Jenna Geffert pitched a no-hitter to lead Seymour to an 11-0 victory over Trumbull in the Section I 11-12 Little League softball tournament on Friday at Stankye Field in Orange.

Trumbull went on to defeat Darien, 11-1, and Wallingford, 14-0, in the loser’s bracket, before dropping a 3-2 decision to North Branford in the loser’s bracket final.

Geffert was dominant in the circle in the Section I opener against Trumbull, striking out 10 and walking two in five innings, as Seymour cruised to the mercy-rule shortened rout.

“It was a tough one,” Trumbull coach George Ameer said. “I told them I still trust them. I want them to go home tonight and think about all of the positive things they’ve done so far because they’ve won five very game good games so far. Seymour is a very good team.”

After Geffert struck out the side in the top of the first, working around a walk and an error, Seymour scored two runs off of Trumbull starter Haley Komoroski.

Rebecca Johnson led off with a sharp single to left field, before Geffert bunted her over.

Rebecca Findley followed with a towering triple to the center-field alley and Chelsea Avila made it 2-0 with an RBI single.

Camryn Gruner drew a two-out walk and stole second base for Trumbull in the top of the third inning, but Geffert induced back-to-back infield pops to strand the runner.

“She did a great job of keeping it down,” Ameer said. “She pitched a really nice game.”

Geffert singled and stole second in the bottom of the frame, then scored two batters later on Avila’s infield hit.

In the bottom of the fourth, Geffert’s two-run single made it 5-0, before Seymour put the game away with a six-run fifth inning — aided by a slew of Trumbull errors.

“They kind of saw the game slip away,” Ameer said. “I just asked them to keep their body language strong and make sure they stay in the game.”

Trumbull rebounded to win two mercy-rule shortened games, before bowing out to North Branford on Tuesday night.

To get to the Section I playoffs, Trumbull defeated Fairfield 8-7 on July 2.
