Tusker were seeking to make it eight wins in a row but Sharks remained tight at the back until the final whistle. However, the brewers should blames themselves for not winning this match that they dominated.
The draw was however, enough to take the champions to the summit of the 18-team league after Gor Mahia went down 2-0 to Sofapaka at Kinoru Stadium in Meru. Elsewhere, Ulinzi Stars were forced to come from a goal down to grab a 1-1 draw against Sony Sugar.
The sugar millers took a deserved lead through Amos Asembeka before Stephen Waruru salvaged a point for the soldiers. In another match, Kakamega Homeboyz and Zoo Kericho shared the points after a 3-3 draw while Bandari and Western Stima finished 0-0.
Tusker are now top of the table on 28 points, one adrift of second placed K'Ogalo while Ulinzi Stars move third on 25 points.
