Dundee striker Joe Westley says their 1-0 win over St Mirren was "massive" but insists no one will think their Premiership status is secure until it is "mathematically done". Westley's early strike proved decisive as they edged out the Paisley side at Dens Park on Saturday. The result leaves Dundee six points clear of the relegation play-off spot, which is now occupied by St Mirren following Kilmarnock's win against Dundee United.
