Sunapee — Every time the Sunapee High girls take the basketball floor, they are instructed to take each game like there could be no tomorrow. They have been doing that for the last 70 games, all of which they have won.

They had one of those no-tomorrow games on Friday night in the NHIAA Division IV quarterfinals at Sherburne Gym against Woodsville.

And the Lakers, as they have for so long, showed there will definitely be a tomorrow as they stormed their way to an 83-18 win over the Engineers to advance to the semifinals against Littleton Monday night at Plymouth State University. Littleton, the No. 4 seed, was a 66-42 winner over No. 5 Nute in its quarterfinal.

Littleton and Sunapee have a history. Last year, the Lakers trailed the Crusaders by more than 20 points in the D-IV final and came back to win, 66-62. It was Sunapee’s second consecutive title.

“We play it like it’s our last game,” said Sunapee senior Faith Larpenter.

Sunapee, which has not scored fewer than 54 points in a game this season, led 56-9 at the half. Friday night’s final tally matched a Laker season-high.

“They are coached well, with fantastic kids,” said Woodsville coach Russ Wilcox.

Wilcox didn’t make any excuses. Still, it didn’t help that Woodsville entered the game without two starters, Alyssa Prest and Courtney Derrington, lost to the team — Prest with a knee injury and Dennis with the flu.

While the Lakers have captured the attention of the New Hampshire basketball world, it is not like wining basketball games is a new thing for the Sunapee girls. They previously won state titles in 2005 and 1994 and lost in the finals in 1993, 1997 and 2014.

Still, Sunapee coach Tim LaTorra keeps getting surprised by this club. “Collectively, it was the best game we played all season,” he said. “The energy and focus was right on.”

“We just try to stay motivated,” Larpenter added.

While Katie Frederick rightly so gets most of the spotlight, sister Meg ignited the Lakers right out of the gate. In the first five minutes she was a real nuisance to the Engineers with three steals, a blocked shot and two assists.

Wilcox took three timeouts in the first five minutes, but with the Lakers pressing and the Frederick girls (with 6-foot-3 Katie playing with arms extended at the top of the press) defending, it was 23-3 with still three minutes left in the period. Wilcox would end up using his allotted five timeouts before the half.

Katie Frederick, who had 36 rebounds in the 2015 championship game, had 18 points to go with 11 rebounds by the half. She would finish with 23 points and 14 rebounds. Frederick sat out a lot of the second half, and the fourth period was played under the running-time mercy rule.

Frederick also stepped back once and made her only 3-point attempt. Larpenter had two from outside the arc. In all, the Lakers had 36-8 edge in field goals.

Larpenter finished with with 10 points, as did Sydney Clark. Jessica Parsons also made her presence felt with a 14-point game. In all, 10 different Lakers scored.

Lily Kinder, who averaged 13 points during the season, had a 10-point game for the eighth-seeded Engineers, who finished 12-8 in league play and 13-9 overall.

Both teams could have shot better from the foul line. Sunapee was 8-of-20 and the Engineers were 2-for-11.

Sunapee, the top seed, will take a 20-0 record into the semifinals. The Lakers haven’t lost a game since falling to Hinsdale, 48-35, in the 2014 state final.
