Nakheel charges in to seize the riches from Park Hill.
Owen Burrows and Jim Crowley team up for Doncaster strike.
At the Doncaster Betfred Park Hill Fillies' Stakes, the unexposed Nakheel made the most of her weight allowance to hold off the reliable Night Sparkle.
The three-year-old, who is trained by Owen Burrows, was unattached at the beginning of the season and has gradually gained experience in Pattern Company.
At York's Ebor meeting, she finished third in the Galtres Stakes, behind Scenic by four lengths, but she appeared considerably more comfortable going the extra two miles.
It didn't matter that Jim Crowley decided to challenge from the inside, as he had been rejected in the last race.
After Sumo Sam, the winner of last year, started to backpedal, Ryan Moore appeared to have the upper hand on Grateful for a brief while, but Grateful was found wanting when stamina was at a premium.
Wearing cheekpieces for the first time, Nakheel (10-1) made her move and had enough in her locker to hold off Night Sparkle by 1.5 lengths.
