Somerset-Berkley was relentless on the attack, racking up five penalty corners in the final three minutes of Saturday’s Division 1 South field hockey final.

Senior goalkeeper Abby Campbell and the King Philip defense stood their ground.

Junior Nicole Connor connected with 15:22 remaining and the second-seeded Warriors made the lone goal stand, pulling out a 1-0 victory over high-scoring and previously unbeaten Somerset-Berkley for the championship at Taunton High.

King Philip (19-2-1) advanced to Tuesday night’s state semifinals against North champion Andover by shutting out an S-B squad (21-1-0) that had outscored the opposition, 145-6, through its first 21 games.

In the final frantic moments, junior forward Lucas Crook (34 goals this season) and the Raiders kept the pressure on but were denied by Campbell and KP’s defensive unit.

“I wasn’t nervous at all,’’ said Campbell. “I trust my corner defense absolutely 100 percent and they saved me a bunch of times.’’ She told her teammates not to get in the way of hard clap-shots and to focus on clearing the rebounds.

“Abby kept reassuring us,’’ said fellow captain Christina Hathaway. “She told us that she trusts us.’’

King Philip coach Liz Hathaway (Christina’s mother) said she had “total trust in my team defense. I knew in that situation they were prepared for whatever came at them.’’

Crook, one of two boys on S-B, had a breakaway in the first half, but his crossing pass rolled out of bounds.

“We went out there and played our game,’’ captain Liz Furfari said. “It was really important that we stuck to our game plan.’’

Division 1 North

Andover 1, Winchester 0 — Freshman Hannah Medwar continued her postseason success, scoring in overtime to lift the Golden Warriors to the North championship in North Andover.

Medwar scored two goals against Central Catholic in the semifinals. Andover (20-0-1), which last won a state title in 2011, will face South champion King Philip in the state semifinals Tuesday in Braintree.

After a scoreless 60 minutes, Andover and Winchester faced off in a 15-minute sudden-victory 7-on-7 format.

Early in OT, Winchester (20-1-1) took advantage of the extra space on the field but was unable to push anything past Andover senior goalie Julia Gordon. Andover gained possession and just 3:08 into the OT, Medwar’s shot eluded Winchester goalie Brooke Ross and the celebration was on.

“Seven v[s.] seven is tough,’’ said Winchester coach Michelle White. “It’s a matter of keeping possession and we lost possession and they had a run down the field and put the ball in the net.’’

Regulation play was even and scoreless, despite the Golden Warriors playing shorthanded for seven of the first 30 minutes because of two penalty cards.

Division 2 North

Watertown 1, Manchester Essex 0 — The streak may not be as impressive but the results were the same as the eight-time defending Division 2 state champion Raiders won the North sectional title in North Andover. Senior captain Sydney Poulin scored with 1:37 left to play to give Watertown its 19th straight win.

“[Sydney] was relentless,’’ said Watertown coach Eileen Donahue. “She wouldn’t give up on the play.’’ Watertown (20-1) will play Dennis-Yarmouth in a state semifinal Tuesday in Braintree.

The Raiders had a national record unbeaten streak of 184 games until losing to Winchester on Sept. 11. But since giving up three goals in that loss, Watertown has allowed just one goal and its defense was dominant against the Hornets (19-1-1) once again.

The acrobatic play of Hornets goalie Christina Calandra (10 saves) was the only reason the game was scoreless for so long.

“We were not connecting on our corners,’’ said Donahue. “The plays were there, and their goalie made some nice saves against us.

Division 2 South

Dennis-Yarmouth 1, Cohasset 0 — It took a perfectly executed play on a penalty corner to lift the Dolphins to the sectional championship in Taunton.

With 11:10 left in the first half, senior Anna McGaffigan received the ball on her stick, leaving just a quick flick of the wrist to give the Dolphins (20-1-2) the advantage. Only it wasn’t the play coach Mary O’Connor had called.

“It was a beautiful corner,’’ said O’Connor, explaining that a miscommunication led to a different play that was run. “I can’t get mad. Maybe they knew better than I did.’’

With its third 1-0 win over Cohasset (19-3-0) this season, D-Y will play Watertown in a state semifinal on Tuesday.

“We know who their stronger players are,’’ she said. “We knew they were fast, and we had to contain them.’’

Junior keeper Cassandra Francis denied a late push by Cohasset.

“It’s tough as a goalie, you’re in a game where you haven’t seen the ball in a few minutes and all of a sudden you’ve got a few shots in a row,’’ O’Connor said. “But she handled it perfectly.’’
