Clarcam left his below-par performance in the Arkle at Cheltenham behind when running out an impressive winner of the One Magnificent City Manifesto Novices' Chase at Aintree.
Sent into the lead by Ruby Walsh after the fourth fence, the Gordon Elliott-trained five-year-old put in a foot-perfect round of jumping in the two-and-a-half-mile contest.
Favourite Josses Hill tried to match Clarcam, but did his chances no good by continually jumping right and was soon beaten off after the second-last.
On the run down to the final fence, the strong-travelling Vibrato Valtat emerged as a serious threat, but the 5-1 winner found plenty when called on for on a maximum effort, and another bold jump at the last put the race to bed as he eventually scored by four lengths from the Paul Nicholls-trained runner.
Meanwhile, All Yours came with a sustained late run to land a surprise victory in the Betfred Anniversary 4-Y-O Juvenile Hurdle at Aintree.
The field were taken along in the early stages by Starchitect and Ruby Walsh, with Irish raider Hostile Fire keeping close attention.
As the latter was burnt off rounding the home turn, Devilment, who had raced handily, moved up on the hind quarters of the long-time leader at the third-last.
It was at this point that 4-6 favourite Hargam, despite having travelled sweetly, came under a strong ride from Tony McCoy.
Over the last Devilment moved into a clear advantage but was soon tracked through by Bristol De Mai, with Hargam well and truly treading water.
A mistake at the last did not halt the momentum of Devilment with him battling on alongside Bristol De Mai, but although the pair looked to have the race between them, a power-packed Sam Twiston-Davies ensured the Paul Nicholls-trained 16-1 shot sailed past the pair of them.
The winner went on to score by three-quarters of a length from Devilment, with Bristol De Mai a further half-length away in third.
On The Fringe (above left) gave Nina Carberry a dream outing over the Grand National fences when posting a stylish success in the Crabbie's Fox Hunters' Chase at Aintree.
In a race which saw a fair number of casualties, an ice-cool Carberry delivered the well-supported 5-2 favourite with a perfectly-timed run to become the first horse since Double Silk back in 1993 to win both the Cheltenham and Aintree hunter chases in the same season.
Any chance of a repeat victory for Warne and Sam Waley-Cohen ended early on with the pair coming to grief at the first, while a fence later Tartan Snow departed.
The field were taken along early on by Bound For Glory, with both Ockey De Neulliac and Pacha Du Polder kept close to the leader's heels.
With little change through the majority of the race, it was not until the run to the penultimate fence where Pacha Du Polder moved into a clear lead.
Although in the driving seat, the Paul Nicholls-trained eight-year-old was merely a sitting duck for Enda Bolger's strong-travelling On The Fringe, who in a matter of strides after the last moved up on his shoulders before taking matters up around the elbow and going on to score by three and three-quarter lengths.
