Troy Deeney is still awaiting his first win in charge of Forest Green after Mathew Stevens missed a stoppage-time penalty in their 2-1 defeat to Swindon in League Two.
Daniel Kemp’s brace had the Robins ahead going into eight minutes of added time.
And they held on for a first win in five games as goalkeeper Lewis Ward saved Stevens’ spot-kick.
Swindon took the lead 11 minutes into the second half when Jake Young’s deflected cross came to Kemp
on the edge of the area and he lashed the ball into the net.
Rovers equalised in the 75th minute when a low ball into the near post was flicked home by substitute Matt Taylor.
But the lead only lasted seven minutes. Tyrese Shade darted in behind the visitors’ defence and
drilled a low ball in towards the near post where Kemp arrived to thump home.
Rovers had the chance to earn a point when Young conceded a penalty in the sixth minute of added time.
Stevens went down the middle with his spot-kick but Ward stood firm to earn Swindon victory.
