WATCH: Wasim Akram's reaction over Babar Azam's dismissal in Perth Test

Australia’s all-rounder Mitchell Marsh dismissed Pakistan’s star batter and former captain Babar Azam in the first innings on the third day of the opening Test of the series in Perth on Saturday.

Azam edged one to wicketkeeper Alex Carey after scoring 21 runs in the first session of the day.

Meanwhile, the reaction of legendary Pakistan pacer Wasim Akram has gone viral where he showed mixed reactions.

While commentating for Triple M Cricket, the Sultan of Swing clearly looked disappointed at the dismissal but he changed his expressions quickly.

The 57-year-old remained silent for most part of the video until he rated Babar's wicket as a big one for the Aussies.

It must be noted that Australia were 84-2 at stumps on day three of the first Test against Pakistan in Perth as they extended their lead to 300 runs.

Steve Smith (43) and Usman Khawaja (34) will resume batting for the hosts on day four.

Australia suffered early setback as David Warner was dismissed for a duck while Marnus Labuschagne was back to the hut after scoring two runs. Both wickets were claimed by Pakistan's debutant pacer Khurram Shahzad.

However, Khawaja and Smith took control of the innings after the early losses as they stitched a solid partnership of 79 runs before the close of play.

Meanwhile, Pakistan were dismissed for 271 in their first innings on the third day with Australia taking a lead of 216 runs.

Pat Cummins confirmed that Australia will bat again and won't enforce the follow-on.

Opener Imam-ul-Haq top-scored for Pakistan with 62 runs in 199 balls with the help of four boundaries.

Abdullah Shafique scored 42, meanwhile, captain Shan Masood added 30 runs.

Pakistan were 122-1 at one stage but then lost their next nine wickets for 149.

Nathan Lyon was the pick of the bowlers for Australia with figures of 3-66. He now has 499 Test wickets and will look to get his 500th scalp in the next innings.

Pat Cummins and Mitchell Starc claimed two wickets each.
