Fasten your seat belts, the Tourney Trail is underway and it will take you nearly two weeks to navigate.

And one of the early stops will be a classic: Nashua North vs. South baseball.

That will be Thursday at 2 p.m. at Holman Stadium, the first time ever these two teams will square off in the postseason.

There are two all-local matchups on Wednesday in softball and girls lacrosse, as the Alvirne and Bishop Guertin softball teams play today, weather permitting, at 4 p.m. in the Division I prelims, and the Nashua South girls lacrosse team will be at Souhegan at 5 p.m. in the Division I quarterfinals.

There are three local No. 1 seeds: Hollis Brookline (15-1) in Division II baseball, and both the Bishop Guertin boys and girls lacrosse teams

Here’s a look at how things are locally by sport:

BASEBALL

DIVISION I – North (15-4) vs. South (7-12) highlights things in the prelims, with only top seed Portsmouth getting a bye. The other biggie will be No. 8 Bishop Guertin (13-7) vs. No. 9 Bedford (12-8) Thursday, at Manchester’s Gill Stadium at 4 p.m.

Bedford beat BG at Holman back on April 18. The winner’s reward is a trip Saturday to face No. 1 Portsmouth (18-1) in the quarters. North or South would face either Exeter or Dover; North would have to travel, South would host.

Division II – The Cavaliers (15-1) get first round bye and will take on the winner of No. 8 Kingswood-No. 9 Plymouth. They didn’t play Plymouth but beat Kingswood 10-1.

Souhegan is the third seed, and the Sabers (14-5) would host Stevens (6-10) on Thursday at 4:30 p.m.; Souhegan won the regular season matchup 11-1. A win and Souhegan hosts either No.6 Oyster River or No. 11 Lebanon in Saturday’s quarters. Milford (6-10) had quite a second half run after an 0-8 start making the tourney as the 12th seed and will trek to No. 5 Hanover (11-4) Thursday. The teams did not play earlier.

Division III – Campbell also had a good season (No. 9, 11-5) and will be at No.8 Hopkinton. The winner goes to No. 1 Monadnock on Saturday in the quarters. The Cougars lost to both during the regular season.

Division IV – The Warriors of Wilton-Lyndeborough are the No. 9 seed and will visit No. 8 Concord Christian (Both 10-6) on Thursday, and the teams did not meet previously. If they win they won’t have to go far; they’d be at No. 1, 15-1 Derryfield on Saturday, which owns two wins over the Warriors, 14-4 and 7-2.

SOFTBALL

Division I – No. Alvirne and BG are both 11-7, but the Broncos get the home game by virtue of Alvirne’s 7-3 win over the Cards back on April 20. The only other prelim involving a local is No. 12 Merrimack (10-8) at No. 5 Pinkerton (13-5) today at 4 p.m. The Tomahawks beat Pinkerton, 6-5, early in the season.

The Alvirne-BG winner gets top seed Exeter (17-1) Saturday in the quarterfinals on the road. Merrimack-Pinkerton will take on the winner of Salem-Bedford that day as well.

Division II – Hollis Brookline (10-6) goes in as No. 6 and will host No. 11 Pembroke (7-9) today at 4:30 p.m. No. 12 Milford (7-9) will be at No. 5 Kingswood (12-4). Neither of these matchups were played during the regular season. If HB wins, it goes to face No. 3, 14-2 John Stark on Saturday, while Milford would go to face No. 4, 13-3 Stevens. HB lost to Stark 8-6 just last Friday.

Division III – Defending champion Campbell is the No. 2 seed at 14-2, and will host No. 15 Somersworth (5-11) today at 4, and then if they win as expected host either No. 7 Hopkinton (12-4) or No. 10 White Mountains (12-6) in Saturday’s quarterfinals.

BOYS LACROSSE

Division I – Nothing local until Saturday, when No. 6 Pinkerton (10-8) is at No. 3 Nashua South (14-4) at 11 a.m.at Stellos in the quarterfinals. No. 2 Bishop Guertin (16-2) will host No. 7 Bedford (8-8) either at Stellos or elsewhere at a time tba (the Division II girls at Stellos creates a time conflict).

South beat Pinkerton for the first time in ages 7-3 just over a week ago while Guertin handled Bedford 15-7 on May. 9

The fun: BG and South, if they win, square off in the semis next Wednesday in Exeter.

Division II – Both locals will be on the road on Thursday in the prelims. No. 13 Hollis Brookline (6-10) is at No. 4 Timberlane (12-4) at 5 p.m, and the Cavs gave the Owls a hard time, 8-6, back on May 17. No. 14 Alvirne (6-10) is at No. 3 Windham (13-3); the Broncos lost twice to the Jags, 15-2 and 20-4 during the season. If there are upsets, HB gets winner of No. 5 St. Thomas-No. 12 Memorial-Central, and Alvirne would be at either Winnacunnet or Goffstown in Saturday’s quarters.

Division III – The powerful Campbell Cougars get a first round bye and host Thursday’s winner of No. 8 Kearsarge vs. No. 9 Gilford in the quarterfinals on Saturday. They beat Kearsarge 12-6 and Gilford 13-7 back-to-back at home in April. The semis are next Wednesday at 7:15 p.m. at Laconia’s Bank of New Hampshire Stadium.

GIRLS LACROSSE

Division I – Today is a biggie with No. 5 Nashua South (13-5) at No. 4 Souhegan (12-3) at 5 p.m. in Amherst, a rematch of a great 12-10 game, won by the Sabers, back on April 30.

Meanwhile, Bishop Guertin will host No. 8 Exeter (9-9) at 5 p.m. at Stellos, a team the Cards beat 18-7 this spring. The key here is that Guertin, with an expected win, would face local South or Souhegan in Saturday’s semis at Exeter’s Bill Ball Stadium at 7 p.m.

Division II – No. 3 Hollis Brookline (13-4) will host No. 6 Goffstown (11-5) today at 5 p.m. in the quarterfinals; interestingly enough the Cavs beat the Grizzlies 13-7 in the season opener but lost 12-11 in the regular season finale. The winner goes directly to the semis at Stellos at 5 p.m. Saturday vs. either No. 2 Hanover or No. 7 Pembroke. The finals are next Wednesday at Stellos at 7 p.m.

Division III – Today No. 5 Campbell (10-5) is at No. 4 Derryfield (10-3) at 5 p.m.; the Cougars lost 14-6 during a regular season meeting.

The winner faces either No. 1 Bow or No. 8 Pelham in the 7 p.m. semis at the Bank of New Hampshire Stadium on Saturday in the semis.
