Adult’s run out to scoop up wild poorly animal (9)
I believe the answer is:
Here is my best explanation:
'animal' is the definition.
(armadillo is a kind of animal)
'adult's run out to scoop up wild poorly' is the wordplay.
'adult' becomes 'a'.
'run out' becomes 'ro' (cricket abbreviation).
'to scoop up' is an insertion indicator.
'wild' becomes 'mad' ('mad' can be similar in meaning to 'wild'**).
'poorly' becomes 'ill' ('ill' can be a synonym of 'poorly').
'ro' going around 'madill' is 'rmadillo'.
(Other definitions for armadillo that I've seen before include "Compete against, drama", "Creature", "protected species", "Insect eater", "armour-plated type", "Horny-plated creature", "Long-snouted animal", "Nocturnal creature", "Plated S. Am. animal" and "Horny-plated animal".)
