SCARBOROUGH — Seventh-seeded Scarborough took command midway through the second quarter Wednesday and went on to a 51-36 victory against 10th-ranked Marshwood in a Western Class A girls’ basketball prelim.

The Red Storm (11-8) will take on second-seeded Thornton Academy (16-2) in the quarterfinals at 3:30 p.m. Monday at the Portland Expo.

Scarborough tucked the game away with a 25-6 run that began in the second quarter and extended to the end of the third.

“That was where the game was won,” said Scarborough Coach Mike Giordano.

Scarborough controlled both the offensive and defensive boards led by Brooke Malone, who finished with 14 rebounds.

“Five-foot-seven post player and she’s our leading rebounder. That tells you a little bit about who she is,” said Giordano.

Malone fell two points shy of a double-double.

Sophie Glidden and Bailey Adams paced the Red Storm with 14 points each.

“Sophie Glidden, as a freshman, her first tournament game, she really showed herself well tonight,” said Giordano.

For Marshwood, senior Megan McLean had a standout game. She was a force in the first half, scoring 15 of her 19 points and keeping Marshwood in stride with the Red Storm.

Giordano decided to make a defensive switch in an attempt to slow McLean.

“(We) switched out defensively and put (Sam) Sparda on (McLean) and she’s our defensive specialist,” said Giordano. “Megan’s a really nice player and I thought Sam did a great job on her.”

McLean also had two blocks and two steals.

“When things started going bad, we started relying on things more individually. We started settling for jump shots, which we can’t do,” said Marshwood Coach Lee Petrie.

Scarborough led only 28-26 at the half, then outscored the Hawks 23-10 in the second half.

“Great first half up and down, 28-26, and I told the girls that I thought we were going to either win or lose the game on the defensive end, and we held them to 10 (points) in the second half. So … it’s nice when they listen,” said Giordano.

“There were a lot of areas where we came up real short in that third quarter. We just did not execute the way we executed all year long,” said Petrie.

“If it was Dec. 11 I wouldn’t be so upset. But it’s Feb. 11 and now we have to sit at home while they go play at the Expo.”

Thornton beat Scarborough twice this season, 44-29 and 49-42.
