With Sam Norton-Knight suffering from a minor hamstring injury Ceri Sweeney moved from the bench to play 10 and kicked off proceedings.
However it was the Glasgow 10, Dan Parks that got the first score with a penalty in front of the posts.
The Blues looked threatening early on with Cooper breaking down the left and feeding Andy Powell who beat his man, but then chipped over the top when maybe a pass inside would have been the better option. A great chip by Mustoe down the left also looked promising before Glasgow were penalised and the Blues elected to kick for touch and attack from the lineout. However Glasgow won the ball and cleared.
Parks converted another penalty before Andy Powell went for an ambitious drop goal that fell short. Glasgow threatened with a kick through from Colin Gregor but great covering by Gareth Williams and Andy Powell prevented the try.
Within minutes, Gavin Evans showed great hands and speed with a break into the Glasgow twenty two with Gareth Thomas carrying on the move, but again the Blues failed to capitalise. The Blues seemed to be penalised more often than Glasgow and the supporters showed their displeasure and Parks failed with his next penalty attempt.
Again Powell broke the defence and passed on to Warburton who continued the move in the Glasgow twenty two and finally the Blues were awarded a penalty but Halfpenny hooked it wide.
The half ended with Thom Evans following up a neat kick to touch down and score. Parks was wide with the conversion.
Half Time Cardiff Blues 0 Glasgow Warriors 11
The Blues were again penalised early in the second half but Parks failed to capitalise hitting the upright with his kick. By now the Blues supporters had had enough of the referee George Clancy who seemed to be penalising the Blues for no apparent reason.
Glasgow turned the ball over and broke from their twenty two with Evans, Stortoni and Parks inter passing well. However, Gavin Evans had tracked back to prevent the try but the Blues were again penalised and Parks converted.
Cooper broke down the right and put in a neat chip before driving Stortoni back into his own twenty two and Glasgow cleared. It was a rare glimpse from the Blues in what was a disappointing second half. To make matters worse Glasgow got their second try with breakaway that Jonnie Beattie rounded off touching down under the posts with Parks converting.
It was a disappointing match after last weekends win and there was much work to be done ahead of next weekends Heineken Cup match. However the Blues did get a late consolation try for Sam Warburton.
