Substitute Shaq Coulthirst fired in a late penalty to secure a narrow win for Southend United against York City at Roots Hall.
Luke Summerfield almost put York ahead but his curling effort was pushed wide of the right post by Daniel Bentley.
Russ Penn piled the pressure on the hosts when his close-range header was cleared off the line by Michael Timlin.
Southend clinched three points when Coulthirst fired from the spot after Joe Pigott was felled by Brad Halliday.
York City manager Russ Wilcox told BBC Radio York:
“At the moment the results are not marrying up with the performances unfortunately.
“That’s so important whether you’re at the top of the league or down at the bottom.
“It’s very frustrating. I could feel that coming a little bit because we absolutely dominated the first-half but you’ve got to score when the opportunities come.
“If a neutral was watching today I’m sure he’d be saying we were the top team but it’s important we move forward and go again.”
