BLUES boss Brian Reid has urged his side to cut out the silly mistakes if they want to pick up a memorable win over Motherwell tomorrow (Saturday).
Only victory would be enough to see Stranraer finish above the Steelmen in Group F and potentially reach the next round of the Betfred Cup.
Both sides sit together on six points but the visitors' superior goal difference sees them above Stranraer.
Reid was again hoping for a full strength squad to choose from but was equally keen for a different result than Monday night's defeat to Rangers.
He said: "It was always going to be a hard ask against Rangers.
"They are playing well and have signed a lot of good players.
"We are just disappointed with the start we made in the game."
A penalty in the opening five minutes and then a slack back pass saw last season's Championship winners well on top and left the Blues with a mountain to climb.
Reid stressed tomorrow's opposition would be of a similar standard to that faced earlier in the week and pointed out that Motherwell had finished in the top six in the Scottish Premiership last season.
Similarly, while the club and the fans were benefiting from playing two top flight teams, it made it harder for the Stair Park side to progress.
Now, the manager was hoping his players would learn from their mistakes in the final group game.
He said: "The longer you can keep a clean sheet and defend properly the better chance you have of winning any game.
"We are at home tomorrow and there is nothing to lose.
"We are the big underdogs and you can have a go.
"Hopefully there will be a decent crowd and we will see where that takes us."
