Duhan van der Merwe led the charge with a double as five-try Scotland overcame another half-time deficit to ensure they headed off to the World Cup on a triumphant note by beating Georgia 33-6 at Murrayfield.For the fourth warm-up match in succession, Gregor Townsend's side trailed at the break after a couple of penalties from stand-off Luka Matkava put the visitors 6-0 up.But as was the case in their previous two home matches against Italy and France, the Scots got a grip of proceedings in the second half and went on to make it three wins in four summer Tests after scores from Van der Merwe, Rory Darge, Kyle Steyn and Jack Dempsey.Georgia, who had won 11 of their previous 12 Tests, made a bright start and they gained the first points of the game in the 12th minute when Matkava kicked a penalty between the posts from 40 metres out after Grant Gilchrist failed to roll away.The slow-starting Scots survived a scare in the 17th minute when Georgia wing Mirian Modebadze tried to get on the end of a kick through and slam down over the line but full-back Ollie Smith got back just in time to avert the danger.The visitors continued in the ascendancy though and they doubled their advantage to six points in the 21st minute when Matkava kicked another penalty.The 6-0 deficit seemed to inject a semblance of urgency into Scotland’s play and they started to become more of a threat as the first half wore on.The hosts thought they had got themselves up and running in the 36th minute when Steyn – added to the starting XV on Friday after Darcy Graham was ruled out with a minor quad strain – forced his way over the line in the right corner but following a TMO review he was deemed to have lost control of the ball before placing it down.The
