Jessica Harrington will bid to become the first female trainer to win the Oaks at Epsom on Friday with Jack Naylor among 11 fillies in the Classic.
Fran Berry rides the horse, whose odds have halved in price during the build-up from about 14-1 to 7-1.
Jockey Ryan Moore will hope for more success on Legatissimo after winning the 1,000 Guineas at Newmarket in May.
Trainer John Gosden has declared Star of Seville and Jazzi Top having saddled Taghrooda to victory 12 months ago.
Jack Naylor finished a promising fourth in last month's Irish 1,000 Guineas and Harrington said: "I thought the Guineas would bring her on and it looks like it has.
"You never know with fillies, it just depends how good they are on the day, but we've beaten a couple of the others before and we're looking forward to it."
Aidan O'Brien, a four-time winner, has three chances of success - Together Forever, Diamondsandrubies and Qualify.
Friday is the first day of the two-day Derby meeting and the Oaks, over a mile-and-a-half, also features Crystal Zvezda, Lady Of Dubai, Al Naamah and Bellajeu.
On Saturday, the 236th staging of the Derby, flat racing's premier Classic, sees jockey Frankie Dettori in line-up for the first time since 2010 on favourite Golden Horn.
