Evans, who is beginning to hit a rich vein of form ahead of the RBS 6 Nations, grabbed a late try put the capital city side in a commanding position.

The 27-year-old will be desperate to regain his Scotland place from Northampton’s Joe Ansbro, whose selection for the final autumn international with Samoa left Evans benched on his return from a shoulder injury sustained two weeks earlier against New Zealand.

DTH van der Merwe and Hefin O'Hare also touched down against Rob Moffat’s men, whose points all came from the boot of David Blair.

Another win would secure Sean Lineen’s team a second double of the season over their rivals and Evans believes the tie is theirs to throw away.

"What we said in the changing room after the game was that there was not much to fear from their side," said Evans.

"It's about sorting ourselves out. We gave them a lot of ball - all of their points came through penalties.

"Apart from one good set play they did from a centre scrum, they never really looked like they were going to score a try.

“I always thought if we could get some position in their half we could do some damage and come away with points, but when they were in our half it was a similar thing as we kept giving away penalties.

“We have to lift the aggression even more in the next game.

“The main word we used going into the game at Firhill was 'relentless' and that's what we have to continue doing over the next few days and into the next game."
