Glasgow Warriors won for the first time on the road in the Magners League since April as Thom Evans and Johnnie Beattie touched down in a 21-5 triumph over Cardiff Blues on Saturday night.

Glasgow claimed their first ever away victory over the Blues in a game which was dominate by penalties and turnovers.

After Dan Parks had put the visitors in front with the first of the penalties, it was Cardiff who looked the more fluent, with winger Richard Mustoe and number 8 Andy Powell causing problems.

But basic mistakes repeatedly cost them attacking positions and it was Parks, in a rare Glasgow foray downfield, who doubled the lead with another easy kick from in front of the posts.

Another tremendous charge by Powell earned the Blues a rare penalty of their own, but Leigh Halfpenny, in at full-back instead of the injured Ben Blair, was off target with the kick.

Glasgow were putting boot to ball to good effect and their varying skills in that department brought a try to end the first half.

A huge up-and-under from full-back Bernardo Stortoni was fumbled by Blues scrum half Gareth Cooper, the Warriors claimed possession and Parks delivered a neat chip for Thom Evans to touch down.

The Scottish fly-half was proving less adept with place-kicks, however, pushing the conversion wide and then hitting a post with a penalty to open the second period.

Losing their way in attack, the Blues were turned over and Glasgow looked certain to score, only for centre Gavin Evans, making his first start since arriving from the Scarlets, to produce a try-saving tackle on Parks.

Another penalty followed and this time Parks made no mistake.

A gallop by lively Warriors flanker Richie Vernon might have brought a score, had he not opted to ignore the unmarked Dave McCall. But if the visitors could not create a try of their own, they could rely on the Blues to do it for them.

Once more they spilled the ball in the Scots’ 22 and Thom Evans broke clear to send number 8 Beattie under the posts and provide Parks with a simple conversion.

A late try by flanker Sam Warburton merely enabled the Blues to avoid a whitewash, and a last-minute yellow card for a high tackle by Glasgow replacement Calum Forester made little difference to the result.
