The Phantoms recovered from a one-goal deficit to beat Lower Moreland, 2-1, in overtime in the first round of postseason play Tuesday afternoon.
Shaina Feldman scored the tying goal - on Phoenixville's 16th penalty corner - with 14:07 remaining in regulation time.
Then, at 6:47 of overtime, Lindsay Neal slammed home a rebound of Jennie Moore's shot off the left post to lift the fifth-seeded Phantoms (15-3) to victory over the 12th-seeded Lions (13-6-1).
Phoenixville will now visit fourth-seeded Radnor in the second round Thursday afternoon at 3:30 p.m.
The Phantoms finished the day with a lopsided 22-4 advantage in penalty corners and 19-6 bulge in shots on goal.
"It was frustrating, but we never let down," said Phoenixville senior defensive back Kendall Wells. "We played strong. We really wanted it after losing the PAC-10. It is a whole new area to star and shine."
Wells and fellow defensive backs Brittany Rabena and Krista Gerstenberger had to hold up against some speedy Lower Moreland players in forward Jamie VanArtsdalen (26 goals) and Amanda Anderson.
The Lions' goal belonged to Maria McKenna on a blast from just inside the circle at 20:23 of the second half.
"We had to keep on them at all times," Wells said. "That's what I tried to do."
The overtime experience represented new territory for the Phantoms, but they responded well.
"We play better 7-on-7 because of the open field," Wells said, referring to the team speed. "We get more of an adrenaline rush and it keeps us going."
Phoenixville's Paige Henzie made the penetration on the right side of the field and sent the ball across to Moore, before Neal deposited the game-winner.
"We had so many opportunities," said Phoenixville coach John Tornetta. "It was a coaching nightmare. We dominated and pressured, but we couldn't capitalize on our opportunities. They (Lions) had everybody in the circle and we hit sticks. It was a barrage of sticks and bodies in there."
As far as the Lions' speed, Tornetta said the Phantoms did a better job of taking away the breakaways in the second half.
"We did a better job of playing the person, instead of the ball," Tornetta said. "We were overplaying the ball in the first half and they were getting too many breakaways. Krista and Kendall did a nice job of eliminating them."
Phoenixville goalkeeper Faith Handley made five key saves. She stopped a penalty stroke by VanArtsdalen with 18:19 left in the first half and then a breakaway by VanArtsdalen at 12:27.
Lower Moreland goalie Kim McKenna recorded 17 saves and was aided by a solid defense, too.
"The girls are hungry," Tornetta said. "This is the second season and this is what we stand for. It was our first overtime game so we didn't know what to expect. This is a good group. They have been playing together for so long. I was hoping their legs would hold up."
In overtime, Phoenixville used Moore, Henzie, Neal, Courtney Valko, Wells and Rabena in the field.
Lower Moreland countered with VanArtsdalen, Anderson, Maria McKenna, Brittany Scace, Gina Bellomo and Kathryn Bouldin.
NOTES ... Phoenixville senior forward Alyssa Kraynak was hit in the face with a ball off a stick with 7:20 left in the second half. She was treated at the scene.
