Maurice Edu and Rangers are now just two wins shy of successfully defending their Scottish Premier League crown after putting away Aberdeen on Wednesday night at Ibrox Stadium in Glasgow.
Edu started and went the distance in the Rangers midfield while compatriot DaMarcus Beasley was an unused substitute against the Dons.
After scoring the lone goal in Rangers' weekend victory over Hamilton, Edu took on the role of playmaker Wednesday night and helped the Light Blues score first in the 24th minute.
The US international stripped an Aberdeen defender of possession and then played a ball off to Steven Davis who tallied the game's first strike.
Edu had been fouled on the play but the referee signaled to play the advantage and Davis did just that by uncorking a stunner that curled into the top right corner from 25 yards out.
Thirteen minutes later Edu was involved on a 50-50 ball when he fouled Aberdeen's Mark Kerr at midfield. Kerr barked about the Californian not receiving a yellow card as play continued without any warnings.
Just several minutes after the break, Edu was brought down to the ground after receiving a forearm to the face by an Aberdeen man. It took a minute before the American rose to his feet but later showed no ill effects from the blow.
Rangers doubled the margin in the 64th minute when Kyle Lafferty made a dashing run down the right side before cutting towards the middle and sending a right-footed shot past the fingertips of Aberdeen goalkeeper Jamie Langfield.
But the Dons would answer three minutes later when a Steven MacLaren cross found a sliding Darren Mackie who pushed both himself and the ball into the Rangers net.
Any thoughts of an Aberdeen comeback were put to rest in the 75th minute. Edu split two defenders with a pass down the left side to Steven Naismith who then earned Rangers a corner kick.
On the subsequent corner kick, Danny Wilson headed the ball back across to Kenny Miller who swung it home from the six-yard line.
Head coach Walter Smith now sees his squad extend their lead in the SPL standings to 13 points.
Rangers will get a deserved weekend off and return to action next Wednesday when they travel to Dundee United.
