Infallible showed some good form last year as a two-year-old

The John Gosden-trained Infallible has been promoted to favourite for next month's 1,000 Guineas after victory in the Nell Gwyn Stakes at Newmarket.

The filly, who went off at 7-2, was settled at the back by jockey Jimmy Fortune in the early stages.

But when Fortune urged his mount to quicken two furlongs from home she looked impressive as she drew alongside outsider Kylane.

She went on to win by three-and-a-half lengths with Festivale in third.

Gosden said: "She's a nice filly, we took our time with her last year and she's been working nicely this spring.

"She'll come on for the run today, we'd planned to drop her in but she got left behind, they didn't go much of a pace and the experience will have done her good.

"She's a fine filly but she'll have to be damn good to beat the French grey filly (Natagora). Our horse is not that experienced after just two runs and Natagora has to be the one to beat at the moment."
