Both clubs headed into their sixth Super League match of the season last Saturday at New Victoria Park both desperate for a win.
But it was Sauchie who took the honours as the Star finished with ten men and out of the points again .
A disjointed looking Newtongrange Star stumbled to their fourth defeat of the season already, conceding their tenth goal and netting only their sixth as Sauchie held the edge in a goalless first half.
The visitors missed excellent chances through David Morrison and Conor Kelly.
While Star’s Matti King hit the side net in 42 minutes in a match full of bookings.
Steven Tulloch was booked in 20 minutes for dissent, a yellow card that was to come back to haunt the Newtongrange man.
However, things looked up for Nitten as they opened their second half with a stunning free kick goal from Craig Thomson in the 48th minute.
Sauchie’s Jordan Tapping had been booked for the foul on Ally Forster which led to the free-lick.
Newtongrange chased a second elusive goal to secure the points but they suffered a double Sauchie whammy in 75 and 77 minutes .
First through Conor Kelly punishing a slack home defence then even worse for Star with Sauchie going 2-1 up as Iain Syme swept home a Brian Morgan corner.
It got worse for the Star next as a second booking for pivot Steven Tulloch saw him sent off and the Star reduced to 10 men.
And Sauchie capped a fine win with Conor Kelly beating the home offside trap in 82 minutes to slot home goal number three for the visitors past Renton.
This Saturday sees Newtongrange away to Bathgate Thistle in the first round of the East of Scotland Cup with the Star eager for a win to kick-start their season.
Newtongrange Star drew home tie in the first round of the Scottish Junior Cup drawn last week at Hampden Park.
The Star will entertain Premier League’s Edinburgh United on September 26.
