After waiting out a 45-minute lightning delay, the top two seeds battled for the Division 1 North girls’ lacrosse title, with host Lincoln-Sudbury defeating Andover, 12-7, Friday for its second consecutive sectional title.

“It feels great,’’ said Lincoln-Sudbury coach Debbie DeJesus. “Andover is just an incredible team, so to best them for the title it makes it even sweeter.’’

Andover (20-4) started strong, led by senior attack Ally Fazio, who came from behind the net to score the first goal less than a minute into the game. Fazio finished with two goals and three assists, including setting up Weezie Gross’s goal 10 minutes later.

“It was a crazy start to the game,’’ DeJesus said. “I just told the girls to calm down.’’

Lincoln-Sudbury (23-1) got its first break after winning a draw and setting up shop in Andover’s end. Abby Quirk opened the scoring for L-S, which began a three-goal run.

Senior cocaptain Madison Acton (four goals, two assists) did the honors with the next two goals, powering her way to the net to give Lincoln-Sudbury the 5-2 lead.

Lincoln-Sudbury senior cocaptain Rachel Sexton was also an offensive powerhouse, netting four goals and an assist.

With four seconds left in the first half, Lincoln-Sudbury took a two-minute yellow card, giving Andover the man-advantage to start the second.

The Golden Warriors took advantage with Fazio again setting up Gross for a goal to cut the deficit to 5-3.

Andover tied the contest with man-up goals after Acton took a two-minute yellow card.

After battling to stay ahead of the Golden Warriors, Lincoln-Sudbury called a timeout to try to slow Andover’s momentum.

The break was just what the Warriors needed, as they went on a four-goal streak to open up a 12-7 lead.

Lincoln-Sudbury will face Westwood in the EMass final at 5 p.m. Monday at Babson College. L-S beat Westwood, 13-12, in its season-opener.

Division 2 North Winchester 21, Ipswich 9 - After seeing her squad lose in last year’s Division 2 state final, Winchester coach Suzanne Ontso’s message to her team Friday was understandable.

“Ladies! Let’s go! You’re not done yet,’’ she barked at her players, as their celebration lingered too long for her liking.

It’s hard to blame the fourth-ranked Sachems (23-1) for being excited. The win was their 16th straight by seven or more goals and sets up a second straight trip to the Division 2 final, where they’ll face South champion Medfield.

The Sachems lost in last year’s state final to Hopkinton and it’s clear Ontso has no intentions of taking her foot off the gas until the season’s officially over.

“They’re excited, obviously,’’ said Ontso. “But we have one more big game, so we’ll see.’’

The 21 goals tied a season high for the Sachems, who ran much of their offense through Megan Hennessey. The junior midfielder, who has already committed to Harvard, had a game-high eight goals and three assists.

“Megan’s shot was on today, so she just went right at it,’’ said Ontso. “She just played a great game.’’

After falling behind, 2-1, 1:22 into the game, Winchester rallied to score 13 of the next 15 goals to take a 14-4 edge at the half.

The eighth minute was especially kind to the Sachems, who struck three times in the span of 36 seconds. Senior attack Michele Guyette (two goals, one assist) started at the 7:04 mark and Hennessey followed with two streaking tallies of her own.

Hallie Stone put forth a strong performance in net for Winchester, turning away 11 of 20 shots, and senior midfielder Emy Stratton (five goals, one assist) had a quietly impressive game.

The Tigers (16-4) scored five goals in the second half, but the damage had already been done.

Division 2 South

Medfield 9, Hopkinton 8 - Even though his team dug itself an early 3-1 hole, Medfield coach Jason Heim did not panic, and neither did his players.

“In a game like this, everybody has jitters,’’ Heim said. “Your adrenaline is flowing in the beginning of the game, and it takes a minute to settle down and figure things out. We were able to do that, and it has been a key to our success.’’

The Warriors rebounded with four consecutive goals and held on to defeat host Hopkinton

Hopkinton opened the scoring three minutes in with a goal by Tess Chandler, and took a 2-0 lead 34 seconds later on Chandler’s second. The Warriors’ Emily Zlevor put one home, but a tally from Dana Gogolin gave the Hillers a 3-1 advantage.

The remainder of the half was dominated by the visitors, with goals from Katelyn Noschese and Zlevor. Natalie Gill made it four consecutive for Medfield before Hopkinton’s Taylor Sokol broke the streak with 1:30 remaining in the half.

Chandler and Zlevor exchanged goals at the outset of the second stanza, but the teams were then scoreless until 14:02 when Gill scored her second to give Medfield an 8-5 lead.

Chandler cut the deficit to one with 1:29 remaining with a full field rush, but a steal by Medfield with 14 seconds to go preserved the victory.

“Every time we play Hopkinton it’s a barnburner, it comes down to the very end,’’ Heim said. “On any given night it’s a flip of the coin.’’
