Lark Atkin-Davies
England's hooker has scored FOUR tries in this match!
Again they kick for touch from the penalty, again the line-out turns into a maul, again the number two is the woman with ball in hand, again she bursts from the back to score in the corner.
This time the conversion is too tough for Helena Rowland.

Julia Schell is indeed penalised for a head-up tackle, but with only moderate danger so it's a yellow.
There's no bunker review system here, by the way.

Another blooper from Canada, Sophie de Goede and Florence Symonds both attempt to catch a chip kick from England and get in each others' way.
Fortunately for them, the ball is ruled to have gone backwards.
England 28-12 Canada
Well, what today has proved is even when you're not playing your best, a powerful pack will often bail you out.
Canada have also made too many mistakes, and England have punished most of them.

And they score again, through Lark Atkin-Davies! England's hooker has a hat-trick!

The handling errors have returned early in this second half, the loose ball falls to wing Paige Farries and she streaks away from the England defence, running half the length of the field to score.
The conversion is good, and Canada are back in the contest.

England 21-5 Canada
That was 35 minutes of below-par rugby from the Red Roses, then five minutes of clinical dominance.
England needed a kick up the wherever, and the sin bin for Holly Aitchison and the resulting Canadian try was just that.
A great response from Louis Deacon's team, and they are set fair now. Canada with all the work to do.
Lark Atkin-Davies (con Helena Rowland)
They have the score, and it's Lark Atkin-Davies again!
From the line-out, again England's forwards are too powerful, again the hooker grounds amid a sea of bodies.
Helena Rowland converts, and England are suddenly in total control.

Helena Rowland puts over a conversion Holly Aitchison would be proud of.
England 7-5 Canada
England with their best move of the game, ending in them picking up a penalty in a kickable position.
