Arniston boss Jock Landells only had a barebones of 12 players at his disposal with himself on the subs bench for this match.
No fewer than six players were unavailable due to work commitments, holidays and injuries yet Arniston put in a good shift only to lose out agonisingly in the 92nd minute.
Scott Garden was also brought out of retirement to assist the Arniston shortage.
A low key goalless first half saw Arnie keeper Dale Cornet produce one superb tip over save in an evenly contested first 45 minutes on a strength-sapping pitch which had Greig Callaghan all aching at the end.
Arniston were the better team in the second half and in the very first minute a chance to Darren Leslie saw his header hit the side of his head and slip wide.
Bathgate didn’t really impose themelves in the second half but Arniston somehow seem to go off the boil late on in games losing late goals this season to Renfrew (Scottish Cup), Musselburgh, Tranent, Haddington and now Bathgate.
Arniston fought well and looked to have found a winner in the 90th minute netted by Lumbert Kataleza only to be ruled offside by the referee despite the referee not seeing a Bathgate player on the goalline at the other post.
It was all the more galling for Arniston as just two minutes later into time added on, a Gary Harris shot took a wicked bounce off a rough playing surface and beat Cornet as the ball bobbled over the line for the winner.
Arniston’s 4-3-3 line had performed well enough to earn a share of the points but fortune smiled instead on the Thistle.
Next for Arniston this Saturday is a visit to Tayport then the following weekend they are home to current second top of the Premier League title chasing Forfar West End, five points behind top Kennoway but West End have two games in hand.
Arniston Rangers: Cornet, Langdale, Deland, Callaghan, Brady, Somerville, Leslie, Tobin, McFadden, Kataleza, Porteous. Subs: Doig, Garden, Landells, Ritchie.
