Rampant Aberdeen close in on lacklustre Hearts

Aberdeen took a fifth-minute lead through Duk's deflected volley

Aberdeen routed lacklustre Hearts to move to within four points of the Scottish Premiership's third-placed side.

Hearts' defending went from bad to worse with Mattie Pollock nodding the hosts' third before half-time.

Duk and Pollock were denied further goals as Aberdeen climbed above Hibernian into fourth place.

The home side were looking for early encouragement and Hearts' timidity did just that. Graeme Shinnie glided past Barrie McKay to cross and Alex Cochrane only partially cleared with Duk's volley deflecting in off Orestis Kiomourtzoglou.

Aberdeen continued to control possession and Hearts stood off Pollock on the right as the defender crossed for Duk to glance a header past Zander Clark.

The third came from the same side with Leighton Clarkson's delivery met by the stooping figure of Pollock as he nodded past Clark.

Hearts were unrecognisable from the team that has looked so comfortable in third all season and they almost fell four behind when Ylber Ramadani fired wide from a Duk pass.

Visiting manager Robbie Neilson took action, withdrawing Alex Cochrane and sending on Stephen Kingsley and later sent on Alan Forrest for Kiomourtzoglou. Aberdeen, too, made a first-half change following left-back Jonny Hayes' head knock, Hayden Couslon taking over.

Clark had a busy second half with saves to block two Duk shots and a couple of Pollock headers.

Hearts' best chances fell the way of Robert Snodrass and Lawrence Shankland, both of whom had returned to the starting line-up. Snodgrass got into an advanced position only to slip a shot wide and Shankland was denied by Kelle Roos from inside the box.

And a flurry of bookings following Aberdeen's disquiet over a challenge on Duk and a series of substitutions proved only to be distractions as the hosts saw out victory.

Michael Smith had to be replaced by Andy Halliday for Hearts near the end due to a head injury.

Player of the match - Duk

Duk once again gave Aberdeen an attacking spark and his finishing, particularly for the second goal, was on point

Perfect day for Dons, perfect storm for Hearts

The turnaround in Aberdeen's form since the 6-0 defeat at Hibs in late January that ended Jim Goodwin's reign is slowly becoming one of the season's most fascinating narratives.

Four wins out of six later, they are very much in the fight for the coveted third place with interim manager Barry Robson being probed on a weekly basis about his suitability and desire for the job long term.

All he can do is keep getting wins and he is now up to three on the spin.

By contrast, it's three defeats in a row in all competitions for Hearts, with Neilson's side looking like last week's Scottish Cup loss to Celtic had really knocked the stuffing out of them.

The return of top scorer Shankland had little impact with the striker offered precious little service until the second half.

More worryingly for Neilson, though, was how passive his defence were, making it difficult for the visitors to gain a foothold. Hearts are now seven years on from their last win at Pittodrie.

What's next?

Aberdeen resume after the international break away to St Johnstone in the Scottish Premiership on 1 April (15:00 BST), with Hearts away to Kilmarnock at the same time.
