New matador runs around, haphazardly (2,6)
I believe the answer is:
at random
'haphazardly' is the definition.
(I know that haphazardly can be written as at random)
'new matador runs' is the wordplay.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'runs' indicates anagramming the letters.
'n'+'matador'='nmatador'
'nmatador' is an anagram of 'AT RANDOM'.
'around' is the link.
(Other definitions for at random that I've seen before include "Indiscriminately" , "In no prearranged order" , "unplanned" , "willy-nilly" , "without purpose" .)
