Rampant Hearts took a big step towards finishing third in the Scottish Premiership as they thrashed beleaguered Aberdeen 5-0 with a four-goal first-half blitz at Tynecastle.
Goals from Michael Smith, Lawrence Shankland and Josh Ginnelly, after Graham Shinnie's own-goal, gave the hosts a commanding half-time lead with Cammy Devlin scoring after the break to seal the Jambos' biggest top-flight victory in seven years.
It took Hearts - now unbeaten in eight games - seven points clear of fourth-placed Livingston and nine points ahead of the Dons, widely predicted to be their main rivals for third place.

Boss Robbie Neilson made one change to the side that started last Friday's 1-0 win over St Mirren as Devlin replaced Andy Halliday, who dropped out following a head knock.
Aberdeen manager Jim Goodwin was forced into two alterations to the team that started Sunday's Viaplay Cup semi-final extra-time defeat by Rangers as injured goalkeeper Kelle Roos and suspended captain Anthony Stewart were replaced by Joe Lewis and Jonny Hayes.
The Dons had the first attempt of the match in the eighth minute when Ylber Ramadani seized on a loose pass from Robert Snodgrass and powered forward towards the edge of the Hearts box but his low shot was pushed behind for a corner by Zander Clark.
The Jambos made the breakthrough in the 15th minute when a long throw from James Hill sparked panic among the Aberdeen defenders and the ball bobbled off Shinnie under pressure from Ginnelly and past a helpless Joe Lewis.
And they doubled their lead in the 28th minute when Toby Sibbick's diagonal pass out to the right found Smith and the wing-back took a lovely touch before guiding a left-footed shot beyond the exposed Lewis from just inside the box.
The Jambos' tails were up and they went close to a third in the 33rd minute when Barrie McKay curled just wide from the edge of the box.
Five minutes later, the hosts did make it three when Shankland slotted home his 19th goal of the season from the penalty spot after Liam Scales was deemed - following a VAR review - to have handled from a Snodgrass corner.
Luis Lopes had a great chance to give Aberdeen hope two minutes before the break but Sibbick got back to make a vital challenge just as the attacker was about to pull the trigger inside the box.
Incredibly Hearts still had time to add a fourth before the break as Ginnelly nipped in at the near post to clip the ball beyond Lewis after some superb build-up play by Smith and Shankland on the right.
Seven minutes after the break Shankland almost notched again but he flicked a Ginnelly cross against the near post from close range.
The Dons had started the second half brightly but any hopes they had of kick-starting a fightback were killed off in the 62nd minute when Devlin drilled in from the edge of the box after being set up by Shankland.
Goodwin: I'm embarrassed and humiliated
Aberdeen boss Jim Goodwin said there was "a lot of soul searching to be done" as he apologised to the fans for their 5-0 defeat at Hearts:
"Defensively we were shocking, that's the bottom line. I didn't think there was a great deal between the two teams at 0-0. Hearts were rarely in and around our penalty box.
"They get one opportunity to throw a long throw into the box. We don't defend it properly and even at that point I thought the game was toing and froing. The second goal is a killer and we've got a mountain to climb.
"I'm really embarrassed and humiliated to be standing here after my team have been turned over in the way they have tonight.
"Our away record is abysmal. The goals we've conceded away from home is nothing short of embarrassing and I can only apologise to them [the Aberdeen fans].
"There's a lot of analysis we need to do on tonight's performance. Defensively we've been terrible tonight. I think Hearts have only had six shots on goal and scored five of them. There's a lot of soul-searching to be done tonight and tomorrow. We need to get things sorted."
Neilson: The complete performance
Hearts manager Robbie Neilson was delighted with his team's complete performance in their 5-0 demolition of Aberdeen:
"It's what we're striving for. Throughout this season we've hit that level periodically through the campaign but generally for 30 minutes, 45 minutes, 60 minutes. We managed to do it for the whole game tonight and thankfully we got the three points for it."
What's next?
The attention now turns to the fourth round of the Scottish Cup this weekend.
Hearts host Edinburgh rivals Hibs on Sunday. That match kicks off at 2pm.
Aberdeen are away to West of Scotland League side Darvel on 23 January. Kick-off 7.45pm.
