The victory of Josses Hill initiated a superb treble for the formidable team of Nicky Henderson and Barry Geraghty at the Aintree Festival, with Ma Filleule securing the second leg of the hat-trick with a spring-heeled display in the Crabbie's Supporting Everton In The Community Topham Chase.
Having chased home Holywell at Cheltenham, the 9-1 shot brought strong form to the race and jumped impeccably over the Grand National fences on her way to an eight-length triumph over Bennys Mist.
Eastlake and Tatenen finished third and fourth respectively, with favourite Double Ross fifth.
Henderson said: "She enjoyed that. I hoped she would. She seemed very good at home."
Henderson went on to suggest Ma Filleule might emulate last year's winner Triolo D'Alene and return for the National next year.
"The idea in the Topham is to see if you can look at the National the next year," he said.
An excellent afternoon's work was complete for the Seven Barrows outfit when Beat That (6-1) slammed his opponents in the Grade One Doom Bar Sefton Novices' Hurdle.
Clondaw Kaempfer (10-1) came out on top in a thrilling climax to the Alder Hey Children's Charity Handicap Hurdle for trainer Donald McCain and jockey Wayne Hutchinson, getting up to beat Caid Du Berlais by a neck.
McCain said: "He's magic. It's just been taking time for the penny to drop, but he has loads of ability."
"We've always thought plenty of him and today you see he has a bit of growing up to do.
"He might be helped by fences but what we do now I don't know as he couldn't win his point."
Alan King's 25-1 shot Avispa was a surprise winner of the concluding Concerto Group Mares' Standard Open National Hunt Flat Race under Robert Thornton.
King said: "She's very good and I actually thought she'd win at Sandown (last time), but she got stuck in the really holding ground, travelled well but didn't get home.
"Her work at home has always been really good.”
