Roderick Robert Grant led the Scotland sevens squad for the first time when they started the IRB’s 2008-2009 world circuit with visits to Dubai and George (South Africa): he took over as captain from the injured Scott Forrest.

Roddy started as open-side flanker in all five of Scotland’s matches in the IRB Under 19 World Championship in Dubai in April 2006. Later that year he made his international sevens debut for Scotland in the Dubai tournament which opened the IRB’s 2006-2007 series. He played in six of the tournaments in that series. That season, too, he had his Scotland under-20 debut in the February 2007 match against the English at Bath, and he continued in that team for the game against the French in Bourg-en-Bresse.

In November 2008 he was the Scottish Thistles’ joint-top scorer with 45 points (nine tries) in the Singapore international sevens, and he went on to play in the Scotland squad in the 2008-2009 IRB tournaments in Wellington (New Zealand), San Diego (USA), Hong Kong, Adelaide, Twickenham and Murrayfield as well as the RWC Sevens in Dubai, where he scored four tries in helping Scotland to win the Plate competition. Over the 2008-2009 sevens season he scored 23 tries, and his points tally of 115 was second only to Colin Gregor’s 171.

Roddy also played two games for Scotland A in the IRB Nations Cup success in Bucharest in June 2009. He debut was as a replacement in the win against Russia, and his first start followed four days later in the victory against Uruguay. That same month he signed a professional contact with Edinburgh, and his Scotland A career continued with a replacement appearance in the 38-7 win against Tonga at Netherdale, Galashiels, in November 2009. Grant has since played against both Ireland A and Italy A, and took part in the 2010 IRB Nations Cup, facing Georgia, Namibia and Argentina Jaguars. He started the 25-0 win over USA Eagles at Netherdale that November, and came off the bench during the 32-13 win over Ireland Wolfhounds in January 2011 and the 11-3 success against Italy A the following month.

Rugby runs in Roddy’s family: his grandfather (Bob) and great-uncle (George) were international referees, the latter was also Scotland full back in 1950 and 1951 and manager of the 1977 Lions in New Zealand, and Roddy’s father played for British Universities.
 
Roddy played for Natal Schools in 2004 and 2005 and captained Hilton College’s first XV in 2005 as well as being in Natal Sharks’ high-performance squad. He joined Border Reivers in summer 2006 as an apprentice, and the following January he made his debut for the professional team as a substitute in the Magners League match against Newport Gwent Dragons at Rodney Parade. He was awarded the 2008 John Macphail Scholarship, allowing him to have a summer playing for Auckland University club in New Zealand.

Roddy represented South Africa at water polo at under-15 and under-16 levels.
