Phillip Hughes has already been dropped but there's another left-handed Australian batsman who made a blazing start to Test cricket but has recently found runs hard to come by.
Only a week ago Michael Hussey led Australia to victory for the first time on this tour but his place in the Test side becomes more tenuous with every failure.
Throughout much of Hussey's career he has had the Midas touch. His average hovered in the 80s after 20 Tests and at the start of the last Australian summer was still in the mid 60s.
But since arriving back from India last year, Hussey has averaged a paltry 22.38 from his past 11 games. He is without a century in 25 innings and posted only three fifties from his past 20 knocks.
They are far from the figures which would have a 34-year-old feeling confident about his long-term job safety.
If not for Hughes' run of outs, then Hussey's position would be under intense scrutiny
Australia's only reserve batsman, Shane Watson, has already been deployed and it's hard to imagine Hughes being reinstated while concerns still exist with his game so it's likely Hussey will see out this series.
Also in his favour is his excellent form in the tour games.
He made a big century against an attack led by Graham Onions and Steve Harmison at Worcester, and was unconquered in Northampton but has been below par when it matters.
In his four innings this series, Hussey has twice been bowled shouldering arms, which is alarming given batsmen's careers are carved on an awareness of where their off stump is.
Hussey said he was working hard to correct a technical deficiency, picked up by captain Ricky Ponting.
"I was looking out towards mid-off which gave me a slight blind spot," he said in between the Lord's and Edgbaston Tests.
"I couldn't quite pick the ball up as early out of the bowler's hand as I would have liked so I've just tried to open up my eyes up a little to look straight at the bowler which allows me to pick the ball up a little earlier out of the bowler's hand."
Four years ago, Matthew Hayden suffered a near terminal slump in England but saved his hide with a ton at The Oval.
Hussey may need a similar feat to make sure he's at the Gabba when the Australian Test season kicks off against the West Indies in late November.
