In Class AA sectional play, the Tug Valley High School Lady Panthers advanced to the winner's bracket of the tournament yesterday with a forfeit win over Mount View.
The Lady Panthers will now play tonight at Tolsia High School in the double-elimination tournament.
"I didn't figure Mount View would show up," Tug Valley Coach Vonda Preston said yesterday morning in a phone interview with The Logan Banner. Tug would have to lose two matches to be eliminated from the sectional tournament.
Two teams — the winner and runner-up — will advance to the regional tournament from the section.
