The world record has been broken twice in the heats of the men's T44 200m.

In the first heat Alan Fonteles Cardoso of Brazil posted a 21.88 after getting off to a terrible start.

Then in heat three Oscar Pistorius showed that he means business by smashing Cardoso's time with a 21.30.

The final is set to be a quick one, with heat two's winner Blake Leeper also dipping under the world record as it stood before the day started. He ran 22.23.
