The Australian pace bowler Mitchell Johnson's most telling imprint on the second cricket Test in Adelaide could be a wicketless delivery.
Johnson hopes he maimed West Indian dangerman Sulieman Benn with a classic sandshoe crusher yesterday.
The Windies ended day 4 on 284 for 8, a lead of 296, with captain Chris Gayle unbeaten on 155.
Gayle will decide this morning whether to bat on... the target hasn't been achieved in 100 years of Test cricket at the Adelaide Oval.
Benn, collected five first innings wickets, and loom as the Windies' trump card on the final day.
Johnson says the tall spinner could be the key.
Johnson has 4 for 85 in the Windies second innings.
