Bowler at Edgbaston shows pace (4)
I believe the answer is:
rate
'pace' is the definition.
(I know that pace can be written as rate)
'bowler at edgbaston shows' is the wordplay.
'shows' indicates a hidden word.
'RATE' is hidden within 'bowler at edgbaston'.
(Other definitions for rate that I've seen before include "standard levy" , "Amount measures against another" , "Assign a value to, appraise" , "Value - scold" , "Give a value to something" .)
