AUSTRALIA'S batting crisis at Edgbaston could see a reliance on Shaun Marsh to be the saviour that digs them out of the deepest of Ashes holes.
Marsh's recent form has been outstanding, but when you consider the inconsistency that's plagued the West Australian's career, his expected promotion at the expense of Adam Voges for the do-or-die fourth Test at Trent Bridge doesn't necessarily scream miracle solution. 
At 32, Marsh is only three years Voges' junior and, despite possessing all the natural talent in the world, the enigmatic left-hander simply hasn't been able to nail down a Test spot in his four incarnations in the national team - and has struggled against the moving ball.
With a Test average of 35.79 from 14 matches and a first-class average of 39.18 spanning 15 years, there is no other way to describe Marsh's career other than to say it's been mediocre at best. This time it's now or never.
Marsh has promised so many times before, but the positive for Australia is that he is in great form.
Two hundreds from two tour matches so far on this Ashes campaign, and also a solid past five Tests for Australia where he's scored three half-centuries - including an agonising 99 run-out at the MCG.
It's almost certain Marsh will play in Nottingham, but the question is more where he will slot into the order?
Former Test star Rodney Hogg believes Marsh, who in more recent times has played for Australia as an opener, should bat at No.3, pushing Steve Smith to No.4 and Michael Clarke to his strongest position statistically of No.5.
However, the most likely scenario is Marsh would simply come into the No.5 position, where he started every single Sheffield Shield match for WA last season."It's been great that every time Shaun's got an opportunity he's got a hundred in the tour games," Australia"s batting coach Michael Di Venuto said.
