Stander went to school in Queenstown, where he earned a few call-ups to the youth sides of the Border Bulldogs. At primary school level, he was selected for the Border side that played at the 2007 Under-13 Craven Week competition. At high school level, he played for Queen's College and represented Border at the Under-16 Grant Khomo Week in 2010 and the Under-18 Craven Week in 2011. He was also eligible to play at the 2012 Craven Week, but was not picked as he had agreed to join the Pretoria-based Blue Bulls[2] and fell foul of a newly-adopted Border Rugby Football Union policy of not picking players for their Craven Week squad that already signed contracts with other unions.
Stander also played for the Blue Bulls U21 side in the 2014 Under-21 Provincial Championship. His game against the Border U21 turned out to be a memorable one as he scored two tries and kicked twelve conversions for a personal points haul of 34 points as the Blue Bulls recorded a 143–0 win.[4]
Blue Bulls
His first class career started in the 2014 Vodacom Cup. After being an unused substitute in their matches against Griquas[5] and the Pumas,[6] he made his debut for the Blue Bulls in their match against the Leopards XV in Leeudoringstad, kicking two conversions in the match as they secured a 30–26 victory.[7] Further appearances followed in their matches against the Falcons[8] and the Griffons[9] before Stander scored his first career try against the Limpopo Blue Bulls, also slotting five conversions in the match despite only coming off the bench in the second half.[10]
