Adelaise pulled out all the stops in the Virgin Bet Daily Price Boosts Snowdrop Fillies’ Stakes to give Joseph O’Brien a raiding winner at Kempton on Saturday.

The five-year-old produced some consistent performances in several competitive heats last term, but finally secured a valuable black type victory in the hands of William Buick at the Sunbury track.

Sent off the 100-30 second favourite for the one-mile Listed event, Adelaise was ridden along by her pilot with two furlongs to run, but soon hit top gear as she began a ding-dong battle to the line with 5-2 market leader Choisya.

There was little to separate the two protagonists inside the final half furlong, but the Irish challenger got her head in front where it mattered most to make O’Brien’s first UK Flat runner of the year a winning one.

Buick said: “She was a bit in my hands early and a bit fresh, but she was always in a nice rhythm and I attacked early in the straight.

“We didn’t go overly quick and I knew she would stay all the way to the line. She definitely got headed, so she had to show true grit. I think a mile is her trip and she may get a little bit further, but we will see.

“I’ve ridden a winner for Joseph before and it’s nice to get a call-up from him – he doesn’t come over here for nothing.

“I think this was very important for both her and connections to get that valuable black type against her name and hopefully there will be a bit of improvement to come for the rest of the season.”
