The Marsh brothers are among a bunch of batsmen who blew a chance to find form on Saturday in Sheffield Shield ranks.
While Test incumbent Marnus Labuschagne made 52, Shaun Marsh (21), his brother Mitch (1), Peter Handscomb (4) and Matt Renshaw (21) fell cheaply in Shield games.
Shaun Marsh resumed on nine against South Australia on Saturday in Adelaide but barely settled before nicking to first slip.
Sibling Mitch lasted only four balls, playing defensively and edging to second slip.
In Canberra, Queensland opener Renshaw's bid to press his claims was cut short by Test spinner Nathan Lyon.
Renshaw, facing NSW's Test-strength bowling attack, survived 68 balls before being caught behind, one of Lyon's four victims.
Another Queensland batsman in the conversation for next month's Test series against India, Joe Burns, made just six before falling to Test quick Josh Hazlewood.
Labuschagne found form with six boundaries in his half-century batting at first-drop.
Blues paceman Pat Cummins took 3-41, Mitchell Starc 1-71, Hazlewood 2-53 and Lyon 4-83.
That quartet is certain to feature in the series opener against India from December 6 in Adelaide.
