Harlequins' chief executive Mark Evans has been forced to reconsider his opinion that Worcester's scrummage is the second-best in the Zurich Premiership.
Evans spent Saturday afternoon watching his pack shunted to all corners of The Stoop by a superb Warriors' octet who gave their teammates the platform to take four crucial top-flight points.
The 15-9 win, Worcester's sixth in the league, lifted them to ninth position in the table and six points clear of last-placed Northampton, who were yesterday routed by Wasps.
The Warriors' conservative forward-orientated display was not easy on the eye but it was hugely effective and it made Evans think again.
"We said before the game that we thought they were the second-best scrum in the league after Leicester. After today. I might have to revise that opinion," he said.
"We got scrummed out of the game. We have scrummed pretty well all year but all credit to Worcester they scrummed very, very well on both sides. They did us and you have got to hold your hands up."
The praise is only magnified when the Worcester and Tigers' packs are compared. While Leicester's is stuffed full of internationals and British Lions, Warriors' forwards are a lot less illustrious.
The runaway Premiership leaders can field a pair of England internationals Graham Rowntree and Julian White in their front-row and another pair in World Cup winners Martin Johnson and Ben Kay behind them.
Their back-row consists of Neil Back and Lewis Moody, also world champions, while the only international in the Worcester eight is skipper Pat Sanderson.
But then scrummaging is rather more about power than it is profile and Worcester have that in abundance, as they proved in two contrasting 40-minute periods against 'Quins.
"In the first-half, we established scrum positions in the right areas of the pitch and they gave us all sorts of problems on our own put-in," Evans said.
"In the second-half, when they had the ball, they did a lot of double-driving. That last scrum at the end took around four-and-a-half minutes to actually end up in something.
"The scrum is a key part of the game and they used it really well in both halves to do different things. It is a tough game when your scrum isn't working on both sides of the ball."
Worcester's next potential victims are Sale Sharks, who arrive in the Midlands on Friday night shorn of nearly half of their team after international call-ups.
If Worcester could avenge September's 57-3 humiliation in the reverse fixture, it would virtually guarantee their Premiership status.
