Dundee have won three of their last four league meetings with St Johnstone (L1), more than their previous 11 beforehand (W2 D3 L6). After their 2-1 win in October, St Johnstone could win away to Dundee twice within a single top-fight season for the first time since 1998-99.

If Ross County take maximum points against St Johnstone, then they could leapfrog both Hearts and St Mirren should results elsewhere prove favourable, though any victory will be built on their defensive solidity given that they have scored the joint-fewest goals in the division along with their hosts.

St Johnstone are unbeaten in five league meetings with Ross County, winning three of those (D2), which is as many as their previous 18 games against the Staggies in the Scottish Premiership beforehand (W3 D10 L5).
