At least a dozen deliveries, stolen or missed (8)
I believe the answer is:
overshot
'missed' is the definition.
(overshooting is a kind of missing)
'at least a dozen deliveries stolen' is the wordplay.
'at least a dozen deliveries' becomes 'overs' (one cricket over comprises six deliveries).
'stolen' becomes 'hot' (I've seen this before).
'overs'+'hot'='OVERSHOT'
'or' acts as a link.
(Other definitions for overshot that I've seen before include "was pitched wrong?" , "Passed beyond the mark or runway" , "needed to pull back?" , "Went too far" , "Went beyond the mark" .)
