Second step upset batsman? (6)
I believe the answer is:
sledge
'upset batsman?' is the definition.
(to sledge is to distract a cricket player)
'second step' is the wordplay.
'second' becomes 's' (common abbreviation).
'step' becomes 'ledge' (I have seen 'A step' mean 'ledge' so perhaps 'step' could also mean 'ledge').
's'+'ledge'='SLEDGE'
(Other definitions for sledge that I've seen before include "Vehicle mounted on runners" , "Put cricketer off" , "In the field, abuse" , "Vehicle for use in snow" , "Make offensive remarks" .)
