The NHIAA spring tournaments are one big game of Survivor.

And the Nashua area, with one postseason week down for diamond teams and lacrosse, has three survivors for the final week.

Yes, not many, and two are from Souhegan High School. And they survived two tough, close contests. The other team is one that’s used to be a Week One Survivor: the Bishop Guertin boys lacrosse team.

Here’s a look:

SOUHEGAN GIRLS LACROSSE

The No. 2 Sabers (17-1) will take on No. 1 Portsmouth (18-0) in a rematch of last year’s Division I championship game on Tuesday at 5:30 p.m. at Exeter’s Bill Ball Stadium.

It almost didn’t happen. Until Averie Curran fired a low shot to find the back of the net in the final seconds of regulation, the Sabers were looking at the end of their season vs. Pinkerton.

But instead Izzy Stevenson got the game winner in OT so they will get to try to avenge a Clippers team that beat them a year ago in the finals 12-7, and then 11-5 early in this regular season.

Of course it’s the continuation of the sister rivalry, Souhegan coach McKinley Curro-Sbordone, and Portsmouth’s JoJo Kerrigan (Curro).

But the Clippers have claimed several local teams as victims in the postseason over the years – Hollis Brookline in the Divsion II finals, Bishop Guertin a couple of years ago in the Divison I title game and Souhegan last year.

Sbordone says this is time to push through. “Our defense has been strong all season long,” she said, “and now it’s time for our offense to put a lot of points on the board.”

BISHOP GUERTIN BOYS LACROSSE

The No. 3 Cardinals (14-5) on Wednesday will get a long awaited chance for revenge against the No. 2 Pinkerton Academy Astros (16-3) at 5 p.m. at Manchester Memorial

What did the Astros do? They snapped Bishop Guertin’s long in-state win streak of 88 games a month ago in a 9-8 win.The Cards were missing two of their top scorers, Cam Hayden and Owen King, and only Hayden is back, but they’re poised. It’s more of a competition than in past years in this Final Four as No. 1 Bedford is a different team with top player Brody Helton healthy. They face No.5 Exeter in the other semi.

But the Astros are the team the Cards are after first.

“We’ve been locked in on Pinkerton since (last) Monday,” Cards coach Brian Cameron said. “We have a chance to make program and state history with six (titles) in a row, and we’ll come out fierce and hungry.

“Everything we want is right in front of us.”

SOUHEGAN BASEBALL

If you’re up for it, after the BG game head right up the highway some 25 minutes or so and see the 7 p.m. Divison II baseball semifinal Wednesday between No. 8 Souhegan (13-6) and No. 4 St. Thomas (16-5).

The Sabers are the defending champions, they got a classic 2-1 thrilling win ove Hollis Brookine in the quarterfinals in front of a large crowd in Hollis. A team led by catcher Joe Mayo, speedster Brody Smith, and pitcher Ethan Gaudet (possible Wednesday starter) have gotten up off the mat. The Sabers shocked a Cavs team that had beaten them twice and had just one loss atop the standings, and now face a Saints team that clubbed them in the regular season.

No problem. There’s been a consistent theme for this Saber team.

“We’re worried about ourselves,” Sabers coach Chris Metz said. “We don’t worry about what other teams are going to do. As long as we can control what we can control, we’re going to be fine. We’ve been preaching that since Day One – so don’t panic and play our game.”

That’s why they’e Survivors.
