Africa Sports of Ivory Coast scored early and late to complete a 2-0 victory over Goldfields of Ghana in a hard-fought West African clash.
With the first leg having finished goalless, Lassina Dao put Sports in the driving seat after just five minutes.
An away goal would still have sent Goldfields through, and Ivorian nerves were stretched until Ambroise Seri scored two minutes from time.
