In the keenly contested encounter, the first half ended goalless despite the hosts dominating ball possession.
Bulent Uygun’s men came out stronger in the second half, albeit, it was Goztepe who took the lead in the 56th minute through Halil Akbunar.
Following a poor clearance from Fabricio Baiano, the Turkish midfielder slotted the ball past goalkeeper Gokhan Akkan.
12 minutes to full time, Ndiaye doubled the advantage for Unal Karaman’s side – with the visiting side getting punished for another defensive calamity.
Rizespor’s ambition of getting at least a goal suffered a big blow as Akkan was given his marching orders for dangerous play.
