Rangers cut the gap to SPL leaders Celtic to just one point with a 4-0 victory over Hibernian at Ibrox.
The hosts, who were without the ill Nikica Jelavic as he continues to be linked with a move to England, took the lead when captain Steven Davis curled past Mark Brown.
David Healy put his hand up to replace Jelavic as he added the second, tapping into an empty net following a mix-up in the Hibernian defence.
Hibs were reduced to ten men when James McPake was shown a second yellow, shortly before Sone Aluko added a third with a long-range free-kick. Davis completed the scoring in injury time.
