Sally Brown finished third in the 100m to secure her second bronze medal at the European Championships in the Netherlands on Tuesday.
The Ballykelly teenager also finished third in the 200m on Monday.
Brown has qualified to compete in the 100m and 200m events at the Paralympic Games In London later this year.
She was among the 10 contenders for the 2011 BBC Young Sports Personality of the Year award and carried the Olympic torch on its visit to Northern Ireland.
The official Great Britain and Northern Ireland team for the Paralympics will be finalised on 10 July.
For 17-year-old Brown, the Dutch championships represented her first competitive action since suffering a double stress fracture.
