Fair Eva kept her unbeaten record intact with a hugely impressive display in the Princess Margaret Juddmonte Stakes at Ascot.
The daughter of Frankel made a big impression on her racecourse debut at Haydock last month and the subsequent victories of both the second, Nations Alexander, and the third, Miss Infinity, confirmed her place as ante-post favourite for next year's 1000 Guineas.
Roger Charlton's filly was the 4-6 favourite stepped up to Group Three level in the hands of Frankie Dettori and her supporters had few worries throughout the six-furlong heat.
Dettori cut a confident figure in the saddle, with the popular Italian still motionless heading inside the final two furlongs.
Once asked to extend, Fair Eva displayed a sublime change of gear to leave the rest of the field trailing in her wake and she only had to be pushed out to score by four lengths - providing Frankel with his first Pattern-race success as a stallion.
Kilmah (12-1) filled the runner-up spot, just ahead of Dainty Dandy (25-1) in third.
Dettori said: "She's a very, very good filly.
"It took her 50 yards to get into top gear, but once she got into top gear at the furlong marker she put four lengths on the field.
"It's only her second run, so she's a work in progress.
"When the penny dropped she was very exciting."
