SACO – Julia Geaumont found a pretty good time to add to her extensive list of high school accomplishments.

Geaumont blasted the first pitch she saw in the bottom of the seventh inning over the left-field fence to lift Thornton Academy to a 4-3 victory against Kennebunk in a Southern Maine Activities Association softball game Friday.

“I was rounding second and it hit me that I actually got it over,” Geaumont said about her first career walk-off home run. “When I first hit it I thought it was a pop-up and I was like, ‘Oh no, Coach is going to be mad I went for a high pitch.’ But it was the opposite.”

Thornton Academy (10-2) has a five-game winning streak.

The home run proved to be the perfect ending to an outstanding all-around performance for Geaumont, who will attend Bowdoin College next year.

She also hit a two-run homer in the game and made a sizable impact as a pitcher.

She allowed five hits and struck out 13 — two in every inning except the seventh.

“Great performance,” said Thornton Coach John Provost. “That kid has just worked extremely hard on the field and off the field. She works year-around and always seems to elevate herself at key moments.”

The Rams (8-4) couldn’t have asked for a better start; they scored two of their three runs in their first at-bat.

Elizabeth Cable doubled and Janelle Bouchard singled to start the rally. Carinn Burns knocked in both with a two-out single. The second run scored when Bouchard beat a relay throw to the plate.

With the early lead, Kennebunk starter Hannah King held the Trojans in check for the first four innings. She allowed only two base runners and struck out six during the stretch. King finished with eight strikeouts.

“(King) had us off-balance,” said Provost. “We kept talking to the girls. We were having a hard time staying off that high pitch. I think she would have walked four or five of us but the girls just would not lay off that high pitch. We made a great adjustment in that fifth inning.”

Meghan Agger led off the fifth with a home run to right to start a surge that gave the Trojans a 3-2 lead. King struck out the next two batters but hit Morgan Dube, and surrendered her second home run of the inning when Geaumont took her deep to right.

“We jumped out on top but it would have been nice to get one more,” said Kennebunk Coach Jim Lang.

“I think we kind of let them hang around a little bit and they’ve got some big sticks.”

The Rams got back on even terms in the sixth. Bouchard led off the inning with an infield single and came around to score following a pair of throwing errors by the Trojans.

Kennebunk managed to get a runner in scoring position with two outs in the seventh, but Meg Cadigan was thrown out attempting to steal third to close the inning.
