9st 7lb

J: Cieren Fallon

T: Jonjo & A J O’Neill

Some creditable efforts this year, including when fourth at Carlisle (1m6f, good) in June, but he's without a Flat win since 2023 and was disappointing when favourite at Lingfield (2m, Polytrack) last month; cheekpieces added.

J: Mr Simon Walker

T: Jonjo & A J O’Neill

Without a Flat win since September 2023, but is now 4lb lower than when third of 14 in a stronger race over C&D in April and drops into 0-70 company for the first time; much respected, especially if allowed his own way in front.

J: Daniel Tudhope

T: Jonjo & A J O’Neill

Without a Flat win since 2023 but was placed in valuable 2m AW handicap in April and didn't run badly when sixth of 12 at Ascot (2m, good) last month; eased in grade here; can go well from the front.

J: Harry Burns

T: Jonjo & A J O’Neill

Can set the pace; twice runner-up at Wolverhampton (1m6f/16.5f) during the winter and a good third of 14 in competitive event at Lingfield (2m, also AW; Tarbat Ness sixth) on Good Friday; turf no problem and he should give a good account.

9st 4lb

J: Kieran Shoemark

T: Jonjo & A J O’Neill

Often a front-runner; 1lb lower than when twice runner-up at Wolverhampton (1m6f/16.5f) during the winter and didn't enjoy much luck when behind a couple of these there last month, but the outside stall won't make things easy.
