Pat's logo designed for sports fixture (8)
I believe the answer is:
goalpost
'sports fixture' is the definition.
(piece of equipment used in sports)
'pat's logo designed' is the wordplay.
'designed' indicates an anagram (designed with the letters).
'pats'+'logo'='patslogo'
'patslogo' anagrammed gives 'GOALPOST'.
'for' is the link.
(Other definitions for goalpost that I've seen before include "woodwork" , "one unfairly moved" , "it's unfair to move" , "One of four supporters at ends of pitch" , "One propping up the bar" .)
