Throughout the summer, the Skippers put in the work at area courses, and the result, at mid-week, was an 11-2 record and at least a share of the South Shore League title. Cohasset, just 6-7 last fall, put itself in position to clinch the title outright with a 28.5-25.5 win at Scituate on Wednesday.

The team needed a win or tie in this past Thursday’s match against East Bridgewater to clinch.

“This is definitely the deepest team I’ve had since I’ve been coaching,’’ said Torin Sweeney, in his eighth season as head coach. “They are by far the best, strongest team we’ve had since I’ve coached.’’

Tomorrow, the Skippers will put their skills to the test in the Division 3 South Shore sectional at the Pocasset Golf Club.

The key, according to senior captain Ian Quinlan, is focus.

“The best I’ve played this year is when I go out and expect nothing,’’ said Quinlan, who carries a 40-stroke average over nine holes.

“So when I look at statistics and go, ‘OK, I’ve got to shoot this, and get that,’ I most likely will not play that well. So I’m just telling [my team] to play their own game and play their best. And if they do that we should probably make it to’’ the state championships.

Quinlan won his individual match on Wednesday, 5 and 4, with a 7-over 43.

Fellow senior Chase Stebbins recalls his experience playing in the sectional tournament as a sophomore.

Sectional play “is totally different because in match play you can make a mistake and rebound from it,’’ said Stebbins, who also has a 40 average and was the medalist vs. Scituate. “In sectionals you have to be flawless. It’s all about being smart and playing smart golf.’’

Junior Morgan Grasz adds more depth.

The seniors “say don’t go in expecting to shoot as low as you can; just play your game,’’ Grasz said. “Go in hoping to play your game and you’ll do fine.’’

Sweeney points to three matches in late September as the turning point of the season. The Skippers beat Mashpee (4-1 at the time) on its home course on a Monday, beat Norwell (5-1-1 at the time) three days later, and then Abington the following day.

“That week kind of really defined our team,’’ he said. “It showed our depth and our strength in the league because we played three first-place teams and by the end of the week we were in first place alone.’’

Mansfield (13-3) is making its return to the Division 2 South Sectional at Easton CC tomorrow after finishing third a year ago.

“I thought it would be a rebuilding year,’’ said coach Sean Kelley, who graduated nine seniors from last year’s team. “But a lot of the kids on the team improved tremendously over the summer and we were able to win the league championship this year. It was very satisfying.’’

Several players have made giant strides. Sophomore Terry O’Mara, averaging just under 80 over 18 holes, has improved from 15th to second on the depth chart. Sophomore Matt Harris, 17th a year ago, is now sixth; and sophomore Brendan Callanan has zoomed from 19th to 8th.

“It was fantastic to watch and was a real nice surprise for a coach,’’ Kelly said. “It went from a thought of a rebuilding season into being a contender to going for the league championships.’’

Senior captain Tom Grant (75.0 average) will lead the Hornets into the sectionals, followed by Harris, O’Mara, juniors Adam Borque and Bobby Joice, and sophomore Brandon Weiner.

In the Division 2 South Cape Cod sectionals at Easton CC on Tuesday, Duxbury and Hingham enter the mix after strong regular seasons.

Duxbury captured first in the Patriot Keenan League with a 14-3 record, with Hingham following at 12-3.

“We can’t seem to get everybody on the same page and get everybody playing well at the same time,’’ Duxbury coach Jack Stoddard said of his team’s two recent losses to Sandwich and BC High. “That’s our goal right now, to get back on track,’’ he said.

Junior captains Billy Curley, James Magner, and Jonathan Stoddard lead Duxbury, along with junior Kevin Kuckuk and freshman Bobby O’Brien.

Stoddard’s longtime friend and rival coach, John Curran of Hingham, said his team is confident entering sectionals after its second-place league finish. He specifically credited senior Rick Darst for pushing the team along.

“He’s very unique, a gentlemanly kid,’’ Curran said.

Joining Darst at the top are senior captain Andrew Sypek and sophomores Kevin Granatino and Nick Wood.
