LETHBRIDGE, ALTA. - Super sub Melanie Robillard continues to get the job done.

A week ago, Robillard was working as an office manager for a hedge fund in Madrid.

Then, when German skip Andrea Schoepp broke her leg in a skiing accident last Saturday, the call went in for the Canadian-born curler to step into the lineup.

Robillard, third on the German team that won the 2010 world championship, found out the day before the women's world championship started that the team wanted her to skip.

So far, so good.

While Robillard calls the game, Imogen Lehmann, who stepped into Robillard's position when she moved to Spain last year, is throwing last rocks.

The team started the week with two straight wins, including a 7-6 extra-end verdict over pre-event favourite Eve Muirhead of Scotland Sunday morning.

"There is no secret," said Robillard. "We had pretty good control of it all game and it was pretty steady. Imogen played amazing, she had good draw weight and she could bail us out when we needed it.

"I was pretty confident on the last draw. She'd had pretty good draw weight all game. And she's a pretty calm person."

Robillard said she's had several conversations with Schoepp, who's recovering in Germany after undergoing surgery Sunday. That's helped her understand the tendencies of the young supporting cast.

"I'm sure she's really proud," Robillard said of Schoepp. "I've talked to her. It's new for me, learning how the girls release it and throw, so I'm having chats with her on a daily basis to see how she can help me. I'm still really new at this."

Robillard also credits Lehmann with helping her keep calm during a stressful and unusual transition.

"She's a really calm person and that helps because I'm a bit more on the hyper side," said Robillard. "She calms me down and it works really well."
