Defender Andrew Considine scored a hat-trick as Aberdeen hammered a dismal Dundee side to ensure Celtic must wait to be crowned Premiership champions.
A win for Dee would have handed the title to Celtic, but their visitors put that prospect to bed in the first half.
A Considine double and goals from Adam Rooney and Kenny McLean had Derek McInnes' men 4-0 up at the break.
Ryan Jack hit the fifth before Niall McGinn tapped home and Considine completed his hat-trick.
Aberdeen are 11 points clear of Rangers in third, while Dundee are eighth.
