Skipper Elly Asieche scored for Batoto ba Mungu with Luke Namanda equalizing for the hosts.
It took the 2009 champions just six minutes to open the scoring. Titus Achesa was left unmarked in a good area and he brought in a good cross which Asieche tapped in.
The Brewers almost equalized in the 15th minute when Boniface Muchiri was let loose in the danger zone but goalkeeper Kevin Omondi pulled a fantastic save to deny him.
In the 20th minute, the 11-time champions were caught in a counter-attack. Achesa managed to find Nixon Omondi in the danger zone but Mboya managed to make a save and deny Batoto ba Mungu.
The Robert Matano-led charges equalized in the 25th minute. Kevin Okoth’s shot was parried by the goalkeeper and the ball kindly fell to Namanda who did not hesitate to head it in.
Sofapaka had a chance to get another goal in the 40th minute. Achesa managed to beat defender Eugene Asike. But he lacked the composure to beat goalkeeper Robert Mboya.
After the break, the visitors continued to push for the second goal and it almost came in the 60th minute. Paul Kiongera received the ball in a good area and took a shot but Mboya was in a good position to stop him.
Moments later, Lawrence Juma managed to beat the goalkeeper but Rodgers Aloro made a goal-line clearance to deny him.
Both teams increased the tempo hoping to get the winning goal, but neither managed to get it.
The Brewers are now in third position with 11 points after six games while Sofapaka are 11th with four points from five games.
