Jay Tabb's goal in the 35th minute sealed the points for Coventry City as they beat Cardiff City 1-0 at Ninian Park.
It was a deserved victory for the Sky Blues, who defended doggedly against the Welsh outfit, with some excellent saves from Dimi Konstantopoulos before the break.
It maintains City's unbeaten start to the season, following the win against Barnsley and draw against Hull City.
Coventry even survived the drama of a 90th minute penalty miss from the home side.
Iain Dowie was forced to make two changes from the side which drew 1-1 against Hull City.
Michael Hughes - who was replaced by his namesake Stephen - missed the match because of a thigh strain, while Kevin Kyle was absent because of a hip problem. The big striker was replaced by Dele Adebola, with Leon Best also missing because of a minor knock in training.
The absentees meant that Robbie Simpson made the bench for his first league game, along with Ellery Cairo, who has returned from a hernia problem. Robert Page - against his former club - was also on the bench for the first time this season.
There were no places in the Cardiff City 16 for new signings Jimmy Floyd Hasselbaink and Robbie Fowler.
Cardiff had the first real chance of the game on four minutes, when Gary Borrowdale was caught in possession and Steve MacLean broke through and lifted his shot over the crossbar.
It was the home team who created another opportunity with 20 minutes on the clock. Tony Capaldi broke down the left and delivered a pinpoint cross into the area for Paul Parry, who saw his header held by Konstantopoulos.
Michael Doyle saw his shot deflected wide for a corner with 25 gone, but Osbourne's delivery from the set piece was too long and Cardiff cleared their lines.
Doyle was again involved when he was tripped for a free kick just outside the box with 32 on the clock, but it came to nothing as the ball was fired into the Cardiff wall in a so far frustrating afternoon for the Sky Blues.
But Dowie's men did make the breakthrough on 35 minutes to make it 1-0 - Leon McKenzie's cross catching out the Cardiff defence to find the advancing Tabb, who slid it into the back of the net from close range.
The visitors could have had two just three minutes before the break - Adebola pulling his shot across the goal and just wide of the far post from the tightest of angles.
Konstantopoulos kept City in the game with three excellent saves just before the break - the first from Trevor Sinclair, before an excellent double save at point blank range from Joe Ledley.
After the break, McKenzie had the opportunity to double the score on 62 minutes when he pulled his shot wide of the far post though the striker was substituted on 76 minutes for the pacey Michael Mifsud.
In a largely uneventful second half, substitute Darren Purse had the best chance for the home side in the second period when he headed wide moments after coming on before moments later, fellow substitute Feeney pulled his shot well wide when clean through.
Meanwhile, the Sky Blues could have had their second moments from the end when Purse headed against his own crossbar.
With 89 minutes on the clock, Simpson replaced Julian Gray to make his league debut.
But Feeney was pulled down at the death and Cardiff looked as though they would snatch a point from a penalty - only for Purse to smash his shot against the crossbar.
