GLASGOW, Sept 13 (Reuters) - Leaders Rangers came from a goal down to beat Kilmarnock 2-1 in the Scottish Premier League on Saturday and city rivals Celtic beat Motherwell 4-2.
Kilmarnock took a surprise lead after nine minutes when defender Frazer Wright pounced after hesitation from Rangers keeper Allan McGregor and forced the ball home from six metres.
However, Rangers recovered in the second half and levelled when Kris Boyd blasted a 61st minute penalty beyond keeper Alan Combe.
He turned to crash a fierce 15 metre shot past Combe to put Rangers 2-1 ahead on 63 minutes.
Greek striker Georgios Samaras scored twice as Celtic swept to a thrilling 4-2 victory at Motherwell in the Scottish Premier League on Saturday.
The Scottish champions were 3-0 up inside the opening 25 minutes thanks to goals from Shaun Maloney, Samaras and former Motherwell striker Scott McDonald.
Maloney scuffed in a five-metre shot from the left after only five minutes for his first goal since returning to Celtic from Aston Villa last month.
Three minutes later, Samaras burst into the middle of the penalty area and drove a low shot past keeper Graeme Smith for Celtic's second.
McDonald added a third when he ran onto a long throw-in from the right by Mark Wilson to leap and crash a bouncing ball from 10 metres into the top right-hand corner.
Celtic continued to turn the screw and Maloney rattled the Motherwell crossbar with a 20-metre free kick in the 37th minute.
Samaras grabbed his second just before the break, fastening onto a neat, back-heeled pass from McDonald to charge into the area and slip a shot under Smith for 4-0.
Motherwell staged a brief, second-half rally with two goals inside three minutes as John Sutton fired into the bottom right before David Clarkson toe-poked a shot past keeper Artur Boruc.
But Celtic were still heading for a victory which lifted them to 10 points from five games. Rangers, on 10 from four games, play Kilmarnock later on Saturday.
St Mirren won 2-1 at Inverness Caledonian Thistle, Hibernian beat Dundee United 2-1 and Falirk inflicted a 2-1 defeat on Hearts. Hamilton Academical managed a surprise 2-1 win at Aberdeen.
