Heart of Midlothian's social media department have become increasingly fond of the word 'relentless' of late.

Understandably so. Not only does it make for a catchy hashtag, but it is hard to think of a more fitting adjective to describe their march to the Championship title.

The capital club's remarkable consistency has ensured they will win promotion back to the top flight at the first time of asking. That much is a foregone conclusion, regardless of how many well-drilled players insist they "are taking it one game at a time".

Following Saturday's 4-0 win over Dumbarton - secured thanks to strikes from Osman Sow, Danny Wilson and a Billy King brace - they require just three more wins to confirm the inevitable.

A more intriguing proposition is just how many records Robbie Neilson's side will break prior to ascending back to the top-flight.

Hearts require just 18 more points to register the highest points tally in the history of the second tier, beating Hibs' league-winning total of 89 under Alex McLeish in 1999.

Their current goal rate of 2.66 goals per game also puts them on course to be the first side to hit three figures in the 'goals for' column since Airdrieonians in 1974. #Relentless, indeed.

"When we were struggling last season, I never saw a league campaign like this coming," said King. "I didn't think we would be as dominant as this and it is a joy to be a part of.

"It's really exciting to be part of team like this as an attacking player. We are lucky enough to be finding the net regularly at the moment which is really enjoyable for ourselves and the fans.

"The manager has instilled a real desire to score goals and keep pushing until the final whistle, which you could see Saturday. We are also keeping clean sheets and have have struck a good balance."

Emotional scenes preceded kick-off at Tynecastle at the weekend, as the club and its supporters said a poignant farewell to Dave Mackay, widely regarded as the greatest ever Jambo.

A minute's silence was impeccably observed for the man who drove Hearts to the league title, a Scottish Cup triumph and two successful League Cup campaigns, while fellow Hearts icons such as Freddie Glidden, Gordon Marshall, Jimmy Murray and John Robertson lined the pitch.

"It meant a lot to me to feature in a really emotional day for the club," added king, a boyhood Hearts fan. "It was important we got the right result. It was a good day all round."

In truth, the football felt somewhat secondary, which perhaps goes some way to explaining a rather sluggish first-half display from the hosts. Hearts struggled to find top gear - despite striking the woodwork twice through Jamie Walker and Osman Sow - and took until the 53rd-minute to break the deadlock.

Sam Nicholson dropped a looping corner kick into the box and Rogers fumbled his catch under pressure from Sow and Genero Zeefuik, allowing the towering Swede to smash home the loose ball. Dumbarton's claims for a foul on their Ireland under-21 stopper fell on the deaf ears of ref John Beaton.

Hearts doubled their lead when captain Danny Wilson powered home a cross from Billy King, before the young forward took centre-stage himself with a wonderful mazy run and low shot past Rogers to make it three.

King added further gloss to the score-line after 89 minutes, cutting in from the right flank, surging into the box and firing a ferocious shot into the net.

"I can't fault the boys for effort," said Dumbarton manager Ian Murray. "We played Hibs the previous week and lost 3-0 and the performance compared to Saturday was just night and day."
