Josh Adams scored a hat-trick of tries as reigning Six Nations champions Wales thumped Italy 42-0 at the Principality Stadium.
Despite their dominance in Cardiff, last year's Grand Slam winners had to wait until the 76th minute to secure their bonus point in new coach Wayne Pivac's first game at the helm.
Italy have now lost 23 consecutive Six Nations matches, and the result was never in doubt in the Welsh capital.
Wales out-half Dan Biggar put early points on the board with a fourth-minute penalty, before adding a second in the 11th minute.
Biggar scored his third penalty five minutes later, before an excellent move set up Adams to go over in the corner soon afterwards.
The subsequent conversion was missed by Biggar, but Wales scored their second try on the half hour mark.
Adams crossed the whitewash for the second time in 12 minutes after a sumptuous thrown assist from the influential Biggar; the Northampton slinging the ball backwards through his legs to find Adams in the corner.

Biggar converted on this occasion, extending Wales' lead to 21-0.
The hosts had to wait until the 59th minute for their next score, with Nick Tompkins cleverly evading several Italy defenders after a good break from Cory Hill. Biggar converted once again.
It was George North who finally sealed a crucial bonus point for Pivac's men.
The 27-year-old, who had seen an earlier try ruled out for a knock-on, crashed over from close range after being set up by Alun Wyn Jones.
Adams crossed the whitewash in the 80th minute to complete his hat-trick, scoring Wales' fifth try in an emphatic home performance.
Leigh Halfpenny converted to cap off a 42-0 win, Wales' third largest win in Six Nations history.
