Accrington overcame League One Peterborough 2-1 to reach the second round of the Carabao Cup.
The League Two side, who played a preliminary round in the competition last week, struck twice in the first half.
Posh, who got one back late on, have lost all three games of their season so far.
Stanley made a dream start, taking the lead after 37 seconds. A long throw by Freddie Sass into a crowd of bodies was pushed out by goalkeeper Vicente Reyes but only to Alex Henderson who blasted the ball low into the net.
The Reds grabbed a second in the 25th minute when Henderson’s cross was tapped over the line at the near post by Kelsey Mooney.
Posh dominated possession but struggled to test home keeper Ollie Wright with their best chance of the first half – a Harley Mills free-kick which was narrowly wide.
After the restart, Stanley’s Farrend Rawson could have made it three but sent his header straight at Reyes.
In the 54th minute, Gustav Lindgren forced the first save out of Wright, with the keeper diving low to keep out his effort.
Posh got one back after 79 minutes when Archie Collins headed home a Cain Hayes cross, but it was Stanley who threatened in eight minutes of added time, with Josh Woods almost adding a third.
