Doesn't give up going around ward saving for their teams (7)

I believe the answer is:

keepers

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

'teams' is the definition.
Although both the answer and definition are plural nouns, I cannot see how they can define each other.

I can't explain the rest of the clue.

Can you help me to learn more?

(Other definitions for keepers that I've seen before include "Custodians, stewards" , "Zoo attendants" , "Players in goal" , "Goalies" .)

I've seen this clue in the Irish Times.
