The Sky Blues continued their renaissance under new boss Iain Dowie with a comprehensive victory against struggling Hull City.

A penalty from Michael Doyle and a well-taken header from Leon McKenzie, his seventh goal of the season, put City firmly into the driving seat before half-time and despite some second-half pressure, City held on to claim their first league 'double' of the season.

Top scorer McKenzie was one of two changes Iain Dowie was forced into ahead of the game.

He replaced the banned Kevin Kyle, while the versatile Adam Virgo stepped-in at right-back for Andy Whing, who also sat out through suspension.

A tense start saw both sides intent on not conceding an early goal but City made the brighter openings.

Stephen Hughes skewed a low shot wide and Jay Tabb flashed a long-ranger over the bar while at the other end, goalkeeper Andy Marshall raced off his line to deny Nicky Forster a shot at goal.

But the game sprung into life in the 20^th minute when Hughes was hauled down by David Livermore in the area after a marauding run.

Referee Steve Tanner didn't hesitate in pointing to the spot and with regular penalty taker Colin Cameron injured, Doyle took over the responsibilities and sent a confident strike into the bottom-right corner for his third goal of the campaign.

The Sky Blues continued to pose questions to a shaky Tigers defence and grabbed their reward thirteen minutes later when McKenzie leaped above two defenders to head Isaac Osbourne's teasing cross beyond 'keeper Boaz Myhill from four-yards.

McKenzie threatened to double his tally at the close of the half when he drilled wide after shrugging off Michael Turner, while Stuart Elliott fired narrowly over for Hull.

The visitors kept City at bay after the restart with a brave block denying an Osbourne volley and began asking questions of their own on the hour when Forster dragged a low effort wide and Marshall got down well to claw away substitute Dean Marney's header.

Marshall was proving a thorn in the Tigers' side as he saved a Dean Windass header from point-blank range in the 68^th minute while a timely intervention from Hughes foiled Elliott minutes later when the winger bore down on goal.

Boss Dowie threw on Chris Birchall and Michael Mifsud to reignite a tiring attack, but by that time the game had already started to peter out as the Sky Blues remain unbeaten under Iain Dowie.
