Out of practice but try us anyway (5)
I believe the answer is:
rusty
'out of practice' is the definition.
(synonyms)
'try us anyway' is the wordplay.
'anyway' indicates an anagram.
'try'+'us'='tryus'
'tryus' anagrammed gives 'RUSTY'.
'but' is the link.
(Other definitions for rusty that I've seen before include "Reddish," , "Antiquated" , "showing sign of inactivity?" , "Behind the times" , "a bit faded" .)
