After last week's loss at Arbroath - and having taken just two points from the last available nine - St Johnstone needed to get back on track. Partick Thistle's midweek win had seen them go level on points with Saints at the top of the table, but Simo Valakari's side strolled to a well-deserved 4-0 win over Greenock Morton. In doing so, they re-established a three-point cushion at the top of the table and, with Airdrie the next visitors to McDiarmid Park, they have a chance to stretch it.
