Leinster’s forwards were in seventh heaven after breaking their previous try-scoring record in yesterday’s RDS try-fest.
No Blues back got on the scoresheet against the Scarlets as the pack surpassed the League record set by the province in 2013.
Johnny Sexton came off with a hip flexor issue in the 61st minute and will be assessed, although Blues supremo Leo Cullen is optimistic the Leinster and Ireland skipper will be OK.
“He was happy in the dressing-room, happier than he looked (coming off),” smiled Cullen, after watching his side rack up the half-century against a Scarlets side who shipped 43 points at home to Munster last week.
James Ryan, however, could miss the province’s last game of this block of URC fixtures away to Glasgow next week.
Ryan went off for a HIA with just over 10 minutes to go and will go through the gradual return protocols.
The visitors scored the first try of the game in the eighth minute through Johnny McNicholl but were 22-8 behind at the break as returning Lions Ronan Kelleher, Jack Conan and Tadhg Furlong in particular wreaked havoc.
Tries by front rowers Kelleher and Porter put the hosts in the ascendancy before massive pressure on the Scarlets’ line saw the ref Marius van der Westhuizen award a penalty try to finish the half.
The bonus point followed seven minutes after the restart when Caelan Doris was in the perfect position to finish Kelleher’s superb run. With Sexton feeling his hip, Ciaran Frawley nailed the conversion.
The impressive Frawley and Gareth Davies suffered an accidental but nasty head collision moments later, but while the Leinster centre went for a HIA he was able to return later.
Tomas Lezana grabbed a second try for the Scarlets.
But that proved only a temporary respite and further tries followed for the home side in the closing stages from front row replacements Cian Healy and Dan Sheehan – the latter with the final two of the game.
