Several of Duluth's own were on the sheet Tuesday morning in Omaha playing for a chance to represent the United States in South Korea in February.
In the women's division was Cory Christensen's team.
Christensen's team didn't get off to the best start, allowing three points in the first two ends.
The team tallied points in the 3rd and 5th ends but 4 points in the 6th end by Sinclair's team put Christensen's squad in a big hole.
They retired following the 7th end after trailing 9 to 3.
"We just came out a little flat this morning and I think if we play like we did our first few games, we still have a chance to be in the mix of things," said Christensen team captain, Cory Christensen. "We just need to play better. Jamie's team came out and played great so we just need to pick it up."
Christensen's team now sits in third place in the trials with a 1-3 record.
Chisholm's John Shuster was hoping for some separation before the playoff on Thursday.
Both Shuster and Heath McCormick's teams had a 4-1 at the trials record before Tuesday's game.
Shuster's team went down 1 after the first end but bounced back with two points in the 2nd.
They added more deuces in the 6th and 8th to go up 6-2.
Shuster and his team held on 6-5 to move alone atop the men's standings and inch closer to donning the red, white, and blue.
"It's what we dream of, it's what we've worked for and our team's really put the work in the last four years, so to be able to have it culminate with a chance to go to the Olympics is our goal and it always means a ton to wear the stars and stripes," said Shuster.
Shuster and his team need just one more win to advance to the best of 3 playoff on Thursday.
Duluth-native, Chris Plys, is the third for McCormick's team. They're alone in 2nd place with a 4-2 record
