, who won the Classic 10 years ago and entered the Oaks picture after an easy victory in the Pretty Polly Stakes at the Newmarket Guineas meeting, a race Ouija Board won before she followed up at Epsom in 2004.
"Kailani has done nothing wrong in both her starts to date and we decided to take a chance by running her in the Oaks," the trainer said.
"She worked really well on Friday and I think that she has improved since her run at Newmarket. We were quite easy on our horses at the beginning of the season and a lot of them have come on for their first start.
"She won her maiden on good ground but we cannot say 100% whether she will handle good to firm until we run her on it.
"It's the same with her handling the course, although I expect that the step up to a mile and a half will suit her. We don't know how good she is and we are waiting for her to surprise us."
