Andrew Little grabbed his first goal of the season as Rangers took a step closer to retaining the Co-operative Insurance Cup with a 2-0 win over Kilmarnock.
The Northern Irishman - making his second start this term - handed the holders a first half lead after Kilmarnock had an early effort ruled offside.
Steven Naismith then continued his fine form this season when he netted in the second half to put the tie beyond the Ayrshire side.
Kilmarnock posed more of a threat in the opening spell and thought they had taken the lead when they had the ball in the back of the net after just seven minutes.
Alexei Eremenko won a free-kick just outside the box and dusted himself off to play the ball short to Craig Bryson who flighted into the box where Liam Kelly was waiting to nod home but the effort was ruled offside.
Rangers had a decent chance of their own when Gregg Wylde's corner found David Weir at the back post but the skipper was denied the opener when his header was smothered by goalkeeper Cammy Bell.
Ben Gordon then lost possession to Naismith in a dangerous area and he set up Little for the shot only for the Northern Ireland international to fire across goal and well wide of target.
The Rangers pair combined well again and had more luck this time when Naismith nodded on for Little and he sent a superb half-volley into the top corner of the net to hand the holders the advantage with 25 minutes gone.
Rangers left the back of the net bulging after 60 minutes when Wylde's pass was collected by Naismith and he dispatched a low shot past Bell into the bottom corner.
The home side could have pulled a goal back soon after but Kelly could only look on in disbelief as his shot cracked off the upright and the chance was lost.
