Missoula, MONT. -

The final week of high school volleyball is upon with the all-class state tournament in Bozeman starting Thursday morning at the Brick Breeden Fieldhouse at Montana State University.

Out of the class 'AA' Western Conference, one team has already pulled off a postseason upset just to make it this far.

Missoula Sentinel enters state this week as the #4 seed from the West. Despite going just 3-9 in league play during the regular season, the Spartans went on the road last week and knocked off Helena Capital in four sets to punch their ticket to state.

"It's unbelievable,” says senior Krista Hunton of Sentinel’s playoff win over Capital.  “We really did not expect to pull that upset but I just really think we went in with a ton of intensity and we really brought what it took to beat that team, so it was just awesome."

Sentinel will have their work cut out for them in Thursday’s opening round when they will have to battle the top-seed Billings Senior, who has only one loss on the entire season. The Spartans are hopeful that their momentum from last week's playoff win can carry over to surprised teams as the underdog in this week's state tournament.

"I think it will bring our confidence up a lot,” says junior Morgan Becker.  “We didn't go in there expecting to win, so I think now we have the attitude that we can do what we want if we put our heads to it.”

"You know we've seen them and they go up and down just like any other team,” says Sentinel Head coach about playing Billings Senior in the first round. “We know they're solid and we have a lot of respect for them but we just have to keep believing."
