Rarely in trouble, expert passing competition (5,4)
I believe the answer is:
relay race
'passing competition' is the definition.
'relay race' can be an answer for 'competition' (relay race is a kind of competition). I am not sure about the 'passing' bit.
'rarely in trouble expert' is the wordplay.
'in trouble' is an anagram indicator.
'expert' becomes 'ace' (ace can informally mean very good).
'rarely' is an anagram of 'relayr'.
'relayr'+'ace'='RELAY-RACE'
Can you help me to learn more?
(Other definitions for relay race that I've seen before include "track event" , "Ace rarely placed in team event" , "Foot speed contest passing batons" , "Baton-passing event?" , "Team contest" .)
