Centre Aled Summerhill helped himself to a hat-trick as reigning champions Pontypridd punished Llanelli at Parc y Scarlets.
Ponty ran home 11 tries in a crushing win with No. 8 Jake Thomas and wing Lewis I Williams also bagging braces.
The game was effectively over as a contest by half-time after a stunning display of attacking rugby saw Ponty score six first-half tries to lead 30-3, before adding five more in the second half.
The scoreline would have been even more convincing had fly-half Simon Humberstone not missed his first eight conversion attempts.
Wing Richard Thomas and flanker Owain Morgan replied for Llanelli but they had no answer to the visitors' power.
It was a 16th win in 17 games for Ponty as they continue their march towards another Principality Premiership title, while Llanelli — who already looking towards next season — remain ninth in the table.
Fly-half Billy McBryde kicked the hosts into a second-minute lead, but it was the visitors who got the first try of the game after five minutes following a scrum, with Thomas scoring.
Ponty got their second try two minutes later when Summerhill received the ball wide on the left and stormed through to the line.
The third try arrived after 17 minutes when Humberstone's kick landed in Owen Jenkins's arms and the wing did the rest.
Ponty secured their bonus point on 22 minutes when Lewis I Williams went over after Humberstone's initial burst towards the line was held up.
Summerhill went over for his second try four minutes later as Ponty stated to run riot and hooker Aled Morris added try number six before the break.
To their credit, the hosts responded with an unconverted try of their own straight after the break through Thomas, but Lewis I Williams soon went over for Ponty's seventh unconverted try.
Thomas added his second, while replacements Dafi Davies and James Howe also got in on the act before Summerhill completed his hat-trick with Humberstone adding three conversions.
Morgan scored a late unconverted try for the home side, but it was scant consolation.
