Rod led astray chasing bowling technique (7)
I believe the answer is:
spindle
'rod' is the definition.
(spindle is a kind of rod)
'led astray chasing bowling technique' is the wordplay.
'astray' is an anagram indicator.
'chasing' says to put letters next to each other (some letters chase after others).
'bowling technique' becomes 'spin' (cricket).
'led' with letters rearranged gives 'dle'.
'dle' put after 'spin' is 'SPINDLE'.
(Other definitions for spindle that I've seen before include "Pin bearing a bobbin" , "Axis, pivot" , "Wool-spinning rod" , "Rod on which something rotates" , "Pin serving as an axle" .)
