Killie made it 4 on the trot, 9 points out of 9, and a third straight clean-sheet for 2005.

Kris Boyd grabbed a double as Kilmarnock recorded their second win in a week over Motherwell.

The Scotland Under-21 striker stroked the ball home after only 57 seconds on a day when the visitors missed a host of chances of their own.

Steven Naismith squandered a glorious opportunity for Killie before setting up Boyd to fire in the second.

McDonald was the main culprit for Well, missing a couple of chances as Killie repeated their Scottish Cup win from last week.

Simon Ford had replaced injured Gordon Greer in the Kilmarnock defence, while Marc Fitzpatrick and William Kinniburgh were relegated to the Well bench in favour of David Partridge and Paul Quinn.

Motherwell found themselves trailing with just 57 seconds on the clock.

The home fans didn’t have long to wait for the opening goal, 60 seconds to be precise. Freddie Dindeleux, making his 200th appearance for Killie, started the move with a long ball out of defence. Gary McDonald’s a cross from the right was missed by Gordon Marshall allowing Colin Nish to nod the ball back across goal to Boyd who had the simplest of tap-ins.

Motherwell almost equalised seconds later when goalkeeper Alan Combe spilled the ball and David Clarkson's strike cannoned off the body of Ford.

Combe turned a 25-yard Scott McDonald drive past the post.

Defender Martyn Corrigan burst through but fired wide of the Killie goal.

Stephen Craigan managed to get himself on the end of a corner and his header looked goalbound until Freddie Dindeleux nodded off the Killie line at the near post.

Killie's Steven Naismith provided the worst miss of the first half, falling over when he had only the goalkeeper to beat.

However, the forward made amends by setting up Kris Boyd for his second goal, the striker turning Craigan before firing home on the stroke of half-time.  (right)

McDonald raced past David Lilley into the box early in the second half only to see the effort creep past the post.

Motherwell goalkeeper Gordon Marshall managed to tip Danny Invincibile's point-blank shot over the crossbar.

McDonald set up Clarkson who successfully took the ball past the Killie goalkeeper but was less successful in finding the back of the net.

Danny Invincibile and Scott McDonald had a rare opportunity to impress the Australian national coach Frank Farina who was watching in the main stand and just before the hour mark both players were involved in the action with contrasting fortunes. The Motherwell striker was the first to impress showing the Killie defenders a clean pair of heels, but once again he couldn’t finish and his final shot drifted harmlessly wide. His compatriot Invincible was more convincing minutes later latching on to a clearance ten yards out before unleashing a shot which Marshall tipped over the bar at full stretch.
