There are logjams atop the men's and women's standings at the world junior curling championships with both Canadian skips in the mix.

Edmonton's Brendan Bottcher defeated the Czech Republic 9-5 on Wednesday to improve his record to 6-1 and remain tied with Norway atop the men's draw.

On the women's side, Jocelyn Peterman of Red Deer, Alta., split her two games to remain in a three-way tie for first at 6-2.

Bottcher now has his eye on the playoffs but doesn't want to get to ahead of himself.

"That's definitely one step closer, but we've still got a couple more games to go and we can keep it in our own hands if we just do what we need to do," he said. "I feel like we're getting stronger each game and hopefully we can keep doing that and growing into it."

Playing just one game Wednesday, Bottcher opened with a single in the first end against the Czechs and followed that up with a steal of two in the second end. He then scored deuces in each of the fourth, seventh and ninth ends.

Norway edged the U.S. in an extra end to stay deadlocked with Bottcher.

Scotland and Sweden are tied for third at 5-2, the Scots defeating Switzerland 8-6 while the Swedes downed Finland 8-4.

Canada closes out the round robin with a game against Finland on Thursday.

Peterman opened her day with a 10-6 win over Russia before falling 7-6 to Japan in the evening draw.

The Russians rallied with a 9-7 win over Sweden in the evening to stay in a tie for the lead along with Canada and the Czechs, who posted two victories on the day, defeating Norway 11-4 and Italy 6-5.

Canada faces Sweden in its final round-robin game Thursday.
