Ball delivered underarm - and red too, surprisingly (9)
I believe the answer is:
deodorant
'ball delivered underarm' is the definition.
I can't judge whether this defines the answer.
'and red too surprisingly' is the wordplay.
'surprisingly' is an anagram indicator (a surprising ordering of the letters).
'and'+'red'+'too'='andredtoo'
'andredtoo' is an anagram of 'DEODORANT'.
Can you help me to learn more?
(Other definitions for deodorant that I've seen before include "Remover of smells" , "Underarm spray, perhaps" , "Substance that removes unwanted smells" , "Toiletry product" , "Smell masker" .)
