He kept Wareham on its heels with his ability to beat the defense off the dribble and driving to the hoop. Seniors Anthony Parham and Dean Kennedy each had 16 points. The Vikings were led by Jules Tavares, who had 27 points, while Patrick Murphy scored 20 and Jordan Rezendes added 17.

It was a back and forth game all night, with Scituate jumping out to an early lead. The Sailors led, 38-36, but Wareham rattled off nine straight points before Beldo's runner beat the buzzer as Scituate trailed, 45-40 at the half.

Wareham looked to be pulling away when the lead grew to 54-44 early in the third quarter, but Scituate called time out and quickly regrouped, going on a 12-0 run for a 56-54 lead. The Vikings battled back though, to lead 60-58 after three quarters.

Early in the fourth quarter, Wareham led, 65-62, before Kennedy buried a three with 5:26 remaining to even the score and key a 17-6 run as the Sailors took control with a 79-71 lead. From there, the two teams traded baskets as Scituate held on for the win. The Sailor's will play the winner of Wednesday's game between Pembroke and Abington on Saturday at UMass-Boston.

The following was compiled by Globe correspondent Evan MacDonald and will appear in Wednesday's Boston Globe.

Division 1 North: Lexington defeated East Boston, 85-61, as David Miller (15 points) and Danny O'Keefe (10 points, 8 rebounds, 4 blocks) led six Minutemen in double figures. Lexington exploded in the second and third quarters, outscoring East Boston by 29 points to advance to the semifinals against Lynn English.

Division 1 South: Needham senior Katherine Horn had only 2 points entering the fourth quarter against Newton South, but she didn't finish the game quietly.

With a minute left in regulation, Horn drilled a 3-pointer to lift the Rockets into a 41-41 tie - their first of the night. And for a team that trailed for 31 minutes, the shot was just the spark it needed.

Horn hit another 3-pointer with less than two minutes left in OT, giving the Rockets the lead, and they never looked back.

Needham won the semifinal thriller at Massasoit Community College in Brockton, 51-47, and coach Kimberly Benzan credited her seniors for their gutsy performance.

"I have four seniors and they kept saying, 'This is our game,' " Benzan said. "We really believed that this was our year."

Despite the offensive efforts of Newton South guards Chloe Rothman (16 points), Sophie Bikofsky (14), and Kendall Burton (13), Needham's heightened defense in the second half helped close the door.

"I think that they shot exceptionally well from the outside," Benzan said. "[But] we matched their defense with our defense."

Benzan added that the Rockets' balanced offense led by sisters Kathryn and Christine Ganser, who notched 14 and 11 points, respectively, made it difficult for the Lions to guard them.

"We're not a one-trick pony," Benzan said.

Needham will face Brockton Saturday in the final. The Lady Boxers defeated Bridgewater-Raynham, 46-29, at Massasoit behind a 16-point performance from senior Sabree Rodriquez and 14 points from senior Beatrice Atkinson. Freshman Kelly O'Neill led the Lady Trojans with 10 points.

Division 3 North: Mike van Siclen's four goals pushed Concord-Carlisle past Weston, 8-2. Mike O'Brien had three assists and John Nessa stopped 21 shots for the Patriots. In the final, Concord-Carlisle will face Shawsheen, which beat Marblehead, 2-1, in a shootout.

Division 1: Woburn advanced to the state championship, defeating Hingham, 3-2, in overtime behind a hat trick from senior Colleen Callahan. After Woburn fell behind, 2-0, Callahan scored on a feed from Colleen Martell late in the second period and the duo hooked up again in the third to force extra time. Callahan completed the hat trick with 1:36 remaining. Woburn will face St. Mary's Saturday in the first girls' hockey championship at TD Banknorth Garden. St. Mary's defeated Arlington, 3-2. Mikaela Donovan and Genevieve Benoit each had a goal and an assist for St. Mary's.
