Rainworth were beaten 2-0 by high-flying Spalding United after refeering decisions and an own goal proved to the be difference.
Spalding went in to the game unbeaten in their last 14 games and having won 11 of them.
But Rainworth gave the Spalding a game to remember on a tricky pitch which made playing good football difficult.
In the ninth minute it was Rainworth who nearly opened the scoring as Gino Kelleher’s throughball found Romello Nangle, but Michael Duggan did well to narrow the angle and his effort found the side netting.
Spalding were the next to threaten and only a double save by debutant David Reay from Lewis Webb and Jordan Hepenstall prevented them taking the lead.
Rainworth threatened again when another debutant Eliot Brown outpaced the defence, but Duggan just managed to save at the expense of a corner.
Chances were limited and Hepenstall and Webb both put theirs well wide for Spalding.
The closest Spalding came to scoring was in the final minute of the half Dan White blocked Lee Clarke’s goalbound shot at the expense of a corner.
From the corner Jamie Stevens powerful header just went over in what was to be the last action of the half.
The start of the second half continued much as the first with any chance of a passing game ruined by the state of the pitch.
The 48th minute saw Spalding take the lead when, as the ball was cleared, Theo Brown appeared to have been caught from behind by Hepenstall.
But the referee waved play-on and as the ball was played back Tom Waumsley met it and placed it into the net.
Rainworth had the next chance, but Dean Freeman’s effort was just wide, before debutant Eliot Brown’s effort was blocked and Kelleher put the rebound over.
Then yet another moment of controversy as Nangle was just going past the last defender when he appeared to be pulled down by Stevens, but once again the referee waved play-on.
Spalding made the game safe with virtually the last kick of the match when Jack McGovern’s speculative cross took a wicked bounce and ended in the net. Whilst the goal will be credited to him, in reality it should be credited as a ‘pitch’ own-goal as on anything like a normal pitch it would have bounced harmlessly by.
Rainworth must pick themselves up for they have a huge six-pointer next Saturday at Market Drayton and nothing but a win will do if they are to improve their chances of escaping relegation.
