Emmet Mullins pulled off another masterstroke as Slate Lane ran away with the £150,000 Betfair “Serial Winners” Stayers’ Handicap Hurdle at Haydock.

Owned by Paul Byrnes, the man behind so many of Mullins’ breakthrough horses, Slate Lane was winning for the fourth time in succession.

Donagh Meyler always looked in complete control on the 11-4 favourite and he survived a messy jump at the last to win in style.

What would have made the result all the more satisfying for the trainer was that back in second, a length and a half away, was Fine Margin, trained by his uncle and champion trainer, Willie.

There was some concern after the race, however, as the winner returned with a nasty looking cut on his leg.

Before walking back to the stable yard to see to the injury Mullins said: “He’s won four in a row now so it’s great, it’s all come together.

“To be honest since he crossed the line at Cartmel in a maiden hurdle this was the plan and it was about getting him here on a reasonable mark and it’s come off.

“Everything went well. I thought there might not be much pace so I said to Donagh to line up wide and see how it unfolds and he was wise to it, he did the right thing letting him off.

“He’s very straightforward and as long as he keeps winning we’re happy enough.”

Byrne added: “It’s unbelievable, I’m delighted. He’s a great horse to win four in a row.

“Donagh was brilliant on him, he’s a cracking rider and I can’t understand why he doesn’t get more opportunities at home. He’s been very lucky for us.

“This was the plan. When you have a three-miler this was the one you are aiming for because there’s nothing else worth this much, it’s not like with a two-miler.

“I don’t think we’ll qualify for the Pertemps, but he is still a novice, whether he’s that good I don’t know.

“The cut is a little bit worrying, Emmet has followed the horse down and he doesn’t normally do that. It’s a bit concerning, Emmet didn’t like it.”

Kamsinas built on the promise of his previous outing when landing the Betfair Racing Podcasts Newton Novices’ Hurdle.

Trained by Fergal O’Brien, the six-year-old had gone close in Grade Two company at Cheltenham behind Neil King’s Lookaway and when the winner ran a big race in the Greatwood Hurdle afterwards, O’Brien knew he had a nice youngster on his hands.

He was taking on a couple of well-regarded types in Henry Daly’s Bowenspark and the Lucinda Russell-trained Primoz, but they could not live with Kamsinas (16-5) in the straight.

Oliver Greenall and Josh Guerriero’s Making Headway tried to make a race of it, but still went down by a length and a quarter behind Paddy Brennan on the winner.

O’Brien said: “We were very hopeful – I’m never confident – as he’d been working well and was very unlucky at Cheltenham when he got stopped in his run.

“That form was franked by the winner and what I loved about him there was he threw himself over the last showing a great will to win.

“I’m delighted with him, he’s a super little horse. We’ll all sit and have a chat about what next but we thought something like this was in him. We need these days.

“It’s a long road to Cheltenham in March and hopefully there’ll be a lot of races before then. I think he’ll get further and he’s already shown he handles Cheltenham.”

Dan Skelton hopes the handicapper does not get too carried away after Real Stone coasted to victory in the betting.betfair.com Handicap Chase.

When his two main market rivals, Cheddleton and Pay The Piper, dropped away, the 15-8 favourite coasted to a 20-length win under Harry Skelton.

Skelton said: “The first thing I have to say is that I hope the other two are OK because they clearly haven’t given their true running, they are good horses on their day.

“When you’ve been having a bit of a run like we have, when there’s nothing wrong with them but winners are not exactly flowing, it’s nice to enjoy one like that.

“We’ll go quietly with him, he’s not had loads of racing and he probably has to go left-handed which rules out those Ascot races, but we hope to end up in something like the Red Rum (at Aintree).”

Stuart Crawford ran two in the Best Odds On The Betfair Exchange Handicap Hurdle, both owned by Simon Munir and Isaac Souede, and with Daryl Jacob unable to get down to 10st 3lb on Park Annonciade it was left to Ben Bromley to do the steering.

Son of the racing manager of the owners, Anthony Bromley, his 5lb allowance took his weight down even lower, the 3-1 joint-favourite beating Stainsby Girl by two and three-quarter lengths.

“I’m delighted to ride a winner on a big day like this, it’s huge for me,” said Bromley.

“I’m also delighted for Stuart, he’s a great trainer and is a big part of Simon and Isaac’s team, who I must also thank for the opportunities they keep giving me.”
