Canada concluded round-robin play in the ISF Women's World Championships with an offensive outburst on Thursday night.

Canada exploded in the second inning, bringing seven runs across the plate en route to an 8-0 win over Italy.

With the score knotted at zero, Jennifer Salling opened up the second frame with a double to centre field.

Caitlin Lever, Canada's veteran centre fielder, then stepped up to the plate and crushed a high arcing shot to right field, her first home run of the tournament.

After that, the Canadians couldn't be stopped.

Italy went through three pitchers trying to slow the bleeding but with Canada adding another run in the top of the fourth, the game was called.

It was a big win for Canada as they will look to carry the momentum into a quarter-finals match up with the United States tonight.

The Americans have been unstoppable in the tournament, allowing only one run and going undefeated in seven games.

A win for Canada would send them directly to the semi-finals. A loss means an extra game on Saturday morning but another opportunity to make it to the semis.

Canada faced the U.S. two weeks ago in the Canadian Open, suffering a 14-2 defeat.

Canada's head coach, Mark Smith, said the team that takes the field tomorrow night will have a whole new look.

"Truthfully we didn't play our better players. We had two or three injuries, our pitching was depleted and that was strategic on our part,” he said.

"We knew we'd get beat up pretty good but as I say to the girls, you don't want to win the battle, you want to win the war and we're here to win the war.”

The Canadian team also has experience on their side this time around.

Daniel Lawrie, Salling and Lever are all recent additions to the roster that were unavailable at the Canadian Open due to commitments to their U.S. based professional teams.

"We've got a little more depth which we haven't had the last couple of summers and that changes the water on the beans a little bit,” said Smith.

"The U.S. has a very inexperienced team internationally. For most of those girls this is their first or second real test whereas we've got seven or eight girls that have played in the Olympics and dealt with this kind of pressure before.”

Jenna Ciara got the win against Italy, pitching a complete game and collecting nine strike-outs. She said the team is looking forward to proving that they're a contender for the gold.

"That's been our mindset the entire time,” she said.

"We want to go for the gold. We've been so focused from warm up the last pitch and

I think if we keep up that mentality we can make it to the gold medal game.”

Sheena Lawrick, Canada's first baseman, collected two RBIs on the night and said it was important to get the offence going in the final game.

"You always want to head into the playoffs with the bats rolling,” she said.

"Our hitting is definitely one of our strengths right now and getting Danielle (Lawrie) and Jenn (Salling) back gives us a pretty good confidence too. They're great players and they add to our strength.

"This is the part that gets gritty and fun so we're looking forward to it.”

Ciara said Canada's ability to consistently generate runs throughout the tournament has led to a well rested pitching staff.

"Our offence has made it extremely comfortable for our pitching, " she said.

"We can trust the bats right now and we're utilizing our pitching staff so everyone's getting the rest they need. When the opportunity comes to get into the circle, we can do our jobs.”

Pitching will be one of the storylines in tonight's match-up with the U.S.

The Americans have one of the top pitching rotations in the tournament and have given up only run in seven games.

"They've got some pitching that can be dominate and we know that but historically we've done pretty well against their pitching,” said Smith, who also noted that the chemistry on the team is the best he's seen in his four years on the bench.

"Our strength right now is our chemistry and our veteran leadership,” he said after the win over Italy.

"Our girls have been here before. There are no surprises tomorrow. There are no secrets, it's the same team, same uniform, same game.

"Tomorrow will be about coming out, putting our best players on the field and playing the best ball that we can and hopefully coming out on the right side of it.”
