But the Lady Bearcats looked like high school playoff veterans on Wednesday night, routing Potosi 60-40 in a Class 4 Sectional game at Mineral Area College in Park Hills.
The Lady Bearcats (24-4) raced out to a 10-0 lead and never looked back as they dominated the out-matched Lady Trojans (21-7) in every phase of the game.
Dexter will play St. James (23-5) in a quarterfinal game on Saturday at 6:30 p.m. at the Farmington Civic Center.
"I'm just really thrilled to death that the girls came out on fire," said Dexter coach Gavin Miller. "Offensively we were patient early. But man, we just played good defense from that start. We're going to celebrate tonight and then get back to the drawing board tomorrow."
Dexter was never threatened on Wednesday, taking a 17-3 first quarter lead and a 28-7 lead at the half.
Potosi didn't score until the 3:13 mark of the first quarter.
During Dexter's 10-0 lead, junior forward Taylor Nelson buried two 3-
pointers right off the bat.
They were the only two shots from downtown that Dexter would hit, but it opened up the middle for Dexter's inside players.
"I knew they were going to sag in that zone a little bit because they've probably seen and heard that the Lady 'Cats don't shoot outside very well," said Miller. "But tonight we shot the ball pretty well everywhere."
The Lady Bearcats led 22-3 before Potosi scored its next points, that being two free throws by Julie McGirl with 4:49 left in the half.
Dexter eventually built a 28-5 lead just before halftime before Tiffany Owens connected on two free throws with five seconds left.
Potosi simply couldn't buy a basket in the first half as the rim seemed to have a lid on it.
Many shots were point-blank looks, but even those wouldn't fall.
Potosi had just one field goal the entire first half. In addition to that, Dexter's full-court press caused numerous turnovers.
"We couldn't shoot early, for one thing," said Potosi coach Matt Bradley. "We missed some chippies early that would've kept us right in the game. But once we spotted them their 15 or 18, it was pretty well even after that. But you can't do that with teams like Dexter -- they're too good.
"We had to keep them from getting a big run on us early and we just weren't able to do it."
Potosi settled down a bit in the third quarter but they still couldn't stop Dexter on offense.
The Lady Bearcats led by as much as 39-13 with 3:37 left in the third quarter.
Potosi was able to cut the lead to 43-19 at the end of three.
The Lady Trojans actually outscored Dexter in the fourth quarter but the lead was never threatened.
Potosi started the quarter on a 10-2 run to close the gap to 45-29 with 6:13 to go, but Dexter scored six straight points to assure the comfortable victory.
"We've got a mark on our board at home that if we know we can keep a team under a particular amount of points then we're going to win every game," said Miller.
"But I'm not going to tell you what that number is until after the season."
Dexter all-state forward Rachel Blunt pumped in a game-high 23 points. She shook off getting her shot blocked by Potosi's 6-foot senior Lora Dickey on her first two attempts of the night.
"I told (Blunt) before the game that you're going to have to pump-fake," said Miller. "Either pump-fake or take it to the basket hard. She really kind of took over the game after those first couple of shots."
Blunt scored most of her baskets on drives to the hoop.
"We let her slide into the post on us," said Bradley.
"My wings weren't very good on our 2-3. She's just an awful good player. She's going to get hers."
Dexter also got a big scoring night from sophomore Haylee Finch, who scored 14 points.
Nelson added 10 points before fouling out.
Dickey led Potosi with 17 points.
