Kailani made it two out of two with a decisive win in the Tweenhills Pretty Polly Stakes at Newmarket.
Trained by Mahmood Al Zarooni, the daughter of Monsun had won a Yarmouth maiden on her racecourse bow last October and took the step up to Listed company in her stride.
Held-up towards the rear as stablemate Lacily cut out a decent pace given the testing conditions, Mickael Barzalona was content to bide his time.
He began to take a more prominent position inside half a mile and the pair hit the front before the dip despite drifting to their right.
Hazel Lavery, who had come under pressure some way from home, kept on best of the rest but was seven lengths adrift at the line with Lacily rallying for third.
Ouija Board was the last winner of this race to go on and claim the Investec Oaks in 2004 and the winner would need to be supplemented for Epsom in order to take her chance.
That is the plan though, with the winning trainer saying: "I wasn't surprised by that. I thought she'd like the ground. We are aiming towards the Oaks with her and we haven't decided whether she's going to run beforehand.
"Mickael liked her, he said she's a nice filly. She was a bit funny at the stalls, she seemed to hit something before she went in. But in the race she was relaxed.
"Frankie (Dettori) said not to judge Lacily on that. We need better ground for her before we know how good she is. I still liked the way she kept going."
