As K'Ogalo emerged as winners, the Bankers failed to earn points that would have taken them on par with Tusker
Gor Mahia managed to pick up a 1-0 win over Posta Rangers in their Football Kenya Federation Premier League fixture at Ruraka Grounds on Wednesday.
Samuel Onyango's first-half strike enabled K'Ogalo to avenge a first-round defeat they suffered at the hands of Stanley Okumbi's men.
The Mailmen could have opened the score in the second minute when Eliud Lokuwom made his way into Gor Mahia's area, but he took too long to get composed and allowed Gad Mathews to close in on him and block him from shooting at close range.
