Scott Arfield's late strike gave Rangers a crucial 1-0 cinch Premiership win over Livingston at Ibrox.
On a rainy night in Glasgow, Arfield, a second-half replacement for James Sands, converted a Borna Barisic cross as the home side struggled to break down a well-organised West Lothian outfit.
The result kept the champions four points ahead of chasing Celtic, who beat Hearts 2-1 at Tynecastle.
