Australia's cricketing enigma Shaun Marsh has given his detractors further ammunition, succumbing to a woeful dismissal in the first Test against India.
Marsh fell for two, dismissed by Indian offspinner Ravichandran Ashwin for the fifth time in Test cricket, when he attempted to drive a wide-pitched delivery and dragged it onto his stumps in the first over after lunch on Thursday.
His wicket left Australia 3-59 on day two in response to India's 250.
Marsh, thrust into the role of senior batsman alongside Usman Khawaja in the absence of Steve Smith and David Warner, had tuned up for the Test series with scores of 80, 98, 163 not out and 81 among six Sheffield Shield innings.
But his cheap dismissal at Adelaide Oval, which is certain to embolden his many vocal critics, reinforces the enormous and frustrating gulf between his best and worst.
The left-hander's highest score from his past 13 Test innings is 40 and his six consecutive single-figure scores are the most for any Australian batting in the top five since 1888.
A nervous starter beyond compare, Marsh averages almost 60 when he passes 10 but a remarkable 26 of his 62 Test dismissals - including eight this year - have been in single figures.
Marsh struck career-best form last summer, scoring a man-of-the-match century that delivered Australia a 2-0 series lead and plundering more Ashes runs than any batsman bar Steve Smith.
But he was a non-factor in South Africa and made just 14 runs at an average of 3.5 in the two-Test series against Pakistan in the UAE in October.
"Shocking shot from Shaun Marsh," former Test opener Simon Katich said while commentating on SEN radio.
"He'll be feeling the pressure ... he knows he didn't make any runs in the UAE.
"It's a tough situation ... he's done all he possibly can leading into the Test (by scoring runs in the Sheffield Shield)."
