Support, taking a better grip? (6)

Ross

I believe the answer is:

uphold

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

'support' is the definition.
(upholding is a kind of supporting)

'a better grip?' is the wordplay.
'a better' becomes 'up' (I can't justify this - if you can you should believe this answer much more).
'grip?' becomes 'hold' (synonyms).
'up'+'hold'='UPHOLD'

'taking' acts as a link.

Can you help me to learn more?

(Other definitions for uphold that I've seen before include "Support a decision or belief" , "'Support, the law say (6)'" , "Confirm or support, say a verdict" , "Champion" , "Support, maintain" .)

I've seen this clue in the Evening Standard.
