The first two matches of September, the Cardinal hosted two East Coast teams: the Colonial Athletic Association's Northeastern Huskies, and the Atlantic 10's VCU. The weekend slate saw the Cardinal pick up two shutouts and two victories over the Wildcats and Rams, winning 1–0 and 2–0, respectively. Slater Meehan's 37th-minute goal off a corner proved to be the difference against Northeastern. Against VCU, Foster Langsdorf and Adam Mosharrafa netted their first goals of the season. Langsdorf's goal came off of a throw in from Eric Verso, while Mosharrafa's goal was the result of a loose ball in the goal box. The weekend victories saw Stanford jump from 16th to 13th in the NSCAA rankings for week two. On September 10, the Cardinal hosted their cross-town rivals, San Jose State. Langsdorf netted his second goal of the season giving the Cardinal a 1–0 edge over the visiting Spartans. The goal came off a counterattack, where Corey Baird stole the ball from SJSU's Jonathan Colunga, and fed the through ball to Langsdorf. On the 13th of September, Stanford went on the road to Texas to take on the SMU Mustangs. Brandon Vincent found the back of the net to give the Cardinal the lead in the 10th minute against the Mustangs. Morris doubled the lead for Stanford shortly after halftime. A late second half surge of goals from SMU's Christian Boorom and Mauro Cichero tied the match, 2–2, forcing overtime. In the second period of overtime, Eric Verso netted his first goal of 2015, giving the Cardinal a 3–2 victory over the Mustangs, improving their overall record to 5–1–0. On a five-match winning streak, the Cardinal soared from 13th to 4th in the NSCAA national rankings, and 1st in the NSCAA West regional rankings. Stanford would subsequently close out September with a pair of home matches against the West Coast Conference's San Francisco Dons, and the Atlantic 10's Davidson. Thomas Hilliard-Arce braced twice in the first half against San Francisco to score his first two goals of the season. David Garrett would pull one back for the Dons in the 47th minute, only for Morris to score an insurance goal for Stanford in the 59th minute. Shortly thereafter, the Dons' Davi Ramos was ejected from the match for a violent challenge on Langsdorf.
