O'Brien hoping Tenebrism will stay as he bids to extend 1,000 Guineas dominance

Aidan O'Brien has won the 1,000 Guineas five times in the last six years and seven times overall. Nobody else currently training has taken it more than twice. Tenebrism looks the one to beat after success in Group 1 Cheveley Park Stakes over six furlongs here in September. Tuesday won her maiden at Naas last month. O’Brien didn't think Tuesday would be ready to run here after she won a maiden race at the same venue.

Discoveries is a well-bred filly. She is the sister to Alpha Centauri, a superstar three-year-old for Jessica Harrington and the Niarchos family in 2018. Discoveries beat Agartha in the top-level Moyglare Stud Stakes at the Curragh. Minding and Love have gone on from victories in MoyGlare to land the Guineas the following season.

Cachet is the first horse trained by George Boughey in 2019. She was beaten by Inspiral in the Fillies' Mile last autumn. Caccheth finished fourth in Breeders' Cup Juvenile Fillie Turf at Del Mar next time out. She won the Nell Gwyn Stakes over seven furlongs at the course last month.

O'Brien hoping Tenebrism will stay as he bids to extend 1,000 Guineas dominance. David Egan, rider of Ameynah, is confident of beating the winner in the Nell Gwyn. Francis Graffard, trainer of Malavath, couldn't have the filly in better form. Charlie Appleby, the trainer, thinks Wild Beauty has a live chance. Ralph Beckett, Prosperous Voyage's trainer is looking forward to running her. Andre Fabre, Zellie's, has worked well and is in good shape.
