Two goals by Owen Coyle - both from the penalty spot - led Airdrieonians back to the top of Division One on a night to forget for Clyde.

The Bully Wee were left with 10 men after defender Bryan Smith was sent off after only 13 minutes when he handled Mark Roberts' goalbound shot.

And, from the resultant penalty, Coyle easily scored to give Airdrie the lead.

As Clyde pushed forward, Roberts added a second four minutes later when he dragged the ball across the face of the goal before firing into the net.

Even better was to follow for Airdrie when Jack Ross pushed Lee Gardner inside the penalty area in 26 minutes and Coyle knocked in a third, again from the penalty spot.

Coyle came close to his hat-trick just a minute from the interval with a clever lob that swirled just past the post.

Clyde fought back in the second period, but they rarely troubled the Airdrie defence, though Craig Cranmer came close with a header on the hour mark.

Airdrie: Ferguson, Armstrong, McPherson, Stewart, McManus, James, Gardner, MacFarlane, Coyle, Roberts, Smith
