Scotland v Tonga: Andy Robinson hands scrum-half Henry Pyrgos first international start for Aberdeen Test The Glasgow No 9 made an instant impact, scoring moments after entering the fray. Rory Lawson returns as replacement scrum-half, having not played since the World Cup loss to Argentina in Wellington, and is joined on the bench by uncapped Inverness-born Bath fly-half Tom Heathcote. Heathcote was drafted into the squad on Monday following the release of Ruaridh Jackson and is the understudy to Greig Laidlaw at No 10. Outside Laidlaw sees a new centre combination, with Matt Scott combining with Evans, while the back three of Tim Visser, Sean Lamont and Stuart Hogg remains unchanged. Alongside Scott Lawson in the front row is Ryan Grant and Euan Murray, with Gray and Kellock behind them and uncapped Edinburgh lock Grant Gilchrist in reserve. Blindside flanker Strokosch is joined in the back-row by captain Kelly Brown and No 8 David Denton, with Barclay a substitute. The defeat saw Scotland fall to 10th in the world rankings ahead of the Dec 3, 2015 World Cup draw. Robinson said: "We will not be among the top eight seeds for the 2015 Rugby World Cup draw, so this weekend I'm looking at giving a number of players an opportunity to put their hand up for selection for next year. This weekend we have to put together an 80-minute performance and build on the positive parts of our games that we showed in the last 30 minutes against South Africa and the second-half against New Zealand. International rugby is about pressure and it's important that you convert your pressure into points and when you are under pressure that you are able to absorb it as opposed to conceding points as cheaply as we have done. Scotland team to face Tonga at Pittodrie: Stuart Hogg; Sean Lamont, Max Evans, Matt Scott, Tim Visser; Greig Laidlaw, Henry Pyrgos; David Denton, Kelly Brown (capt), Alasdair Strokosch; Alastair Kellock, Richie Gray; Euan Murray, Scott Lawson, Ryan Grant. Replacements: Dougie Hall, Kyle Traynor, Geoff Cross, Grant Gilchrist, John Barclay, Rory Lawson, Tom Heathcote, Nick de Luca.
