Scarlets, London Irish and Saracens all claimed maximum points in round two of the LV= Cup on Sunday.
For Scarlets, it was their second full house in as many weeks, building on from their victory over Leinster last time out, as Nigel Davies' youngsters once again did the business.
The fourth try proved crucial for London Irish as their 39-23 win was enough to climb past Leicester to the top of Pool 2.
Saracens bounced-back from a disappointing start to the competition to get their campaign back on track with a comprehensive win over Exeter.

At Cardiff City Stadium
Scarlets came out on top Sunday's all-Welsh battle against Cardiff, with the visitors securing a comprehensive 30-3, their second bonus-point win of the LV= Cup.
The Blues had no answer to the onslaught from Scarlets as they went down four tries to nil, with a penalty from Rhys Patchell the home side's lone contribution to the scoreboard.
The visitors made their presence felt early on, with centre Adam Warren dotting down in just the fourth minute.
Kirby Myhill made it two tries inside the first quarter when he crashed over in the nineteenth minute after a cute dummy. Fly-half Aled Thomas was unable to add the extras, but having converted Warren's try and added a three-pointer in between, Scarlets were on the charge.
Patchell added a penalty on the half hour mark and that concluded the scoring for the half, with the score 15-3 at the break.
With both sides failing to make the most of opportunities, the score remained the same until the 67th minute when replacement Richie Pugh crossed for Scarlets' third try. The try came following a sustained period of pressure after Scotland centre Sean Lamont had taken a quick tap penalty in a kickable position
With Cardiff spirits broken, Kieran Murphy grabbed the crucial bonus-point try to add to Cardiff's misery.

London Irish 39 - 23 Newcastle Falcons
At Madejski Satdium
Winger Adam Thompstone scored a brace as London Irish claimed a bonus-point win over Newcastle.
Boosted by the return to action of England internationals Delon Armitage and Shontayne Hape, the Exiles ran the ball with great gusto.
Both teams signalled their intention to play an expansive game early on and it was the Falcons who opened the scoring through a try to centre Jamie Helleur.
Thompstone scored his first try five minutes later after good work from number thirteen Jonathan Joseph.
Newcastle began to lose their discipline in the second quarter and they were made to pay for it with Steve Shingler slotting three penalties in the final fifteen minutes of the first half.
The Falcons responded after the break when Greg Goosen dived over after good work from the backs.
Fly-half Jeremy Manning added the conversion and a penalty a minute later to give the visitors the lead but going behind appeared to spur the home side into action.
Replacement number ten Daniel Bowden put the home side back in the lead with a penalty in the 55th minute before Delon Armitage crossed over in the corner to extend the Exiles' lead.
Bowden put over a drop goal before he was the beneficiary of a barnstorming run from Hape who put the replacement through for a five-pointer.
Bowden was not yet done, putting in a cute little grubber kick that was collected by Thompstone, the winger picking up his second try.
With the result - and the bonus point - in the bag, Irish conceded a late consolation try to replacement hooker Joe Graham.

Saracens 43-20 Exeter Chiefs
At Vicarage Road
Fly-half Owen Farrell put on a stunning performance, scoring a try, creating two more and kicking 23 points, as Sarries bagged a bonus point.
Farrell's pinpoint kicks into the corner also set up Saracens' first two tries after the English champions twice opted to kick for position, rather than go for goal.
Centre Adam Powell, winger Joe Maddock and replacement lock Hugh Vyvyan scored the other Sarries' tries while Exeter replied with tries from lock Chris Bentley and full-back Myles Dorrian. Fly-half Gareth Steenson kicked their other 10 points.
Sarries in led 17-10 at half-time.
