A late flurry of goals saw Ascot United take three points at Lowther Road as they turned the game around to beat Wokingham & Emmbrook.
The Sumas took the lead through Gethin-Barkway after an hour, but the Yellamen levelled up with 20 minutes to go from Harry Grant.
With the game all square heading into the 90th minute, Ascot ensured they took maximum points with late strikes from Ollie Harris and Keaton August.
The hosts had the first cutting edge chance of the game when a sublime through ball from Marcus Whittaker put Gethin-Barkway through on goal, but Ascot goalkeeper, and former Reading and Portsmouth player, Jamie Ashdown called on his experience to rush off his line and make a smart stop.
Wokingham continued to create when positive work down the right byline from Jack Sharman saw him slide in an inviting cross, but there was no one in an Orange shirt to meet it.
Ascot responded with some chances of their own and forced goalkeeper Sean Woodward, who marked his 250th appearance for the Sumas, into an excellent reaction save as he flew to his left to keep out Dan Bailey’s header.
Woodward then bettered that save when he again flew to his left to turn behind Walter’s shot for a corner which meant that the teams went in goalless at the break.
Ascot started the second-half strongly when Walters powered into the box and came close when Woodward’s initial save was almost turned in on the rebound.
Wokingham thought they had taken the lead when a fierce shot from Whittaker was tipped onto the post by Ashdown and Sharman pounced on the follow up only to be denied by the offside flag.
But just a few minutes later the Sumas did break the deadlock when Whittaker looped the ball over Ashdown and Gethin-Barkway was on hand to finish with a header.
Ascot levelled up with 20 minutes to go when Grant reacted quickest from Woodward’s save to tap the ball into the empty net.
With both teams searching to find a winner, it was Ascot who made the incisive breakthrough in the 89th minute when Harris was in the right place at the back post to convert from a floated cross.
Ascot then caught the Sumas on the counter in stoppage time when they broke quickly and August looped the ball cleverly over Woodward to seal the points.
