I picked up that man (5)
I believe the answer is:
roger
I believe this clue is a double definition.
'i picked up that' is the first definition.
(word used to acknowledge a radio transmission)
'man' is the second definition.
(man's name)
(Other definitions for roger that I've seen before include "Radio acknowledgment" , "Sir - de Coverley, English country dance" , "I get you" , "Romeo's predecessor" , "Message received; name" .)
