Ben Blair provided some welcome class in a scrappy Magners League encounter as Cardiff Blues saw off Glasgow Warriors at the Arms Park.
The New Zealand full-back kicked 12 points, cleared his lines impressively and claimed the Blues' opening try.
Mosese Luveitasau, who looked good in attack but shaky in defence, and Tom Shanklin added the other home tries.
Glasgow were limited to three penalties from Dan Parks, although wing Thom Evans deserved a try for his efforts.
A darting run from Mike Phillips earned Blues their opening points, as a Glasgow defender flopped on the wrong side when the scrum-half was eventually grounded.
That left Kiwi full-back Blair, handed the kicking duties instead of fly-half Nick Robinson, to slot the simple penalty.
A low intensity first quarter was played out in the middle of the park with scoring chances at a premium, but Blair did manage a second penalty for the home side.
The accuracy, composure and patience is lacking a little bit
Blues had enjoyed the better of the possession but were mainly having to play with it in their own half.
When they finally got within striking distance of the Scottish line, Tom Riley drew the Glasgow line before his deft pass sent Blair under the posts for a seven-pointer.
The visitors managed to drag themselves back into contention, however, earning two penalties before half-time and one soon after the restart that Parks kicked comfortably to make it 13-9.
Finding it tough to break down a stubborn Glasgow defence, Robinson sent a steepling kick into the air for Shanklin to chase.
The centre won the jump for the ball and, sucking in Scottish defenders, recycled the ball to his fly-half.
Robinson sniffed the space out right and his floated long pass was seized by Fijian wing Luveitasau who showed a clean pair of heels to the line, Blair again converting.
Glasgow's best offensive options lay out wide in the pace of Evans and the fine angles being cut by Hefin O'Hare, but the visitors struggled to get the ball to the wings with any space to work in.
A third Blues try, Shanklin cutting back against the grain to crash over from close range, made sure of the result, although a fourth try for a bonus point escaped them.
Blues coach Dai Young:
"We're happy with the win but, if we're honest, we probably played better in the two games we've lost.
"The effort, commitment and desire is something that we expect and we've had that in abundance.
"But the accuracy, composure and patience is lacking a little bit and our skill levels let us down."
