The Scituate girls basketball team ended defending Division 2 state champion Oliver Ames' 25-game winning streak with a 46-42 victory in its season opener.

With four minutes remaining and Oliver Ames up four, the Sailor defense forced a jump ball. The possession arrow, and the momentum, favored Scituate. Kelly Martin slashed to the basket and cut the Tiger lead to two.

“We had the momentum early”, said Scituate coach Bryan Buckley “but we lost it in the third quarter and the first part of the fourth, but with that series of plays you could just feel us getting it back.”

Martin and Megan Otto, both guards, scored on the next two possessions to put Scituate up two.

With five seconds remaining and Scituate's shot-clock down to one second, junior Katie Lemire scored her first points, a jumper as the buzzer sounded that ended Oliver Ames' comeback chance.

“[Lemire] played great defense all game night, but she sure picked a great time hit that shot,” said Buckley. “She really proved her worth today.”

Martin and Otto combined for 11 of Scituate’s 14 points in the fourth.

Scituate outscored Oliver Ames 26-17 in the first half, but in the third quarter, Oliver Ames found its rhythm and finished the period up one.

The loss Oliver Ames' first since falling to Foxborough 49-45 in the season opener last season.

Caitlyn Abela led Oliver Ames with 14 points, and Scituate managed to keep Nicole Bostic, the only returning starter from last year's team, in check. She finished with five points, all in the second half.

Even though Oliver Ames lost its all-time leading scorer and Gatorade Player of the year in Lauren Batista, it returned six players, including Bostic, who was second on the team in scoring last season.

“[The win] is a huge confidence boost. We’ve had some success before, but to beat a team like O-A after giving up the lead in the third like we did, was great. We now know we can play with anyone,” Buckley said.
