All the Red Lion freshman knew was she had a clear breakaway in overtime of the first YAIAA field hockey championship game.
Next thing Posey remembered was being mobbed by her teammates after scoring the game-winning goal in the Lions' stunning 2-1 victory against rival Dallastown at Papermakers Stadium.
"I didn't even know what to think," she said. "Everybody just came over to me and started screaming. I didn't even know what's going on."
The goal with 7:25 left in the 7-on-7 extra session, sparked a wild celebration as the Red Lion players sprinted off the bench to mob Posey.
Longtime Red Lion coach Carol Gillmen said she liked her chances in the reduced player overtime.
"This team is amazing, they play relentless. In overtime anything can happened," she said. "Ali has been playing the entire season as a varsity player. She is one of those type of athletes, whether she is a freshman or not, she plays with confidence."
Gillmen said she couldn't remember the last time one of her teams beat Dallastown. She believed it was back in 2001 or 2002, but after the two teams fought to a 2-2 draw on Monday, her group was confident.
"It's been a while. We've had a number of ties over the years, but they have had the upper hand," she said. "We were just confident we could get the job done."
"It was time to beat Dallastown. It's been way too long," junior Taylor Garifo, who tied the game with a late second-half goal, said. "It was a great feeling."
Still, it was the regular season Division I champion Wildcats that got on the board first and carried much of the play until late in the game.
Katie Hemberger started a penalty corner by putting the ball out to Kate Barbato, who immediately played it forward to a charging Hemberger, who put the shot behind Lion goalkeeper Gabriella Uberti.
That goal less than five minutes into the game set the tone, however, the Wildcats couldn't add to their lead, despite consistent pressure, which led to a 7-3 edge in penalty corners.
With less than 19 minutes left in regulation, Uberti made a nice save of a Dallastown shot. The Wildcats had a great chance off the resulting corner, but Red Lion defender Shanley Harlacker made a terrific save on a shot out of a scrum.
"Dallastown had some opportunities ... our defense kept us in the game," Gillmen said. "The defense maintained that 1-0 score, and we were able to tie it up. There were times Dallastown dominated, we made the plays when we needed to and kept playing. I am real proud of the team."
Red Lion was held without a shot until Garifo tied the game with 8:26 to play in regulation.
Garifo gathered a pass from Lexi Ferrell and put a sweeping shot that clipped a Wildcat stick and deflected high over outstretched Dallastown keeper Nikki Bream.
"Initially it was supposed to be a flick, but it hit the one girl's stick, then went over the goalie," Garifo said. "It was like, 'Go in.' and it dropped (in)."
The goal was the result of the Lions' first sustained time in the offensive zone of the second half, a fact not lost on Wildcats coach Jeri Myers.
"We dominated the whole game -- the whole second half," Myers said. "Red Lion was frustrated ... We did everything we needed to do, we just made one mistake at the end. It was nothing Red Lion did. Our girl made a mistake."
The Lions improved to 15-2-1 heading to District 3 Class AAA play, while the Wildcats, who entered the inaugural YAIAA tournament ranked third in the district power rankings, fell to 17-2-1.
