Johannesburg - Home favourites the Warriors have won the toss and opted to bat first in the Champions League Twenty20 final against India's Chennai Super Kings.
Both teams have retained the same lineups that won semifinal matches for Sunday's tournament decider at the Wanderers in Johannesburg.
Chennai is chasing a Champions League-Indian Premier League double. Warriors are South Africa's current T20 champions.
The final is a rematch of the group game earlier in the week, when Chennai won by 10 runs to seal its place in the knockout stage.
In the semifinals, Chennai beat Bangalore on Friday and Warriors overcame South Australia in Centurion on Saturday.
