HEAD coach Carl Hogg admits Worcester Warriors need to “tidy up” their set-piece at Birmingham Moseley tomorrow night (7.30pm).

Warriors won 55-21 in their pre-season opener against Championship side Hartpury last Saturday.

Dean Hammond (3), Matti Williams (2), Josh Adams (2), Pierce Phillips and Tom Howe scored in the nine-try thrashing.

But Worcester came under pressure at times, conceding three converted tries, and Hogg felt his players needed to brush up on the new law changes to gain an advantage in the scrum.

Under the amendments set out by World Rugby any front-row player from the team who have put the ball into the scrum can use either foot to try to win possession.

Another change allows the scrum-half to align their shoulder on the middle line of the scrum, meaning he is closer to his own side.

But the ball must be thrown in straight and there will be no signal from the referee to feed it in.

There is also an exception to handling in the scrum where the number eight can now pick the ball up from the feet of the second rows.

“First time out it always tends to be about blowing the cobwebs away,” said Hogg whose team kick off their Aviva Premiership campaign on Friday, September 1, at Newcastle Falcons.

“Regardless of how hard you work in training and how lively you are in sessions a match is a very different stimulus.

“You get a real feel for the areas you need to work on and I must give Hartpury credit as they were very physical, especially in the first half.

“But once we kept the ball in hand and wore them down our quality told.

“We need to tidy up some of our continuity with our set-piece work though.

“There has been a law change around the scrum and engagement so we have obviously got to look at that more closely as we go into the season.”

Warriors fielded two different sides against Hartpury in a bid to give players game-time.

Hogg confirmed he would do “something similar” at National One side Moseley before looking ahead to their friendly against Munster at Sixways next Thursday.

“The Munster group of 25 or 26 players will be much more like what will roll out against Newcastle in the Premiership,” Hogg said.

“But at the moment we want to give opportunities for players.

“We have got a big squad of 42 and everybody needs to feel they have got an opportunity so we are looking to do something similar against Moseley.

“It will be exactly the same exercise and then we will narrow that down the following week.”
