Junior Brooke Zeiders made it 4-0 Selinsgrove at the halfway mark of the first half when she knocked in a rebound through the five hole.
The final goal of the first half came from Mackenna Mahan whose shot deflected off of a Danville stick and into the goal just under the cross bar.
Mahan put off surgery so she could be back in time to play in the playoffs.
"I have an ACL tear that is isolated so I missed nearly four weeks of the season and this is just my second week back," she said. "The knee is doing pretty well but it is holding me back a bit on my speed, but I am getting there."
Mahan, a senior, suffered the injury in the second scrimmage of the season. She scored the first goal of the second half to make it 6-0 Seals on a 2-on-1 fast break feed from Klingler.
Junior Caitlin Redd closed out the scoring for the Seals when she lifted the ball over the outstretched reach of Danville goalie Payton Shuman and into the far side of the goal after Shuman had made the initial stop.
"Overall, I was very pleased with our performance especially our passing and receiving work," Keiser added. "This group is a group that really gives you a true team effort."
Keiser went on to say that having Mahan back is also a good morale boost for the team.
"She's starting to get her speed back and right now she is compensating for that by playing smart and using her skills," she said.
Thursday's meeting was the third time this season the two teams had met. The Seals won 5-0 at home and 6-0 at Danville, who plays on a grass field.
