Senior citizen bats alongside opener (3-3,9)

Ross

I believe the answer is:

old-age pensioner

'senior citizen' is the definition.

'bats alongside opener' is the wordplay.
'bats' is an anagram indicator (slang for mad).
'alongside'+'opener'='alongsideopener'
'alongsideopener' anagrammed gives 'OLD-AGE PENSIONER'.

I've seen this clue in The Times.
