Morton 3-0 Dumbarton

Archie Campbell's hat-trick gave Morton their first win of the season as Dumbarton sustained a fourth consecutive defeat.

The Sons tested the home side early on and Morton goalkeeper Derek Gaston had to be alert to tip Scott Agnew's 30-yard effort past the post.

Morton came into the game when Michael Tidser's drilled 25-yard shot cannoned back off the woodwork.

Campbell broke the deadlock two minutes before the break with a left-foot shot into the bottom right-hand corner.

The striker grabbed his second with a well-placed penalty after Andy Graham had fouled David O'Brien.

Allan Moore's men sealed the points when Campbell found the bottom right-hand corner from 12 yards after 76 minutes.

The striker squandered the chance of a fourth goal when his 89th-minute penalty struck the crossbar.
