JinrO was one of the best non-Korean StarCraft II players in 2010 and the beginning of 2011. He was the first to show that the Europeans are equal to Korean professional gamers. The player reached GSL CodeS semi-finals twice. After that JinrO's performance started to worsen. While his opponents kept on improving, JinrO kept declining. Eventually the Swede became a mediocre European player. In August 2012 he announced his retirement.
