AFC Blackpool 1, Chadderton 0 BLACKPOOL weren't at their best but a late Chris Brown goal stretched their lead in the Vodkat first division and their winning run to eight league games.
Manager Stuart Parker admitted substitute striker Brown probably would not have been on the pitch to net the 82nd-minute winner but for an injury to Gary Fawcett.
It followed a teasing run down the wing by the in-form Ben Waddington, whose cross rebounded off Chadderton keeper Lee Swanson's legs for alert Lancaster University student Brown to pounce.
Blackpool, now four points clear and with games in hand on the chasing pack, were much improved in the second half at Common Edge.
Parker said: "Probably for the first time all season we were a bit off the pace in the first half and lacklustre.
"We did not adapt too well to their sweeper system, but we showed desire in the second half and just about deserved the win."
In a game of few chances, Blackpool stood firm at the back, with Ford and Baker outstanding, but they had one heart-in-mouth moment in the first half when a 35-yard Chadderton effort bounced off the top of the bar.
Niall Cummins had a chance for AFC but it was James Walker who went closest for the home side before Brown's late intervention.
Walker struck the bar with a stunning free-kick and was later denied by a top-drawer Swanson save.
Parker, who argued that only the league's best referees should take charge of such top-of-the-table clashes after last Monday's ill-tempered win over Wigan Robin Park, was perfectly satisfied with Saturday's officials who dismissed a Chadderton player late on following an altercation with Waddington.
For the second match running, AFC have beaten the side standing second in the table at start of play, so Parker understandably fears no-one.
He added: "I think the only team to have matched us over 90 minutes have been AFC Liverpool but they are inconsistent and lost on Saturday (hammered 7-1 at Whitley Bay in the FA Vase)."
