Cricket scores you heard upped for Ashes holders (4)
I believe the answer is:
urns
'ashes holders' is the definition.
(I've seen this in another clue)
'cricket scores you heard upped' is the wordplay.
'cricket scores' becomes 'snr' (I am not sure about this - if you are sure you should believe this answer much more).
'heard' indicates a 'sounds like' (homophone) clue.
'upped' is a reversal indicator (in down clue, made to go up).
'you' is a homophone of 'u'.
'snr'+'u'='snru'
'snru' in reverse letter order is 'URNS'.
'for' is the link.
(Other definitions for urns that I've seen before include "Runs to get large vases" , "Large vessels for tea" , "Runs to find large vases" , "Large pots for tea" , "Burial vases" .)
