Newcastle: (13) 25
Tries: Noon (2), Rudd
Cons: Flood (2)
DGs: May, Flood
Scarlets: (6) 9
Pens: C Thomas (2), B Davies
Newcastle kept alive their EDF Energy Cup hopes with a convincing win over Llanelli Scarlets at Kingston Park.
The impressive Toby Flood and Jamie Noon midfield partnership stole the headlines, Noon scoring a try in each half and Flood kicking seven points.
But it was the dominance of the Falcons forwards that thwarted the Scarlets, controlling possession in poor weather.
The visitors managed penalties from Ceiron Thomas (2) and Barry Davies, but a late John Rudd try crowned the win.
We handled the conditions better and didn't play in our own half at all
Man-of-the-match Toby Flood
The Scarlets are likely to have to win at Sale to make the semi-finals, the Sharks now firm favourites to take the group.
The Falcons started well and their early control in the wind and rain was rewarded with a Tom May drop-goal.
The visitors' usual free-flowing game was stifled, with Deacon Manu struggling badly at the scrum and the line out under pressure, but they hit back with a Thomas penalty and a monster 48m effort from Davies.
Noon's break set up an attacking scrum for Newcastle, and when quick ball was fired out by outside-half Toby Flood it was the England centre who had the pace to drift easily outside Thomas' despairing tackle for the opening try.
When Davies suffered a blood injury the Scarlets took the opportunity to reorganise by bringing Stephen Jones on at outside-half and moving Thomas to full-back, a switch made permanent in the second half.
But it was youthful opposing number 10 Flood who rounded off an impressive first half with a drop-goal to extend the home side's lead to 13-6.
Toby Flood gets to grips with Regan King in midfield
Jones and the always-outstanding Regan King began to orchestrate moves in midfield, but with the physical Newcastle forwards on top the Llanelli side found it hard to capitalise.
Thomas narrowed the gap to four with a 61st-minute penalty, before a dropped Matthew Watkins pass cost the Scarlets dear.
The home side counter-attacked quickly from their own half, and when they were halted in the Welsh 22 they swiftly claimed the breakdown ball.
Man-of-the-match Flood spun the ball across the field where it fell to Noon, who had the power to secure the crucial try.
We've been playing in sunshine all season, but in the wind and rain we got stuffed
Scarlets director of rugby Phil Davies
The Falcons turned the screw with a driving line-out, but after a period encamped on the Scarlets' line James Grindal's try was disallowed as he bumped into his own player.
The Scarlets rallied, but Dwayne Peel's pass from a line-out in the Newcastle 22 was intercepted, and the home side launched a length-of-the-field attack for Rudd to score with the last move of the match.
Man-of-the-match Toby Flood:
"We haven't put in many performances like that this season, we handled the conditions better and didn't play in our own half at all.
"I was pleased with my own performance, but all the lads worked hard, especially the forwards.
"We need to take that sort of display back into the Guinness Premiership."
Scarlets director of rugby Phil Davies:
"That was the poorest we've played all season. We've been playing in sunshine so far, but in the wind and rain we got stuffed.
"Newcastle were terrific, but we do have a power game and a kicking game - we just didn't show it.
"It's all about learning, we'll pick ourselves off the floor and go again.
"We can win at Sale, but we have the Heineken Cup to concentrate on first."
