If pressure is defined by either exorbitant expectations or competition nipping at its heels, Edward Little should be nice and relaxed heading into Saturday’s Class A track and field championship at Brewer Community School.

The team championship is expected to be a spirited scrap between Cheverus and Scarborough. Next in line and living somewhat on an island are the Red Eddies.

“Cheverus is probably the favorite, Scarborough is right behind, and we’re kind of in no-man’s land. We’re seeded quite a ways behind them and quite a ways ahead of the rest of the pack,” Edward Little coach Ryan LaRoche said. “We’ll see. Anything’s possible at a state meet.”

Lisbon’s two teams enter the Class C competition at Foxcroft Academy in a similar you-never-know frame of mind.

The Greyhounds handicap at a distant third in the girls’ meet behind Orono and Traip.

According to seed, Foxcroft, Orono, Central and Fort Fairfield all check in ahead of the Lisbon boys in what shapes up as a tight race.

McMann Field in Bath hosts the Class B state meet, where local teams aren’t in the title picture but plenty of area athletes are.

Here’s a breakdown of what to expect at each site:

Class A

Barring an EL upset, Class A boys will crown an astonishing 11th different team champion in 12 years. Cheverus hasn’t won the title since 1998. Scarborough’s last championship, in 2001, came in Class B.

The Eddies are slotted more than 20 points behind the SMAA powers and 30 ahead of host Brewer and KVAC foe Brunswick in the chase for third.

EL knows how quickly such a big deficit can be made up on race day, because the Red Eddies have been on the other side of the equation at the two most recent KVAC championship meets.

An injury to standout jumper Connor Harris brought EL back to the pack in 2012, and Lewiston tied its riverside rival for the title.

This past Monday, disqualifications of an apparent winner in one distance race and one of the co-favorites in another erased EL’s expected edge over Lawrence. It took a third-place finish in pole vault and second in 4×400 relay — the final two events — in order for the Red Eddies to rally and win their 10th straight league championship.

“Lawrence kind of showed that you can make up points with a few good things happening for yourselves and a few not-good things happening for other teams,” LaRoche said.

Harris is healthy this season, and that’s great news for the Eddies’ aspirations. He is the top seed in triple jump by more than two feet, and also is ranked second in high jump and third in long jump.

Senior Lucas Bourget is seeded first in the 1,600 and 3,200 meters, and freshman Spencer Dunn is ranked No. 1 in the race walk.

EL also looks for points from Adam Robinson (race walk), Aswan Duncan (300 hurdles), Bourget (800) and Roger Charest (400).

Lewiston’s 4×800 relay quartet of Mohamed Mohamed, Mohamed Awil, Mohamed Barre and Isaiah Harris is seeded first. Barre and Mt. Blue’s Justin Tracy will challenge Bourget in the mile and two-mile.

Class A girls will have a new champion, with Scarborough a non-factor after winning five of the previous seven state titles. A three-team scramble between Bangor, Bonny Eagle and Brewer should materialize.

EL is unlikely to reach its runner-up finish of a year ago, but an event title is well within reach for the 4×100 relay of Ayumi Ranucci, Ashley Joyner, Avery Chisholm and Lexi Clavet.

It will be a busy and rewarding day for Clavet, who also is the top seed in triple jump and will be in the mix in long jump and pole vault, as well, before graduating Saturday night.

“He (coach Calvin Hunter) has always crammed four events for me each meet, just to get the hang of it,” said Clavet, who will compete at Ithaca (N.Y.) College next year.

Joyner (300 hurdles) and Chisholm (200) also have title hopes.

Class B

Two likely themes of the meet: Waterville going for a sweep, and Lake Region’s Kate Hall (sprints, hurdles) and Waterville’s Bethanie Brown (distances) chasing history on the girls’ side.

Hall is seeded faster than the existing records in the 100 and 200 meters. She set the 100-meter mark a year ago as a freshman. The 200-meter standard has stood since 1983. UConn-bound Brown is expected to dominate the 1,600 and 3,200.

Local girls to watch include defending high jump champion Hope Kohtala, who is tied for the No. 2 mark heading into the meet. Poland’s Emma Turton (100, 200), Spruce Mountain’s Brooke Steele (race walk) and Leavitt’s Bri DeGone (javelin) and Ashley Pratt and Jackie Gauthier (pole vault) are seeded to score points.

Gray-New Gloucester has a shot at top-five in the boys’ meet on the shoulders of No. 1 seeds Will Shafer (800 and 1,600) and Elijah Locke (high jump).

Sam Brenner of Spruce Mountain is the favorite in the race walk. Alwayne Uter will contend for the Phoenix in the javelin.

Class C

Lisbon received 40 points from Kayla Angelico on its way to an eighth straight MVC girls’ championship, and another perfect day isn’t out of the question. Angelico is seeded first in javelin and the 4×800 relay and third in the 300 hurdles and 4×400.

Olivia Bulgin (race walk), Adrianna White (800), Bree Sautter (400) and Gabby Ouellette (high jump) all have their eyes on individual honors.

Winthrop’s Rachel Ingram (triple jump), Dirigo’s Kayla Gaudin (shot put) and Ellen Tuttle of St. Dom’s (race walk) each are seeded among the top three.

Another St. Dom’s athlete, Marley Byrne, could score in three events — 100, 200 and triple jump.

Most of the likely Lisbon boys’ points are in the race walk, where Tyler Bard, Ben Kates and Jake Angelico are seeded first, second and fourth, respectively. Kates is a contender in the 800, while Aaron Halls is a triple threat in the 100, 4×100 and long jump.

Marcques Houston of Monmouth is the top seed in the 400. The Mustangs are rated tops in the 4×400 and 4×800, as well.

Josef Holt-Andrews of Telstar is favored in the 1,600 and 3,200. Robbie Pallozzi of St. Dom’s ranks second in javelin.

Among the team favorites, Foxcroft has never won a state track title, and Orono seeks its first in 16 years.
