Alfie Goodwin's last-minute strike secured Summertown the three points with a 2-1 win against Harwell and Hendred.
Summertown led 1-0 at half-time following an own goal.
But Harwell led a determined fightback, hitting the woodwork three times, and they got a deserved equaliser with a fine 15-yard low shot by Jonathan Green.
However, Goodwin’s five-yard slot past the keeper in the 79th minute gave Summertown victory.
