Pakistan bowler's savage gesture for 'bunny' Steve Smith

Pakistan leg-spinner Yasir Shah simply loves bowling to Steve Smith.

In the history of Test cricket, perhaps only Stuart Broad enjoys bowling to arguably the world’s best batsman more.

'STINKER': Marnus Labuschagne survives clanger to notch maiden Test ton

On day three at the Gabba, Shah clean bowled Smith for just four runs - the seventh time the spinner has dismissed the Aussie batting sensation.

That puts him second behind only Broad in the world standings, with the England quick having removed Smith on eight occasions.

Smith tried to belt Shah through the leg side during Saturday’s first session but in a rarely seen moment, missed the ball completely and was clean bowled.

Commentating for Fox Sports, Test great Allan Border called it a "strange" innings and Shane Warne said it was like Smith didn't have much respect for Yasir Shah".

To make matters worse for Smith - who only lasted 10 balls at the crease - Shah knew exactly how many times he'd removed Smith.

The Pakistani spinner flashed seven fingers to the former Aussie captain as he trundled off the ground - rubbing it in to Smith in brutal fashion.

Smith's wicket and meagre total left viewers in a genuine state of shock, with some labelling him Shah's "bunny".

The dismissal left Smith 23 short of the 7000-run barrier, which he will become the quickest to pass if he does in his next five innings.

Labuschagne belts maiden Test ton

Arguably story of day three belonged to Smith's teammate Marnus Labuschagne, whose brilliant innings saw him notch a maiden Test century.

Labuschagne's superb knock helped the hosts make it to 3-395 at lunch and extend their advantage further against Pakistan in the afternoon.

After centurion David Warner and Smith went in quick succession, Labuschagne was the star of the morning as he romped out of the blocks and endured some nervous moments in the 90s.

The Queenslander brought up his century after 200 minutes at the crease, edging Shaheen Shah Afridi for four and immediately roaring in joy.

The knock further strengthen's Australia's top-three security, after Joe Burns all but locked in the opening role for the summer on Friday as his 97 formed part of a 222-run partnership with Warner.

Matthew Wade - batting at No.5 ahead of Travis Head - made a solid 60 before the latter departed for 24.

Warner meanwhile added just three to his overnight score in a tough first hour for the Australian opener.

After resuming on 151, he battled away against the Pakistan quicks before becoming teenage sensation Naseem Shah's first Test wicket.

Set up earlier in the over, Warner was on caught behind when the ball brushed the back of his bat as he attempted to evade a short ball.

Australia's captain Tim Paine has made no secret of the fact he wanted his side to bat through the majority of day three as they pursue an innings victory.
