Second bowler, Armstrong for example? (8)
I believe the answer is:
spaceman
'armstrong for example?' is the definition.
(I know that Neil Armstrong is a spaceman)
'second bowler' is the wordplay.
'second' becomes 's' (common abbreviation).
'bowler' becomes 'paceman' (I've seen this before).
's'+'paceman'='SPACEMAN'
(Other definitions for spaceman that I've seen before include "Armstrong, say" , "one requiring a supply of oxygen?" , "Out-of-this-world chap?" , "Astronaut" , "Armstrong, perhaps?" .)
