"It couldn't be better than to have my first treble at my local course," said the teenager, who lives at Clovenfords.

Mania rode a quickfire double, clinching the afternoon's feature race, before adding his third win of the afternoon in the final race of the card on the Selkirk-trained Political Paddy.

The 7lbs claimer – who only rode his first winner in February – brought home Signalman to justify favouritism in the novices' hurdle, before adding the £10,000 handicap chase on Doc Row.

Both winners are trained at Rosewell, near Dalkeith, by Peter Monteith.

Mania's hat-trick was completed in the concluding Irish Racing Annual handicap hurdle race, where Political Paddy, who had finished third at Hexham just two days earlier, got the better of his rivals.

The six-year-old carries the colours of Susan and Rayson Nixon, who train him under permit in the Ettrick Valley.

Signalman began the Monteith/Mania victory trail when coming home ahead of Sirkeel – trained at Lanholm by James Ewart – to take the Louis Coppola novices' hurdle race.

It was a fitting win for the gelding, who carries the colours of Margaret Coppola, whose husband Dennis sponsored the race in memory of his father, Louis.

Half an hour later Mania and Monteith were back in the winner's enclosure when Doc Row gained the advantage over Irish novice chase victor Zitenka by a short head to claim the Ashleybank Investments Reg Tweedie Novices' handicap chase.

Palomar was an impressive winner of the John Merry beginners' chase.

Given a great ride by stable jockey Davy Condon, the winner was reported to have schooled well at home by trainer Nicky Richards, and jumped fluently for a victorious fencing debut.

Rated 126 over hurdles, Palomar is owned by Sir Robert Ogden.

"What he needs over fences is more experience, and his confidence building up," explained the winning trainer."He's a lovely horse and could be pretty good."

Seven went to post in the opening Lilburn Estate introductory hurdle race, where former Grand National-winning jockey Graham Lee enjoyed a comfortable success on the Ferdy Murphy-trained hurdling debutant Ocky De Neuillac.

"Graham gave him a brilliant ride," said Murphy, whose France-bred six-year-old is on the market.

"He's a horse for the future, a real chaser," he added.

Having been off the course for some time, Issaquah made a victorious return in the Scotdisc handicap hurdle race, pulling away under James Halliday.

It was a great training achievement for Malcolm Jefferson – the mare having not run for more than a year.

"She just got a bit of heat in a leg, so we had to wait with her," said Jefferson.

"She's a lovely mare and James gave her a lovely ride," he added.

Runner-up was Tartan Snow, trained on the outskirts of the town by Selkirk farmer Stuart Coltherd.

King Barry produced a game performance to take the Royal Bank of Scotland PLV handicap chase.
