To reach the last eight, ALG Spor pipped Fomget Genclik, Kirecburnu and Dudulluspor to top Group C with nine points, while Kayseri Gencerbirligi ended as runners-up in Group D with five points.
ALG continued from where they left off at Arslan Zeki Demirci Sports Complex until Sunday gave the holders a first-half lead, with the opener in the 33rd minute off a brilliant assist from Ebru Topcu.
After the restart, Kayseri fought hard to get back into the mix but saw their comeback dreams quashed when Toure struck five minutes from full-time to seal ALG s passage to the next round.
