Australian batsmen dig in after Smith falls

England snared the prized wicket of Steven Smith as Australia toiled under the lights in a feisty opening day of the first-ever day-night Ashes Test in Adelaide on Saturday.

It was debutant Craig Overton who claimed the huge scalp of the world's top-rated Test batsman for 40, and his first Test wicket in the 63rd over of a grimly-fought contest between bat and ball. But the Australians, leading the series after a 10-wicket first Test win in Brisbane, only lost four wickets after being sent into bat by Joe Root, the England skipper.

At the close, the home side was on 209 for 4 with Peter Handscomb unbeaten on 36 and Shaun Marsh on 20 before an Adelaide Oval record 55,317 crowd.

Overton angled one in between bat and pad to scatter Smith's stumps to the delight of the England team after the Australian skipper's match-turning unbeaten 141 in Brisbane. The seamer earned kudos as the first bowler to bowl Smith in a Test match in Australia since New Zealand's Trent Boult in November 2015.

Smith, who faced 90 balls, had been contained by England's tight lines, and was at the centre of feisty exchanges with the England fielders.

Usman Khawaja raised his ninth Test half-century and was dropped on 44 by Mark Stoneman before he fell in the over after the dinner break. He shaped to cover drive Anderson only to get an edge to James Vince in the gully for 5.

Root, who became the first England captain since Bob Willis in 1982 to bowl after winning the toss in Adelaide, failed to gain any reward until the 15th over after two rain stoppages. England got the initial breakthrough in the over after tea through a run out.David Warner played Broad into the covers where Moeen Ali fumbled the ball as Cameron Bancroft set off for a run from the non-striker's end. Woakes picked up the ball and hit the stumps from mid-off as Bancroft scrambled to make his ground and was run out in the mix-up for 10.

Woakes captured the vital wicket of Warner for 47 in the 34th over. Warner edged an outswinger to Jonny Bairstow and left the home side 86 for 2 as Smith came to the crease.

Australia has beaten New Zealand and South Africa in the two day-night Tests played at the Adelaide Oval.
