York City climbed out of the drop zone after they ended the best home record in the top four divisions against a Northampton side looking to extend their 10-match winning run at Sixfields.
The relegation battlers beat the Cobblers 2-0 thanks to Ashley Chambers and an own goal from John Johnson to extend their unbeaten run to four games under Worthington while Town slipped to a third defeat on the bounce to lose ground on the automatic places.
Worthington said: "I don't want it to be a case of after the Lord Mayor's Show. We're on a decent little run now but I told the players straight afterwards that this game has now gone and now we focus on next week's fixture and try to build on this result.
"We've worked hard over the last few games and got our rewards, the players are now enjoying themselves. We beat Plymouth, who were doing very well at home, got a point at Bristol Rovers, who had been on a good run, and now we've won at Northampton, who have the best home record in the league.
"Northampton is a very hard place to come with their home record, we knew we had to perform and the players did just that. Northampton's home form has been exceptional and we knew we had to work hard and play when we could.
"Hard work are only two small words but that's what you need in these sort of games. We played well when we had possession and I think we deserved the victory."
After seeing his side slip to their third straight defeat, Cobblers boss Aidy Boothroyd said: "The run was always going to come to an end sometime but I'd rather it had come to an end in six months' time rather than today.
"York dealt with the occasion better than we did. The pressure was on us to get a result and we didn't get it but we dealt with it last season when we were in a relegation fight and we'll deal with it this year when we're in a promotion fight."
Boothroyd refused to put his side's poor showing down to increased expectation at Sixfields and says his players can handle the pressure as they look to hold on to their play-off place and even get back into the top three.
"I honestly don't think the crowd affected us," he added. "It's brilliant to play in front of big crowds and you want to win because you want all those people to come back. There's a reason why we've got one of the best home records in the country and if I lose sight of that and start to panic then that's not what I'm paid for."
