Double-amputee sprinter Oscar Pistorius fell short of the 400 metre qualifying time for the Beijing Olympics despite running a personal best today.

The 21-year-old South African finished third in 46.25 seconds. That is 11 hundredths faster than he ever ran before, but still outside the Olympic qualifying standard of 45.55s.

It was the final chance for Pistorius to impress the South African selectors, but they can still choose to invite him on a six-man roster for the 1,600m relay.

The South African team for the August 8-24 Beijing Games will be named in the coming days.
