Billy Kirkwood’s side made it two wins from two outings in the competition thanks to a clinical display that delighted their coach.
Kirkwood’s side cruised to a 4-0 lead in the first half with a dominant display to follow up last month’s victory over Partick Thistle.
They weren’t satisfied with that however as they then went on to improve their display in the second period as the goals simply kept coming.
A hat-trick for Glody N’Tumba put him head of the scoring stakes with single strikes coming from Adam Wilson, Dylan Dykes, Ryan Hardie, Junior Ogen, Ryan Sinnamon, Jamie Mills and Ally Berry.
The home side were out of the blocks quickly with Hardie setting up Wilson for the opener after just six minutes.
Having picked the wrong option in shooting just minutes earlier, this time Hardie slotted in Wilson who finished coolly.
The appetite for more was clear and when N’Tumba found a yard of space in the box he rifled an effort low in to the corner after just 10 minutes.
The powerful striker made it three for Rangers just four minutes later when he latched on to Tom Walsh’s fine through ball to slot the ball under Cameron Cairney in the visitors’ goal.
Walsh might have set up another just before the 20 minute mark but his tricky wing play on the left was a little overdone and in the end he could only force a corner.
The home side were clearly on top and after Andy McKinnon had stung Cairney’s palms with another effort on 25 minutes they extended their lead before the half hour mark.
Fullback Mills was released down the left flank and he showed great energy and pace to make space for the cross.
When he delivered it was with great pace and accuracy and left Dykes with the task of glancing the ball toward goal with his head to extend the lead to four goals.
Not happy to rest on their laurels, Kirkwood sent his side out looking for the same attitude and approach in the second half.
He was to get exactly that as N’Tumba latched on to McKinnon’s cross in the first minute of the second period to get the scoring going again and complete his hat-trick.
That signalled a chance for Kirkwood to integrate some of his younger players and it was sub Ogen that set up the sixth on the hour mark.
His neat footwork and through ball set Hardie free to round the keeper and slot in to the empty net.
Ogen then turned scorer as he collected the ball from Mills and also danced his way round Cairney in the visitors’ goal to give a simple finish after 65 minutes.
The pick of the bunch though came from right back Ryan Sinnamon who did well to get forward, cut inside and curl a brilliant effort beyond Cairney with his left foot.
His opposite fullback Mills was keen to get in on the action, but in truth his curled effort to make it 9-0 was more likely a cross aimed for McKinnon.
With eight minutes still to play at that stage it was clear the target was double figures and it was achieved within 60 seconds.
Sub Ally Berry found himself in plenty of space when the ball dropped to him around 12 yards from goal and he fired high in to the net.
Rangers: Kelly; Sinnamon, Brownlie, Pascazio, Mills; Dykes, Walsh (Berry 61), A.Wilson (Ogen 46); Hardie, N’Tumba (McIntyre 55), McKinnon.
