London - Brazil's Alan Fonteles Cardoso Oliveira upset defending champion Oscar Pistorius to win the men's 200m title at the London Paralympic Games on Sunday.

South African Pistorius streaked into an early lead and was almost 10m ahead as the athletes came into the closing straight.

The Brazilian, however, struck back in the closing stages to eat up the ground and surge past Pistorius in the final few metres.

Oliveira finished with a time of 21.45 seconds, seven tenths of a second ahead of Pistorius, with American Blake Leeper in third place. - Reuters
