Nathan Broadhead inspired Wrexham to a 2-0 victory over League One Reading to take them into the fourth round of the League Cup for the first time since 1978.
Reading had a proven track record of beating Championship opposition on the way to the third round with a win over Portsmouth in the first round.
However, Wrexham showed their superiority with Broadhead able to net a devastating brace to secure their place in the next round.
Just before the 10th minute, Reading's Mark O'Mahony found space just outside the box and tried his luck from distance but his effort went wide.
