Sought-after Rushden striker Simeon Jackson grabbed a brace as the Diamonds caused an FA Cup shock by beating Macclesfield 3-1.
The 20-year-old striker, who had trials at Manchester United two years ago, took his tally to 13 for the season as League Two Macclesfield were slayed in spectacular fashion.
Macclesfield are just 19 places above Rushden and the gap in class never materialised thanks largely to the deadly finishing of Jackson.
The Jamaican-born striker opened the scoring after only seven minutes bundling in Craig McAllister's low cross via the crossbar.
Macclesfield should have levelled on 12 minutes but Martin Gritton fired agonisingly wide when it seemed easier to score, and in first-half stoppage time, they were left with a mountain to climb as Jon Challinor headed home an Andy Burgess short corner to put clear daylight between the teams.
Rushden were in dreamland on 57 minutes as the impressive Burgess nicked the ball in midfield and played in Jackson, who rocketed the ball home from a tight angle.
Simon Wiles and Gritton combined to give Macclesfield a much-needed lifeline on 75 minutes, with the latter heading home a right wing cross.
But for all their possession and territory - Macclesfield were unable to find further goals - becoming the only Football League side to suffer a non-league giantkilling on FA Cup first round day.
