Spinner quietly stopping team getting runs (6)
I believe the answer is:
spider
'spinner' is the definition.
(a spider spins webs)
'quietly stopping team getting runs' is the wordplay.
'quietly' becomes 'p' (p for piano and quiet).
'stopping' is an insertion indicator (stopping can mean blocking a gap).
'team' becomes 'side' (I've seen this before**).
'getting' means one lot of letters go next to another.
'runs' becomes 'r' (cricket abbreviation).
'p' going into 'side' is 'spide'.
'spide'+'r'='SPIDER'
(Other definitions for spider that I've seen before include "Arachnid - snooker rest" , "Webster" , "Arthropod; snooker rest" , "Web designer?" , "Bathtub intruder - snooker rest" .)
