Green Eagles on Saturday enhanced their hopes of qualifying for the 2019 FAZ Super Division championship playoffs when they beat Circuit City 1-0 away in Lusaka.
The victory at Edwin Emboela Stadium saw Eagles maintain their three-point lead with two games left to play in Pool B.
Midfielder Spencer Sautu scored the all-important goal in the 66th minute to send Eagles to 32 points from sixteen games played.
Victory in their penultimate match next weekend at home in Choma against mid-table Lumwana Radiants could just see Eagles clinch their championship playoff place with a match to spare.
In second place are Buildcon on 29 points who twice had the post to thank for their 1-0 Ndola derby win over Forest Rangers at Levy Mwanawasa Stadium.
Defender Isaac Shamujompa scored a screaming long-range free -kick in stoppage time of the 90 minutes to keep Buildcon on course for a debut continental qualification spot.
In third place are Nkwazi who scrambled a 1-1 away draw at seventh placed Nkana.
Shadreck Malambo put Nkana ahead in the 24th minute but Nkwazi midfielder Mathews Nkhowani denied them their first win in four games when he equalized in the 82nd minute at Nkana Stadium in Kitwe.
Meanwhile, Nkana must now ensure they win all their four remaining games, that include two matches in hand, and hope Nkwazi and Buildcon falter in their last two fixtures to pull off a miracle second place finish in Pool B at the end of the month.
