O'Brien hails 'massive engine' of his little beauty September

Punching above your weight does not always pay off, but September showed size is not everything when picking up smartly under Ryan Moore to deliver her master trainer Aidan O'Brien a 60th Royal Ascot victory.

The Ballydoyle ace, celebrating his fifth winner of a week that has not all gone to plan after defeats for Churchill and Order Of St George, was left purring by the performance of the juvenile, who was making it two from two having hacked up in her maiden at Leopardstown with Seamie Heffernan on board this month.

She is bred to be good, being by prolific Japanese champion Deep Impact out of Peeping Fawn, whose four Group 1s for O'Brien included the Irish Oaks in 2007.

"I'm delighted with her," O'Brien said. "She's out of Peeping Fawn by Deep Impact so she's bred absolutely in the purple and has a massive engine, is a great traveller and can quick really well. She's not very big, but she thinks she is and has a big personality and big presence.

"She believes she's big and is confident in herself. She was very cool when I was tacking her up; in that zone good horses can be in."

O'Brien, now alongside Paul Cole with four Cheshams on his CV, added: "She could be anything. Seamie was really happy with her at Leopardstown and when I was tacking her up [my son] Joseph said she was the first first-time-out two-year-old winner we've had this year."

O'Brien, who quickly had his 61st Royal Ascot winner when Idaho won the Hardwicke, added: "She's very exciting."

September was cut to either a 5-1 or 6-1 chance (from 14 generally) for the Qipco 1,000 Guineas and can be backed at 10-1 with bet365 or Betfair Sportsbook (from 25) for the Investec Oaks.

"She could take in the Debutante on the way to the Moyglare and you imagine she'll stay much further next year, but she coped well enough with seven furlongs today," O'Brien added after seeing September repel the front-running Nyaleti, who finished second, with Masar third.

"She's bred to stay very well, but we were thinking of the Albany over six until Ryan said he wanted her for this.

"If she finishes off at a mile this year we'll see about next year."

Moore, now on three Chesham winners and 48 at the royal meeting, was also impressed.

He said: "It rode like a good race and she stayed on strongly. She had her first race only a couple of weeks ago and has a lot of quality."
