Cardiff Blues 3 Glasgow Warriors 18
Peter Horne kicked all of Glasgow Warriors' points as they recorded their fourth triumph in a row by defeating the Cardiff Blues 18-3.
Horne slotted four first half penalties as the Warriors led 12-3 at the interval, with Cardiff's response coming through Leigh Halfpenny.
The visitors then added two more three-pointers for the only scores of a disappointing second period.
Last season's play-off semi-finalists Glasgow opened the campaign with two defeats, but three successive victories has seen them get back on track.
Despite a raft of injuries, the Warriors have performed impressively over recent weeks and they managed to control the opening stages of this encounter effectively.
In fact, their set-piece dominance enabled them to build pressure on the Blues' defence.
The hosts held out until the 17th minute when Horne slotted his first penalty of the half before he kicked another soon after.
Cardiff were simply struggling to get into the game and they drifted further behind through the deadeye boot of the visiting centre.
Horne then added his fourth from the tee to take the visitors 12-0 ahead, but the Welsh side finally registered on the board through Halfpenny.
The second period continued in the same vein as the Glasgow kicker took his chances with consummate ease.
Two further three-pointers extended their advantage to 15 points and, although the hosts' full-back looked to have reduced the arrears with a try, the ball was adjudged to have been knocked on, which ended the Blues' challenge.
