Simba now need two points from the remaining three games to be named Premier League champions for the 2017-18 campaign.
Pierre Lechantre who enjoyed the first derby win over Yanga last weekend named an unchanged squad to face the Mtwara based side who are fighting for the place to remain in top flight next season.
However, Ndanda produced a remarkable performance to keep Simba at bay for the majority of the first half.
Three minutes before half time, Ugandan striker, Okwi found a path through to fire the home side ahead with a beautiful individual goal.
Okwi started the move from half way and he tried to seek for the assistance from his fellow front men Shiza Kichuya and John Bocco but all of them were under tight security something which led Okwi to dribble inside the area before scoring a nice goal.
It was his 20th goal of the season and now he is the clear favorite for the golden boot award.
After this match, Simba will head to Singida were they will play Singida United on May 12 at the Namfua Stadium and a win will seal the title with two games ito spare.
