PORTLAND — After Oxford Hills took an eight-point lead into the fourth quarter, the Vikings dribbled the ball around the half-court as long as they could to try and escape Wednesday’s Class AA North girls’ basketball semifinal matchup with Portland.

Top-seeded Oxford Hills did hold on, beating No. 4 Portland 47-36 at the Cross Insurance Arena.

Before that final period, the Vikings had endured a strong two-quarter attack from Portland’s Gemima Motema, during which the sophomore scored 11 points and recorded two blocks and two steals to get the Bulldogs within five points.

Julia Colby scored four of her 12 points in the fourth quarter to help Oxford Hills advance to the AA North final against No. 7 Deering on Friday at 2 p.m. The trip tot he regional finals is the Vikings’ fifth in six years.

Colby hit three free throws in the fourth, and Cassidy Dumont hit three more to ice the game.

“They went on a little run, they were packing it in, blocked a couple shots, so we had to make a decision, and I think if we stretch them out and played a little offense that way they’d have to foul us,” Oxford Hills coach Nate Pelletier said. “I wish we made a few more foul shots down the stretch, but Julia is shooting 80 percent from the line so she’ll take the ball any day, and Cassidy shot the ball well, too.”

In the first quarter, Colby and Bailey Whitney scored six points each to help the Vikings set the tone and go on a 10-1 run that resulted in a 17-10 lead after eight minutes.

The Vikings opened up the second quarter with an 8-2 run to spread the lead to 25-12. The main contributor of that spurt was junior Cecilia Dieterich, who scored her first bucket off a great cut down the lane into a layup, then scored quickly again off a steal and outlet pass from Dumont.

Dieterich scored seven points in the second quarter, and Oxford Hills went into halftime with a 30-20 lead.

Portland was paced by the aggressive scoring of Motema, who finished the first half with three rebounds, a steal and six points.

Motema missed the first nine games of the season due to injury.

“When I think of Gemima, I think of her starting the second half of her season,” Portland coach Gerard Corcoran said. “With her injuries and being out the first nine games of the season, right now she’s coming into where she should have been maybe two or three games in.”

Motema continued her hot streak in the third quarter with seven points, two blocks and a steal. The sophomore guard was everywhere trying to drag her team back into the contest.

To counter her scoring, Pelletier spread out the Vikings’ offense and switched the defense to try and force some turnovers.

“We went to some zone, we ran a 1-3-1 zone at one point, so it wasn’t just a one-on-one trying to match up with her because it’s impossible to match up with her one-on-one,” Pelletier said. “When we went to the zone it helped everybody out to say, ‘Hey, we are protecting the paint.’”

Portland got back within five points in the fourth thanks to a free throw and a layup by Davina Kabantu.

Colby’s layup added a few more points to the Vikings’ lead. However, they then turned the ball over under the hoop, giving Portland some more life.

“When we play well, we play well,” Corcoran said. “When we struggle, we struggle. To the girls’ credit, it was a totally different game from last year. We fought back twice to get it to five, and if we just capitalize on a couple different plays. … But they have tremendous guards.”

That’s about the time that Oxford Hills began to dribble the ball around and take as much time off the clock as it could. Portland had to resort to fouling, presumably earlier than it had hoped, and the Vikings’ clutch shooting paved the way to a win.

“Overall, at the end of the third quarter and going into the fourth quarter we were talking about how long it was going to be before we could pull this thing out and win it, and it happened to be with about five minutes left,” Pelletier said. “They’re so athletic and so explosive that we had to slow them down, and us taking minutes off the clock, it’s one way you can slow them down.”

Oxford Hills will play 6-14 Deering in the AA North final, an opponent that many did not expect to reach this far.

However, Deering’s top guard Delaney Haines, is back from injury, and the Rams took care of Bangor in the other AA North semifinal Wednesday.

“You put Haines on that team, and they’re a totally different team,” Pelletier said. “Everybody’s roles go back to what they were used to. We are going to back to the drawing board tonight and practice tomorrow and see what we can do against them.”
