I'm a little stuck... Click here to teach me more about this clue!

'captivating draw' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'opener gets run out' is the wordplay.
'opener' becomes 'start' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'gets' is an insertion indicator.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'run' anagrammed gives 'urn'.
'start' placed within 'urn' is 'STAR-TURN'.

'in' acts as a link.

Can you help me to learn more?

(Other definitions for star turn that I've seen before include "Headliner" , "Top act" , "Most impressive act" , "Leading act" , "Top item in entertainment" .)
