Nakrasius took a pass at the right of the cage and fired home an overtime winner to beat defending champion Harriton, 16-15, and send top-seeded Garnet Valley to the district final against Springfield (Delco).
"When we were talking about the overtime, we were talking about how we're all a team," Nakrasius said. "It wasn't just one person."
When Nakrasius scored, coach Jenny Purvis put her face onto an assistant coach's right shoulder and started crying.
"I'm too emotional," Purvis said. "It's just been something we've been working to see the last two years.
"One of our team goals has been to win the close games. This is obviously where it really matters."
Springfield (Delco) beat Great Valley, 19-11, earlier in the evening and will play Great Valley in the final at 5:45 Thursday at West Chester East.
For Springfield, Kate Ryan took off down the middle of the field late in the first half. Assistant coach Kathleen Geiger yelled for a pass, but Ryan kept going.
Geiger yelled, "What are you doing?" twice, before Ryan reached the front of the net, where she stopped and passed to Taylor De Bernardi for a goal.
Four minutes later, Ryan took a pass in front of the net and Geiger yelled a different message:
"Kate Ryan's feeling it. Kate Ryan's feeling it. Kate Ryan, you're feeling it."
In total, Ryan scored seven goals to lead Springfield to the district final for the second straight year.
"Kate Ryan was on fire," Springfield coach Keith Broome said. "That's the best game I've ever seen her play."
Emily Santana added six goals for Springfield.
The Cougars led, 11-4, at halftime, but Great Valley scored the first four goals of the second half to mount a comeback. Springfield rebounded and pulled away.
"I was a little nervous," Ryan said. "Once we started scoring, we got on top of our game."
