Rangers' woeful record at Pittodrie continued as they were beaten 1-0 by a battling 10-man Aberdeen.
The Dons, who have now only lost once to the Glasgow giants in their last nine visits to the Granite City, took the lead after 17 minutes when Lee Miller reacted smartly to prod home Michael Paton's driven cross for his third goal of the season.
However, Mark McGhee's side were reduced to 10 men on the hour mark when captain Mark Kerr was shown a second yellow for a challenge on Steven Naismith. Rangers threw everything at the Dons until the final whistle but the home side managed to withstand the pressure to earn a hard-fought victory.
The home side also started brightly with Christopher Maguire volleying over the bar followed by a mazy Peter Pawlett run that ended with the teenager's shot being deflected wide for a fruitless corner.
Aberdeen's positive start was rewarded after 17 minutes when Paton twisted past Steven Whittaker to drive a low cross into the box that was prodded home by Miller for his third goal of the season.
Rangers could have restored parity after 26 minutes when Kris Boyd skipped past Richard Foster before unleashing a volleyed shot-cum-cross that was headed over by Kyle Lafferty with the goal gaping.
The away support were screaming for a penalty on the half hour when Whittaker fell under pressure from Maguire but referee Craig Thomson waved play on.
Foster rescued the Reds when he got his body in front of Kris Boyd's goalbound left-footed volley as the visitors were denied an equaliser just before the break.
The Dons had a great opportunity to double their advantage after the break when Sasa Papac was booked for upending the lively Pawlett on the edge of the box. But the Bosnian made amends by clearing Charlie Mulgrew's free-kick, which took a wicked deflection, off the line.
The Dons were reduced to 10 men on the hour when Kerr, who had already been booked for a foul on Naismith after 49 minutes, was given a second yellow for another challenge on the same player. The home side were camped in their own half with little respite in the final stages but held on for a famous victory.
