Called Yorkshire's opener "long-legged" (5)
I believe the answer is:
rangy
'long-legged' is the definition.
(I've seen this before)
'called yorkshire's opener' is the wordplay.
'called' becomes 'rang' (called on the phone).
'opener' suggests taking the first letters.
The initial letter of 'yorkshire' is 'y'.
'rang'+'y'='RANGY'
(Other definitions for rangy that I've seen before include "Tall and thin" , "with long legs" , "Having members at length" , "Long-legged" , "with gangly limbs" .)
