With one day remaining in the Sydney Test, Australia needs 433 runs to win with ten wickets in hand. It shouldn't be possible. Shouldn't.

But this Test - and indeed many Test matches lately - have been so unusual that it can't be absolutely ruled out.

We've seen an exhilirating four days of batting at the SCG. Australia made 474 in their first innings, yet it wasn't enough to avoid giving Indian captain Ganguly the option of enforcing the follow-on (which, as it happened, he elected not to do).
