Steve Smith survived a run-out chance and Australia took a 12-run first-innings lead at stumps on Friday in the final Ashes test which England must win to level the series.
Smith came desperately close to being run out at the Oval by substitute fielder George Ealham in a pivotal moment on the second day.
Australia was 295 all out off the final ball of the day as Smith rode his luck to top-score with 71 following a scare just after tea.
