CLASS D SOUTH GIRLS

MADISON 42, CARRABEC 34: Jaelyn Rich and Ava Landry each scored nine points and the sixth-seeded Bulldogs upset the Cobras in a Class D South quarterfinal at the Augusta Civic Center.

Leah Harper and Dakota Estes each added eight points.

“They’re pretty happy,” Madison coach Adam Rich said. “It’s always nice to beat a rival, too. They’re right next door to us. It’s a really big game for them.”

Madison (10-9) used a 16-4 run in the first half to erase a seven-point deficit, then kept the lead for the rest of the game with a disruptive high-intensity press defense.

“We were stressing a little bit, but we just talked about it, got composed and went from there,” said Landry, who added six rebounds and three steals.

“We gain our energy from our defense,” Rich said. “In the first quarter, we weren’t really getting to our spots, getting to the help side as much, then when we were getting hands on balls, the energy starts feeding into it, it’s more of a better thing when we play uptempo.”

Carrabec (15-4) made it a two-possession game multiple times late in the fourth quarter, including 36-32 with 1:25 left, but Madison went 4 for 8 from the free-throw line to close it out.

Carrabec senior Anna Canales led all scorers with 14 points.

BUCKFIELD 61, BOOTHBAY 37: Chloee Bennett scored 18 points and Alyssa Breton added 17 as the second-seeded Bucks rolled past the seventh-seeded Seahawks (5-14) and into the Class D South semifinals.

Buckfield (16-3) will play No. 6 Madison at 10 a.m. Thursday.

Boothbay went up 6-2 in the first two minutes, but the Bucks closed the quarter on a 17-4 run.

Tatum French led Boothbay with 18 points, including all 12 in the final quarter.

Sarae Devoe scored 13 points for Buckfield.

MONMOUTH ACADEMY 49, OLD ORCHARD BEACH 35: Kaitlyn Frost dropped in 15 points to go with three steals, and the fourth-seeded Mustangs (11-8) never trailed the fifth-seeded Seagulls (12-7) in a Class D South quarterfinal.

Monmouth opened the game on a 12-0 run. Old Orchard Beach pulled to within one point, but the Mustangs broke it open again with a 24-4 run that carried into the second half.

Peyton McDonald scored 11 points for the Mustangs. Maeve Burgess added nine points and six rebounds.

Reagan Partridge led the Seagulls with 19 points and nine rebounds.
