A GOAL four minutes from time sent Chester to only their third Conference defeat of the season on Friday.
Steve Guinan fired home from the edge of the box to snatch victory for a hard-working Hereford side who kept in the thick of the promotion race.
Both sides played well and one goal was always likely to be enough to snatch the points. In an end-to-end highly competitive contest both sides went close in the first half, Jon Brady foiling United's Andy Tretton with a goal-line clearance and Wayne Brown's save denying John Grant.
Chester's best efforts came from Ryan Sugden, now serving a three-match ban, and Scott Guyett who was close with a header.
Chester thought they had grabbed the winner when substitute Michael Brown headed a Kevin McIntyre corner against the post and Matt Baker was forced into a save from Daryl Clare.
Said City boss Mark Wright: `It always seemed it wasn't going to be our night. I thought maybe we lacked a bit of sparkle, but credit to Hereford. They are a good, well organised side.'
