British teenager Jonnie Peacock defeated Oscar Pistorius' conqueror to reach the 100 metres final with an emphatic heat victory at the Olympic Stadium.
The 19-year-old, who looked relaxed and confident in his blocks, got off to a flying start and came home in 11.08 seconds, equalling the T44 Paralympic record.
It was a baptism of fire for Peacock, who lined up against American world champion Jerome Singleton and Brazilian Alan Fonteles Oliveira, the 200m gold medallist whose blades so incensed Pistorius.
Only the top two advanced along with two fastest losers, but the Cambridgeshire athlete is not the world-record holder with a best of 10.85secs for nothing.
Peacock, who lost his right leg below the knee to meningitis aged five, easily finished ahead of Singleton, who was second in 11.46s.
Oliveira was third in 11.56.
