League Two side Salford City reached the third round of the FA Cup for a second successive season with a 4-0 upset against League One club Leyton Orient at the Peninsula Stadium.
On a tricky pitch, Orient goalkeeper Killian Cahill diverted Kadeem Harris's first-half cross between his legs and into the net for an own goal to put the hosts in front after 23 minutes.
Kallum Cesay doubled Salford's lead close to the hour mark with a curling shot after another productive run by Harris created the opportunity.
Former Italy forward Fabio Borini slotted home eight minutes after coming on as a substitute, before Kelly N'Mai added a fourth in stoppage time after collecting a long ball over the top and beating Cahill from the edge of the box.
Salford dominated throughout, almost going ahead two minutes before the opening goal when Cahill tipped Luke Garbutt's fizzing drive over the crossbar.
City threatened to score again shortly before half-time when Cahill spilled Jorge Grant's free-kick into the path of Daniel Udoh, but his close-range shot hit the outside of a post.
After Cesay struck, the EFL newcomer teed up Josh Austerfield to lash a presentable chance over the crossbar.
Ex-Sampdoria striker Borini and Dutch midfielder N'Mai's late efforts ensured Salford have now won their past three FA Cup ties against League One opponents, ousting Shrewsbury Town 2-1 in the 2024-25 season and beating Lincoln City on penalties in the first round this season.
