Wycombe striker Dean Morgan netted two first-half penalties as the Chairboys brushed aside York 4-0 to extend their unbeaten run to five games.
Morgan's first spot-kick came in the third minute after he was fouled by Scott Kerr and he then repeated the trick on the stroke of half-time when Jamal Fyfield barged over Joel Grant.
Wycombe's third came from a superb solo effort by Grant just before the hour.
Dave Winfield then headed home Josh Scowen's corner 12 minutes from time.
The Minstermen, without a win in six matches, are now just seven points clear of the relegation places after conceding four goals for the second week running.
Wycombe moved up to 11th, within five points of the League Two play-offs.
VIEWS FROM THE DRESSING ROOM
Wycombe manager Gareth Ainsworth told BBC Three Counties Radio:
"It was a great result, we've probably actually played better in other games than we did today.
"Some of the boys were on three-quarter tanks after Monday's game.
"It was a great performance and great result. In the second half we really turned the screw.
"I'm so pleased we're in the top half of the table, the lads deserve it."
York City manager Gary Mills told BBC Radio York:
"We were obviously very disappointing from start to finish today.
"We're committing suicide at the moment, we're giving goals away and don't look like scoring.
"We'll get ready for the next one and move on.
"The players that are at this football club now have to stand up and start winning football matches."
