Danny Peckham netted a free kick midway through the first half to put the Warriors on top 1-0. Webster controlled much of the rest of the game. A second clinching goal seemed imminent.
However, Kyle Piatrowski tied the game with 11 minutes remaining on a determined solo effort.
Schroeder put a ton of pressure on after that and finally cashed in when Rozzano's low shot from the top of the box narrowly slipped inside the left post.
