CHATSWORTH — Through 80 minutes, neither North Hall nor North Murray could generate much in the way of offense. By the time the extra 10 minutes of overtime were done, North Hall had done just enough. Junior Avalos scored on a backside header past North Murray keeper Manuel Gonzalez in the first overtime period on Thursday, and the Trojans’ patient passing offensive strategy paid off for a 1-0 win over the Mountaineers in the first round of the Class AAA state playoffs.
