Report: Chasetown 1 Shaw Lane 2
Skipper Chris Slater became the first person in Chasetown's history to play 400 league games for the club.
But his side suffered a play-off setback to title-chasing Shaw Lane Aquaforce, losing 2-1 at the Scholars Ground.
The Barnsley side took the lead after just four minutes with a quick attack that caught Chasetown out.
When the ball ran into the path of James Walshaw he drilled a left-foot shot past goalkeeper John Bateman.
Chasetown almost levelled with a Francino Francis header which was plucked out of the air by Tom Morgan.
The Yorkshiremen made it 2-0 before 20 minutes, as they visitors broke quickly and Gavin Allott stole in to net from close range.
Chasetown's Paul Sullivan had a goal disallowed for the tightest of offside decisions in a dramatic opening quarter of the game.
Sullivan brought the Scholars back into the game four minutes before half-time seizing on a through ball from midfield and casually lifting the ball over Morgan.
Francis was a whisker away with a header from a corner as Chasetown started the second half brightly and Jed Davies curled a dipping free-kick inches over the bar, as Dave Stringer's men took charge.
On the break, Shaw Lane should have given themselves some daylight but skipper Matt Thornhill blazed a shot off target with just Bateman to beat.
Chasetown were unable to force an equaliser and Shaw Lane remain in fighting distance behind Stafford Rangers in the Evo-Stik Division One South.
