Caught one making bowlers talk a lot (7)
I believe the answer is:
chatter
'talk a lot' is the definition.
(to chatter is to talk a lot)
'caught one making bowlers' is the wordplay.
'caught' becomes 'c' (cricket abbreviation).
'one making bowlers' becomes 'hatter' (someone who might make bowler hats).
'c'+'hatter'='CHATTER'
(Other definitions for chatter that I've seen before include "Informal talk" , "Idle gossip" , "Trivial conversation" , "Talk incessantly" , "Talk noisily" .)
