It will be Archbishop Williams and Cardinal Spellman in the Division 3 girls South sectional finals.

Both Catholic Conference squads prevailed in the semifinals last night at Norwell High, with No. 2 seed Spellman defeating No. 3 seed Fairhaven in the opener, 62-41. Junior Reilly Poirier led the way for the Cardinals with 27 points and 13 rebounds. She was clutch from the foul line as well, going 13 for 16 from the charity stripe.

The Cardinals are still getting used to life without Jade Santos, the talented senior who sustained a brutal knee injury in the last game of the regular season. Santos remains a fixture on the Spellman team, going through warm-ups before each game and then cheering on her teammates from the bench.

"Jade's grown up so much as a person," said Spellman coach Pat Lamb. "She could be feeling sorry for herself, like it's the end of the world. But she's here, still being a leader."

Junior Kate Chuili got the start in her place and scored 10 points.

"We tell the girls all the time, 'You may not know when you're going to get your chance, but you better be ready.' Kate's done a great job," said Lamb.

Archbishop Williams advanced with a 68-38 win over No. 1 seed Westwood in the nightcap. The Bishops had a balanced attack, led by sophomore center Valerie Driscoll's 20 points and 18 rebounds. Guard Casey Capello poured in 19 points, while point guard Christine Duffy had another solid all-around game with 14 points, seven assists and five steals.

The loss marked the end of a brilliant coaching career for Westwood's Bill Riley. The long-time mentor of the Wolverines had decided earlier that this would be his final season.

"Boy, is that a good team," said Riley of the Bishops. "We knew what they wanted to do, but we just couldn't stop them."

Senior guard Jill Greenberg scored 18 points for the Wolverines, and managed to finish with over 1,000 for her career.

After splitting a pair of games in the regular season, Spellman and Archies will square off on Saturday at UMass-Boston at 10 a.m. It will be about more than just bragging rights, as the winner will get to move on to the TD BankNorth Garden.
