The team resumed exhibition play in 2010 with the goal of returning to league play in 2011 in a league below Major League Soccer with Barton as head coach. In November 2010, during their final exhibition season game, the club announced that they would be returning to competitive league play in 2011 in the National Premier Soccer League, and that the team was being sponsored by Umbro. In January 2011 it was revealed that the team would be playing in the revived Southwest Division of the NPSL and the team would be playing their home games at the football/soccer stadium on the campus of Westview High School on the north side of San Diego. The move from their exhibition location in downtown San Diego was the decision of Flash Soccer CEO; Clent Alexander, for the team to play in a more modern facility. 2011 season The Flash had a successful first season in the National Premier Soccer League going 12–1–1 on the field (10–3–1 officially due to two forced forfeits on technicalities). Their record was good enough to place first in the NPSL Southwest Division and home field for the first round of the 2011 playoffs. The Flash however were unable to defeat the defending NPSL champion Sacramento Gold in the first round of the playoffs losing 2–1. 2012 season The 2012 season did start on a somewhat sour note for the Flash having been eliminated from the US Open Cup by their crosstown rival San Diego Boca FC. However, the Flash's second campaign in the NPSL ended up proving just as successful as the first with the team going 11–2–1 with a 13-game unbeaten streak, including having gone unbeaten at home, that was not ended until the last game of the season. For their second NPSL year the team moved from Westview High School to the stadium at Del Norte High School near Poway. The Flash developed several players over the course of the season who earned trials with the San Jose Earthquakes of Major League Soccer. Near the end of the season the team itself enjoyed its two largest home crowds to that point and also began exploring the possibility of moving to the Division 2 North American Soccer League with Alexander presenting a letter to and meeting with the NASL. The team did suffer from a second consecutive early exit from the playoffs in the divisional semi-final
