Australia has one hand on the Ashes Trophy, despite an English fightback in a bid to level the series.
The Aussies have so far dominated this match, despite their own uncertain first innings.
After making 179, they went on to bowl out England for 67.
They then put on 246 in their second innings, setting the home side a total of 359 – an England record – to win.
Today, England battled to 156-3 by stumps, thanks to 75 not out from Joe Root and Joe Denly’s 50.
They repelled the constant threat of the Australia attack which featured some impressive bowling from Pat Cummins and Josh Hazlewood.
Australia currently leads the five match series 1-0 after three games.
Should they win this one, they will retain the Ashes, since the series can then only finish as a draw or a win for them (the current holders keep the urn in the case of a drawn series).
If England were to pull off the chase and level the series, it will keep this series alive, and set up two exciting contests to end things off.
