Senior bowled Henry out regularly (5)

I believe the answer is:

older

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

'senior' is the definition.
(I know that senior can be written as older)

I don't understand the rest of the clue.

(Other definitions for older that I've seen before include "Former" , "Advanced in years (but wiser?)" , "Less young" , "as we all will be tomorrow" , "Getting on" .)

I've seen this clue in The Telegraph.
