Aidan O'Brien's promising filly History put herself in the Irish 1,000 Guineas picture with a win in the Cornelscourt Stakes at Leopardstown.
The well-bred Galileo filly place second on her two starts last Summer but got the job done at Gowran Park in September, with AP O'Brien beating his son Joseph's Clemmie C.
History was a 3/1 chance at Leopardstown for the one miles Group 3 and won well in the end in a keenly fought race.
Ryan Moore got History focused coming off the home turn, stalking 6-4 favourite Agartha and eventually surpassing her, keeping on for a three quarters of a length win. Henry De Bromhead's Honey Girl was back in third.
Coral subsequently cut History to 16-1 from 25-1 for the Cazoo Oaks at Epsom, with O'Brien having an embarassment of riches when it comes to potential Classic glory but the Irish 1000 Guineas is first on the agenda.
"I'm delighted with her, she got plenty of time to come to hand, and we were running her to see whether we go to an Irish Guineas or an Oaks with her," said O'Brien.
"Ryan was very happy and said to go to the Irish Guineas with her, she can do that (Oaks) then after.
"She's highly strung but she's lovely. The second is a good filly and you'd have to be very happy.
"I was hoping she'd run well and was hoping that we'd find out whether to go to the Irish Guineas or Oaks. The way she quickened, you have to give her a chance at the Irish Guineas."
The Irish 1000 Guineas takes place at The Currage racecourse on Sunday, May 22 and goes to post at 15.45. John and Thady Gosden's Inspiral is the current favourite with Aidan O'Brien's Tuesday and the aforementioned History vying to be market leader.
