Substitute Nikola Matawalu ran in two tries as Glasgow Warriors recorded a convincing 33-12 Pro12 victory at Cardiff Blues on Sunday.
The Scottish side had opened their season with an impressive victory over reigning champions Leinster last weekend, but took time to really stamp their authority at Cardiff Arms Park.
Under the watchful eye of Wales coach Warren Gatland, fly-half Rhys Patchell - a star performer in the Blues' 41-26 win at Zebre a week ago - opened the scoring from the tee in the opening four minutes.
But the men from the Welsh capital proved too reliant on Patchell's kicking and two wayward efforts from six attempts did not help their cause.
Sean Lamont left Patchell for dead as he stormed down the left wing to touch down for the first try of the match shortly after the half-hour mark - Glasgow heading in at half-time with a 13-6 advantage.
The Blues pulled to within a point of their visitors at the start of the second half, but the floodgates opened somewhat thereafter, despite Glasgow prop Gordon Reid being sent to the sin bin.
The hosts carelessly squandered possession to allow Matawalu to charge for the corner, before the Fijian placed his second under the posts.
Duncan Weir's boot contributed 10 second-half points to bolster Glasgow's tally, but Gregor Townsend's men were unable to find the fourth try that would have earned a valuable bonus point.
Leinster bounced back from their opening-weekend defeat to Glasgow by storming to a 42-12 win over Scarlets on Saturday.
Full-back Rob Kearney scored two first-half tries either side of a Scott Wiliiams touchdown, before Ian Madigan went over for this first of his double to send Leinster in at half-time with 21-5 lead.
The fly-half opened the scoring in the second half and tries from Dominic Ryan and Tadhg Furlong, combined with a consistent kicking display from Madigan, saw Leinster stretch their advantage to 37 points.
Johan Snyman's late try for the Welsh region proved to be a mere consolation.
"The squad is moving forward and that's what we're going to need," said Leinster coach Matt O'Connor. "We were disappointed off the back of last week and we put a lot of those things right, which was pleasing."
In addition to Glasgow, Ospreys and Connacht also maintained their 100 per cent starts to the new season.
Ospreys got the better of Newport Gwent Dragons in an all-Welsh clash on Friday - Eli Walker and Rhys Webb touching down for the Swansea-based side in a 17-15 win at Rodney Parade.
Connacht scored eight second-half points without reply in coming from behind to beat Edinburgh in the Scottish capital.
In the round's remaining fixtures, Munster triumphed 21-10 at Benetton Treviso, while Ulster were 33-13 winners over Zebre.
