It was just her and an open net, but the ball sailed wide left with 20 minutes, 45 seconds to play.
"That was a little disappointment," Curry said of the chance. "I thought I had that. One of their defenders clipped my right heel. That was unfortunate."
Curry longed for another chance, and it came in overtime after a second half that saw a combined four goals.
The game entered overtime and, with 9:18 left, Curry took a pass from Molly Gingerich.
"Molly was carrying it from the outside and she crossed it over," Curry said. "I hit it and it almost looked like it was moving in slow motion."
The ball found its way into the net from a small gap between Warriors keeper Cayla Stiffler and the left post, sending the Wildcats into celebration.
"This is why we love the game of soccer," Curry said. "It was a great game. I was just so full of excitement (when the ball went in). I love this team and Dallastown and playing with these girls."
Dallastown (19-1-1) trailed 2-0 at halftime, an unfamiliar place for a team that has not lost since March 26.
"The girls had the attitude at halftime that we weren't going to leave here without the 'W,'" Dallastown coach Barry Barbush said. "I told the girls I could see us scoring four goals in the second half. They came out strong."
Dallastown struck twice in less than seven minutes. First Meagan Newmister scored at 29:55, then Kelsi Druck at 23:00.
The Warriors (9-7-2) -- who lost 6-0 to the Wildcats in the regular season -- battled back and regained the lead at 15:53 off a corner.
Susquehannock's Mackenzie Bates was credited with the goal, which appeared to hit off the hands of Dallastown goalie Becca Austin before falling into the right side of the net.
"I didn't even know she scored until about 10 minutes later," Warriors coach Nick Schiffgens said of the wild play.
Barbush added, "I think Becca slipped. She was coming at it and kind of slipped and it hit her hands and knocked it right in as I saw it."
Then it was Dallastown's turn to battle back. Newmister took a pass from Cassandra Landis, who had two assists, and beat Stiffler at 6:55 to again even the score.
"She's quick and good with the ball," Barbush said of Newmister. "She's like an Energizer Bunny. She can just go the whole time."
The fast-paced, back-and-forth second half was different than the first. Susquehannock took advantage of its opportunities and posted the lone goals of the first half.
Cassidy Mummert scored both of Susquehannock's first-half goals, getting an assist from Jeanette Wilson on the first goal and from Melissa Lynch on the second.
"They (Dallastown) had a lot of good opportunities (in the first half) and couldn't seem to find the net," Schiffgens said. "It was the opposite for us. Last time we played them, it was a tough loss. They scored first and we didn't capitalize on opportunities. This time, we were sure to put the ball in the back of the net and get a head start."
Both teams will be involved in the District 3 tournament.
Susquehannock, the 17th seed in Class AA, will travel to No. 16 Wyomissing on Monday to play at 4:30 p.m. in a play-in round game.
Fourth-seeded Dallastown will have a home game on Wednesday against the winner of Monday's Class AAA game between Northern York (13th seed) and Manheim Central (20th seed).
