It was Tothe who took over at point guard when Gore went to the bench with four fouls.
Instead of wilting, the Wildcats (16-9) took off on a 13-3 run to start the fourth quarter with Tothe scoring five of those points. That all but determined the outcome as Princeton never got closer than seven.
"I'm like the mother out on the floor," Tothe said.
"If I lose my head we'll all lose it."
It is the first state tournament game victory for Logan.
Princeton did not make it easy in spite of shooting just 29 percent for the game.
"We've had a few games where we shot 29 percent but were able to pull it out," Ball said. "This is a never say die team."
Akers, who came into the game averaging 25 points per game, finished with 17 points and nine assists, but hit just 6-of-30 shots.
"Krya Cline may have only taken two shots," Logan Coach Kevin Gertz said. "But look at the defense she played on Akers."
Gore hit 12-of-21 shots including 3-of-5 from 3-point range. Mitchell dropped in 8-of-13 shots while playing 32 minutes.
Next is a semifinal meeting at 5:30 p.m. today with top-seeded Spring Valley.
The Timberwolves earned a hard-fought 68-67 decision in the sectional final. In that game Logan turned the ball over while inbounding it underneath its own basket with 6 seconds to play.
"We all think (Spring Valley) is the top team in the state, well maybe," Gore said. "It won't be easy."
Gore had 36 and Mitchell 18 in that contest. Madison Morris has 22, Sarah Kelly 12, and Brooke Heck 10 for Spring Valley.
"I'm looking forward to playing my old buddy Bo Miller," Gertz said of the Spring Valley coach.
