John Mensah scored the only goal of the game as Ghana opened up their African Cup of Nations campaign with a win over Botswana.
However, the match ended on a sour note for the Ghana skipper as he was later handed a straight red card.
The Black Stars controlled large parts of opening half and finally broke the deadlock with 24 minutes played. The former Sunderland centre-back reacted quickest to head in a corner from close range.
Ghana ended the match a man light when Mensah was handed his marching orders for a tackle on Jerome Ramatlhakwane.
