A review of Saturday's action in the Clydesdale Bank Scottish Premier League, including Celtic's win over Hibernian..
Midfielder Kris Commons, who shrugged off a nasty ankle injury to make the game, drove the home side into the lead in the 14th minute and then grabbed a poacher's second the 51st minute before defender Mikael Lustig grabbed the third just after the hour mark.
With closest challengers Motherwell drawing 2-2 at home with St Mirren it means Celtic, with five games remaining after the split, go 15 points clear with a massive goal advantage and while there is no doubt about the destination of the title, Hoops fans will have to wait a bit longer before it is official.
At Fir Park, James McFadden added to his collection of spectacular goals to rescue a deserved point for Motherwell which edges them closer to a European spot.
The Scotland international curled home a free-kick with five minutes left after St Mirren had come from behind to take the lead.
Conor Newton's long-range strike had cancelled out Michael Higdon's 23rd goal of the season and Lewis Guy struck in the 75th minute after Motherwell had come close on numerous occasions in the second half.
But McFadden the final say to ensure Motherwell finished the weekend as they started it - three points clear of Inverness in second place and eight points ahead of the chasing pack in the race for a Europa League slot.
Former Rugby Park playmaker Gary Harkins returned to Ayrshire for the first time since his move to Dens Park but made himself most unwelcome with a goal in either half.
Kris Boyd had levelled just four minutes before Harkins' decisive second to extend his record-breaking tally of SPL goals to 166, but just as they looked set to sneak through on goal difference, Rory Boulding's last-gasp winner for Dundee United in a 1-0 victory against Aberdeen saw the Tannadice men snatch Killie's place in the top half of the table.
The eventual outcome also meant a disappointing end to Aberdeen boss Craig Brown's 36-year managerial career as he now steps aside for Derek McInnes to take over the reins at Pittodrie.
The visitors had been leading 2-1 going into the last quarter of an hour with a double from Steffen Wohlfarth coming each side of Michael Ngoo's 49th minute equaliser.
Substitute Jason Holt equalised for the hosts on 79 minutes before an Evangelos Oikonomou own goal gave them the lead 60 seconds later. Ngoo then completed the goal flurry in the 84th minute .
The defeat sends County to their third successive defeat in the SPL and keeps them trailing rivals Inverness by six points in the race for Europe.
