One's driven up river on island (5)
I believe the answer is:
skyer
'one's driven up' is the definition.
(cricket hit which goes up high)
'river on island' is the wordplay.
'river' becomes 'r' (abbreviation for river).
'on' means one lot of letters go next to another.
'island' becomes 'skye' (I've seen this before).
'r' put after 'skye' is 'SKYER'.
(Other definitions for skyer that I've seen before include "shot up" , "Lofty ball" .)
