Shrewsbury Town 1-2 Burton Albion Dev
There was little time for Town to respond as Burton went on to claim the Staffordshire County Women's League Cup trophy.
The crucial moment came in the 92nd minute when Smith rose highest from a corner from the right to plant a header right into the top left corner of Town's goal.
The game soon became end-to-end following the equaliser and the Brewers spurned a great chance to claim the victory before they eventually did.
Evans' side continued to push for an equaliser and duly got their reward as Turner poked home past the Burton 'keeper from just inside the penalty area.
Cleveley was then forced to make another two smart saves around her right post within the next seven minutes.
But it was the Brewers who took the lead, in the 57th minute, as Eley went on a lung-busting run through the centre of the pitch and forced a good save from Cleveley from close range before firing the rebound beyond the goalkeeper.
Town again went close to taking the lead within seven minutes of the second half as Owen broke through the centre of the field before seeing her shot at the end well-blocked by a Burton defender.
HALF-TIME: Shrewsbury Town 0-0 Burton Albion Dev
Evans' side had the best chance to open the scoring before the break as Turner completed a neat one-two with Owen on the right before blasting wide, but it was goalless at the interval.
Penny Owen then went direct from a free-kick for the Shrews, from around 25 yards out, but her shot was too high of the target.
The game started with a downpour of rain but it did little to affect Town who started well and Turner had the opening chance in the 9th minute as she went clear on the inside left but dragged her shot wide of the far post.
Sean Evans' side created enough chances to then go on and win the game, but their hearts were broken as Smith fired a stunning header into the top corner, from a corner, right at the death.
The Brewers had taken a second-half lead at Evans Park, the home of Stafford Town, through Nat Eley before Town equalised through Natalie Turner, to a rapturous noise from the Shrews' supporters.
A 92nd-minute winner from Burton Albion Dev's Lacey Smith broke the hearts of the brave Shrewsbury Town Ladies in the Staffordshire County Women's League Cup Final on Wednesday evening. SUBS: Jess Hicks, Kim Winton, Rose Owen.
