Petrasso brace downs Barnsley
Goals from Devante Cole and Conor Hourihane early in the game put the hosts in control. But Garry Thompson then pulled a goal back before Petrasso’s double completed an impressive comeback.
Cole gave the home side an eighth-minute lead after Hourihane’s ball found him in space on the left-hand side of the area.
The roles were reversed four minutes later when Cole side-stepped goalkeeper Roy Carroll before squaring to Hourihane who scored with ease.
Thompson pulled a goal back for County moments later, though, when he beat keeper Ross Turnbull with a fine long-range effort after the ball dropped invitingly for him.
Ryan Williams went close to restoring Barnsley’s two-goal advantage before the break with a low shot which struck a post.
Petrasso met Thompson’s cross with a close-range header to equalise just after the hour mark and he then scored a 71st-minute winner after finding a way through the home defence.
