Old Lyme - Jacob Fenton said he doesn't take too many shots for the Old Lyme High School boys' lacrosse team. That's teammate Henry Hunt's job.

Fenton came through for Old Lyme on Wednesday when circumstances forced someone other than Hunt to score. He scored all of his game-high four goals in the third period to put third-seeded Old Lyme ahead for good. The Wildcats held off a late run by No. 14 Stonington and won 12-11 in a CIAC Class S second-round game.

"I'm not much of a shooter," Fenton said. "My teammates opened up room for me and I swung away."

Fenton added two assists for the Wildcats (15-2), who'll play host to No. 6 East Catholic in the quarterfinal round at 3 p.m. Saturday.

Hunt had a team-high 84 goals and 40 assists prior to Wednesday. He scored the game's first goal and Stonington made him a marked man.

Fenton had 19 goals before yesterday, good for third on the team.

"Henry is really our main guy," Fenton said. "Usually he gets all the work done, but they shut him off pretty well, so someone else had to step up and I took my opportunities."

Old Lyme's Nicholas Milazzo scored to start the second half and tie the game 6-6.

Fenton fired off three straight goals to give the Wildcats a 9-6 edge.

"We expected them to try shut off Henry and minimize his involvement," Old Lyme coach Mike Murphy said. "Those are the type of things that we work on in our offense. As the teams get better, you need to do that."

Old Lyme's Machlan Sawden scored next after Fenton's burst.

Stonington's Zach Poirier broke up Old Lyme's succession of goals with one of his own to cut his team's deficit to 10-7.

Fenton scored again with 44.1 seconds left in the quarter to give the Wildcats another four-goal advantage.

Ian Humphreys had three goals and three assists for Old Lyme and Hunt had two goals. Jacob Watts-St. Germain, Sal Tinnerello and Ryan Powers each added a goal.

Will Iorio scored three times for Stonington (9-8) and Poirier added two goals and two assists. Jack Riordan and Tyler Grills each had two goals and an assist and Cole Curtis had 20 saves.

Stonington took a 6-5 halftime lead after outscoring the Wildcats in the second quarter, 5-2.

"We needed to get more off-the-ball movement from our defenders to break down their defense," Murphy said. "We just needed to stabilize our offense and work for better shots. That's what we did. You saw the beginning of the second half that we started to work for better shots, got better chances. And we started to minimize some of the turnovers that were hurting us in the first half."

Stonington coach Bob Iorio said: "We made some mistakes there in the beginning of the second half that cost us. We tried to rest some of our defenders. We're playing some guys who are injured and bumped up pretty bad. We were trying to change our look a little bit, give some guys a rest, and it hurt us."

The Bears made a late run down 12-8. Grills scored with 2 minutes, 15 seconds left.

Will Iorio followed with an improbable goal that he shot over his left shoulder with his back to the net.

Riordan scored with 50.9 seconds left to cut Old Lyme's lead to a goal.

"We gave up some soft goals early," Bob Iorio said, "but we climbed out of the hole and made it interesting."
