Wales international Alex Cuthbert scored a hat-trick of tries as the Cardiff Blues thumped Edinburgh 38-13 at the Cardiff City Stadium.
Although Phil Godman opened the scoring for the visitors, tries by Lloyd Williams and Cuthbert gave them a comfortable 12-3 half-time lead.
Godman added a drop-goal in the second period before further scores from Cuthbert (twice), Luke Hamilton and Josh Navidi sealed the five points, despite a late Harry Leonard touchdown for the visitors.
With nothing to play for in the league and a Heineken Cup semi-final against Ulster next week, the Scottish outfit decided to rest the likes of Ross Ford, David Denton and Tim Visser, as well as other key first choice players.
Edinburgh took a surprise lead through the boot of Godman, but Cardiff, who are also out of the play-off picture, hit back after 18 minutes.
Good work from Casey Laulala got the hosts to within inches of the line before Williams touched down from close range. Blair converted as they started to dominate a weakened Edinburgh side.
It was therefore no surprise to see the Blues go over just before the break through Cuthbert. With their first foray into the Cardiff half in the second period, Godman scored a long-range drop-goal to reduce the deficit to six points.
But, after John Houston had been sin-binned for the Gunners, the hosts' right-wing displayed his pace and power to shrug off the attentions of two tacklers and scamper clear.
Hamilton powered across the whitewash for the bonus-point before Cuthbert touched down for his hat-trick. Blair added the extras to both tries as the Blues opened up an unassailable 31-6 advantage.
Edinburgh's Leonard then went over for a consolation score. However, Navidi crossed the whitewash for Cardiff, Blair converting, to complete the rout.
