Ghana, after a labored first half, bounced back with spirited performance in the second half to score three goals.
Mohammed Kudus shot Ghana into the lead with a tap-in in the 53rd minute after a good run and pass from AS Roma forward Felix Afena-Gyan.
Afena-Gyan found himself on the scoresheet with an absolute peach of a poacher’s finish after connecting Gideon Mensah’s cross.
Osman Bukari completed the thumping with a great solo effort in the 86th minute by rounding the Malagasy goalie and slotting it in an empty net.
The victory has pushed Ghana to first in Group E after Angola defeated the Central African Republic 2-1.
The win is Otto Addo’s first as head coach of the Black Stars of Ghana.
Next up for the Black Stars is an away encounter against the Central African Republic on Saturday, June 4, 2022.
