Zesco United made minor progress up the FAZ Super Division table on Wednesday when they were held 0-0 away by Power Dynamos.
Zega move to 45 points from 23 games with two matches in hand following the draw in this rescheduled Week 13 match played at Arthur Davies Stadium in Kitwe.
Goalkeeper Dieudonne Ntibahezwa was again in outstanding form for denying Alex Ngonga twice in the 22nd and 33rd minutes.
Zesco’s best chance in a match of few opportunities for the visitors came in the 52nd minute through Maybin Kalengo but Victor Kashitu blocked his tame shot.
David Owino, who had an outstanding game on the day, made a telling interception in the 90th minute when he shielded Kelvin Mubanga from blasting in a sure effort forcing the midfielder to miscued his shot.
Zesco move to 45 points, two ahead of Green Buffaloes whom they face away this Sunday in a Week 25 fixture at Woodlands Stadium in Lusaka.
