COEUR d'ALENE - Junior guard Madison Sumner is known mostly for the lockdown defense she plays for the Coeur d'Alene High girls basketball team.

But her biggest play Tuesday night might have come on the offensive end as the Vikings, ranked No. 3 in 5A, handed the top-ranked Post Falls Trojans their first loss, 47-41 in 5A Inland Empire League play at Elmer Jordan Court.

Moments after the person she guarded so well most of the night, Hallie Gennett, stuck a 3-pointer from the right wing to tie the game at 39 with 2:32 left to play, Sumner sank a 3-pointer from the top of the key with 1:55 left to put Coeur d'Alene (13-3, 2-1 5A IEL) ahead to stay.

"Normally, to be honest, I'm not a shooter," Sumner said. "I just decided I was so angry at that point, if she's going to score against me, I might as well score against her. And that's normally my spot where I can shoot a 3 if I do shoot. I think it got the team pumped up ... and it really got us going."

Post Falls fell to 15-1, 2-1.

In the boys game, Coeur d'Alene (8-3, 1-1) took control with a 12-0 run to end the first quarter, then held off a fourth quarter rally by Post Falls (5-7, 0-1) for a 64-52 victory.

Coeur d'Alene's boys and girls travel to Lake City on Friday for the Fight for the Fish spirit games. Post Falls' girls return to action Jan. 18 at home vs. Lake City. Post Falls' boys travel to Moscow next Tuesday.

Coeur d'Alene 47, Post Falls 41: Post Falls had won its first 15 games by an average of 28.1 points, with only one win by less than 13 points.

But Coeur d’Alene delivered an early blow, jumping out to a 12-0 lead after 5 1/2 minutes. The 5-foot-7 Sumner, Sydney Williams and Caelyn Orlandi each scored four points during that run, mostly fueled by defense.

“To get a lead is kind of nice, isn’t it? ” Coeur d’Alene coach Dale Poffenroth said. “Because they’re so good. They’ve got so many weapons, and they’re so strong, and quick, a cushion is pretty nice to have. Can we get that again? I don’t know.”

“I did not see that coming at all,” Post Falls coach Marc Allert said of Coeur d’Alene’s early run. “I thought with the seniors we had, and all the games they had played, that we’d come out ready. We just didn’t make shots. Obviously you have to give Coeur d’Alene credit, they made things difficult.”

The Trojans spent the rest of the game battling back. The 5-11 Gennett scored Post Falls’ first basket on a drive to the hoop with 1:34 left in the first quarter. Coeur d’Alene led 18-4 midway through the second quarter before the Trojans came within 20-9 at halftime.

Dani Failor’s putback right before the buzzer pulled Post Falls within 32-28 after three quarters. The Trojans tied it for the first time when Gennett came off a baseline screen from Failor, took a feed from Brooke Litalien and stuck a 3 from the right wing.

After Sumner’s 3, Gennett sank two free throws with 1:45 left, but Post Falls never scored again.

The Vikings lost junior guard Sydni Parker to an ankle injury late in the first half. But junior Brittany Tackett stepped up with eight of her 10 points in the fourth quarter.

Williams finished with 14 points, seven rebounds and three assists for Coeur d’Alene. Sumner added 12 points and Kendalyn Brainard chipped in seven rebounds and three assists.

Failor had 12 points and 10 rebounds for Post Falls, and Gennett finished with 11 points.

Sumner said she knew from the beginning of the season that she would be guarding Gennett when the two teams finally matched up.

“She’s a lot bigger than me,” Sumner said. “So it’s very difficult. I was very tired, but I just told myself, ‘we’re going to beat them, and I wasn’t going to give up.’ My goal was to not let her score — obviously she was going to, but not to the extreme that she had been in other games.”

The teams play again Jan. 25 at Post Falls, then could meet again at the Region 1 tournament and possibly at state.

“As good as these two teams are, I don’t think that one can beat the other four times,” Poffenroth said.

“Everything’s still within the grasp of what we want to do,” Allert said. “It’s one game. To play as bad as we did, and still make it close, we’ll be all right. It’s not the last time we’re going to see them, that’s for sure. And they’re all going to be a battle.”

Coeur d’Alene 64, Post Falls 52: Devin Kluss dunked, was fouled and hit the free throw to boost the Vikings’ lead to 42-26 with 3 minutes left in the third quarter. Coeur d’Alene built it up to 48-29 before Post Falls battled back to within 4 before the Vikings held on.

“I honestly think at that point (Kluss’ dunk), our boys thought we’d just won the Super Bowl,” Coeur d’Alene coach Kent Leiss said. “We talked about being patient, but we took turns taking bad shots, taking ill-advised drives to the basket, and it kind of infected the team. We made a lot of poor choices in the last 10 minutes of the game.”

Justin Carpenter led a balanced Viking attack with 12 points, and Colby Daniels added 10.

Post Falls pulled within 54-50 on Corey Koski’s layup with 2:52 to go. But Kluss beat the press for a layup moments later, and the Vikings were able to stave off the Trojans.

Dalton Thompson scored a game-high 19 points for Post Falls. Koski added eight points, seven rebounds and five steals off the bench, and Tim Mueller had eight points, six boards and three blocked shots.

But Post Falls shot just 7 of 31 from the field in the first half, and made just 12 of 28 free throws for the game.

“It’s hard to learn how to win on the road when we don’t shoot exceptionally well in the first half,” Post Falls coach Mike McLean said. “You can’t win on the road in the IEL if you don’t make your layups, and we missed way too many free throws. I think Coeur d’Alene’s physicality at the guard spot just took us out of what we wanted to run.”
