Second team players in something sticky (5)

I believe the answer is:

resin

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

'something sticky' is the definition.

'second team players in' is the wordplay.
'second team players' becomes 'res' (I can't justify this - if you can you should believe this answer much more).
'res'+'in'='RESIN'

Can you help me to learn more?

(Other definitions for resin that I've seen before include "Sticky stuff oozing from trees" , "Exudation from fir trees" , "Substance from tree-sap" , "hashish, say" , "Sticky stuff as from pine tree" .)

I've seen this clue in the Evening Standard.
