4/1

Did well for Grace Harris in 2025 and she has continued the good work this time around, getting off the mark for the year with a game win at Bath last week (5f, good); has a penalty to shoulder but she is well drawn and should make another bold bid.

SR 85 is competitive — each-way claims if conditions suit on the day.

3/1

Still to win a handicap and has been turned over as favourite four times this year; did well to finish second last time (first run under Seamus Cronin) having reared at the start and it's bound to fall right at some point, maybe tonight.

Five 5f turf wins on a variety of ground; fair effort on her reappearance (best of the far-side group) but never threatened at Yarmouth last month; she will be well handicapped when her stable find some form.

SR 66 suggests ability but 14/1 reflects a stiff ask in this field.

More prolific on AW than turf; arrives on the back of a solid third at Lingfield two weeks ago (6f, AW); each-way shout.

Nine-race maiden but he has shown some promise and he wasn't beaten far at Bath 12 days ago (5.7f, firm); 1lb lower today and now tried in cheekpieces.
