Observed South Africa getting wicket (3)
I believe the answer is:
saw
'observed' is the definition.
(I've seen this before)
'south africa getting wicket' is the wordplay.
'south africa' becomes 'sa' (abbreviation).
'getting' says to put letters next to each other.
'wicket' becomes 'w'.
'sa'+'w'='SAW'
(Other definitions for saw that I've seen before include "Spotted" , "Cutting tool - did 23" , "Wise saying or cutting tool" , "Old saying for wood cutter" , "Cutting blade" .)
