J: Harry Burns

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.

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.

J: Cieren Fallon

T: Jonjo & A J O’Neill

Front-runner who was well beaten over hurdles last time but had previously twice finished runner-up here (1m6f/16.5f); may be happier back in this sphere, but likely to face competition for the lead.

J: Kevin Brogan

T: Jonjo & A J O’Neill

Won four-runner Kempton novice (2m5f, good) on last season's hurdling debut but the form looks dubious (leaders went off far too quickly) and he was well beaten in his first two handicap hurdles (2m7f/2m4f); reverts to hurdling after two good AW seconds this winter but still needs to prove he can cope with his current mark.

9st 7lb

J: Ray Dawson

T: Jonjo & A J O’Neill

Out of form on his last three starts in the spring; however, he goes well fresh so a break may have helped, and he's now 10lb lower than when third at Southwell (2m, AW) in February; interesting contender.
