Hooker Gregor Hiddleston scored a crucial try on debut as Scotland finished strongly to beat Argentina 47-38 Saturday in the first round of rugby's Nations Championship. Scotland was under severe pressure with a two point lead and a man in the sin bin with 15 minutes remaining. Hiddleston's try gave Scotland breathing space and it finished powerfully with a try to Kyle Rowe to win by seven tries to five and post its highest-ever score against Argentina.
