Yes, ten points scored with big hits (5)

I believe the answer is:

sixes

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

'yes ten points scored with big hits' is the definition.
I can't tell whether this definition defines the answer.

'yes ten points' is the wordplay.
'yes ten' becomes 'six' (I can't justify this - if you can you should believe this answer much more).
'points' becomes 'es' (E is an example).
'six'+'es'='SIXES'

Can you help me to learn more?

(Another definition for sixes that I've seen is " Top roll of dice".)

I've seen this clue in the Evening Standard.
