The Australian men's cricketers have their work cut out if they're to somehow turn the tide on day four of the World Test Championship final at Lord's

South Africa are on top, set to resume on 213 for two ... chasing 282 for victory ... and with a dominant third-wicket stand of 143 runs at the wicket.

Aiden Markram's on 102 and captain Temba Bavuma on 65.

But former Black Caps spinner now Australian bowling coach Daniel Vettori still believes - and says they have to break the challenge off into pieces.
