Pakistan’s 19-year-old debutant pacer Musa Khan followed in fellow rookie pacer Naseem Shah’s footsteps, after his maiden Test wicket was ruled out due to a no-ball.

Musa overstepped the line on the first ball of the 95th over of the innings and was consequently deprived of his first Test wicket, after Australian opener David Warner slashed at one outside his off-stump — which was taken easily at gully region by fielder Babar Azam. The right-hander was on 226 runs at the point and has looked in sublime form throughout the innings.

Warner hit only the second Test double century of his career on Saturday, punishing poor bowling from a Pakistan attack that rarely threatened him.

The 33-year-old, playing in his 81st Test, began day two of the day-night second Test in Adelaide on 166 and wasted little time in racing to 200.

He reached the mark off 260 balls with a single from Shaheen Afridi, clattering 23 fours along the way.

Warner had been ably supported throughout his innings by Marnus Labuschagne, who was bowled by Afridi for 162 just minutes before he reached the milestone.

Warner's highest Test score is 253 against New Zealand at Perth in 2015.

The opener's heroics in Adelaide followed his 154 in the first Test at Brisbane last week — his first Test century since a year-long ban for ball-tampering.

It has been a big turnaround for the former Australian vice-captain, who managed just 95 runs in 10 innings during this year's Ashes series in England.
