Trumbull High School’s softball team, winners of 15 regular-season games, saw its Class LL state tournament run end in the quarterfinals at the hands of top-seeded Southington High on Saturday.

The defending champion Blue Knights defeated the ninth-seeded Eagles 10-0.

“That team’s a buzz saw. They haven’t lost since sometime in 2013,” Trumbull head coach Cary Nadel said.

The Eagles were held hitless, until Lea Thompson led off the top of the seventh inning with a clean single up the middle.

Southington pitcher Kendra Friedt struck out 17 batters.

“She moved the ball very well around the plate, made our kids chase balls; some that they shouldn’t have,” Nadel said.

Southington scored twice in each the second and third innings, and put the game out of reach with six runs in the fifth.

Nadel was pleased with the season and pointed out that the Eagles improved on last year’s record and went deeper into the state bracket this spring.

“It was a good season. The girls played their hearts out,” said Nadel, adding that the Eagles never quit. “That’s not what our kids do. They fight game in and game out — from the first pitch to the last.”
