Manager Paul Cook revealed his delight for striker Marc Richards after he struck inside five minutes at a rain-soaked Kassam Stadium to clinch the Spireites' third win in just four games.
The former Port Vale man has been forced to endure a tumultuous season so far - plagued by a recurring hamstring injury - but Richards latched on to Richard Brindley's incisive pass and slotted home with aplomb to put and end to a goalscoring drought that stretched back to mid-January and move Chesterfield to within eight points of the play-off places.
"I'm made up for Marc," Cookie revealed to Spireites Player at full-time.
"Footballers get criticism when things don't go well, that's just the nature of the game we're in. There's no hiding place in football.
"Today Marc scored, we've won, got a clean sheet and there's been a lot of very good performances. It's a happy today, but tomorrow will be a different day."
Richards' seventh goal of the season proved to be enough in dreadful conditions in Oxfordshire, as another resolute defensive display saw the Spireites register their fourth clean sheet in five games.
Former Hull City youngster Liam Cooper put in another monumental performance at the heart of the defence alongside transfer-listed Neal Trotman and Chesterfield's only concession of late remains Paul Benson's 93rd minute header at Whaddon Road.
The result means the Liverpudlian's side have conceded just five goals in 11 games and he is pleased with that his side have finally started to turn the corner after a miserable run during the start of 2013.
"I'm happy with our football team winning, that's the most important thing," he added.
"We got a little bit of criticism for a period of time when people can question what you are doing quite quickly. All of a sudden now, we don't seem to be conceding many goals and winning games.
"But it's the same players and they need to have the confidence on the pitch to express themselves.
The victory moves Chesterfield to within eight points of local rivals Rotherham United in seventh place, as the Spireites make the arduous trip to Torquay United on Tuesday evening.
The Gulls have been in disastrous form lately, having picked up just one win in their last 18 games to slide perilously close to the Football League's trapdoor and manager Martin Ling is also absent following illness.
Former Scunthorpe boss Alan Knill was appointed on an interim basis, but United are among five teams languishing on 40 points at the foot of the table.
"We'll dust ourselves down, the next game is always the biggest one.
"For a football club like ours, we must go there and win that game. If we can go there and do that then it sets us up for a great game on Saturday.
"Oxford have been on a great run, Bristol Rovers have been on a good run and now we're on a little bit of a run ourselves.
"I must compliment our support again today, they were terrific. Every point you get, every win, it's for them as well."
