They make up one-third of the Springfield (Delco) softball lineup.
Together they have helped the Cougars capture a Central League championship, reach the final of the District 1 Class AAA tournament, and earn the program's first state playoff win since 2007.
The Scarpato sisters have left their mark on Springfield softball.
There's Lauren Scarpato, a four-year starter and three-year captain. The senior third baseman is hitting over .400.
She leads the Cougars (21-4) by example. Not a yeller who will get in a teammate's face, Lauren would rather have her hard work and focus be contagious. If she sees a teammate is having trouble with her swing, Springfield coach Todd Odgers said, Lauren will help her with the mechanics. If another teammate has a bad at-bat, Lauren is there to pick her up.
That composure must run in the family. Courtney Scarpato, the squad's starting pitcher, is nothing but calm on the mound for the Cougars. Odgers called his ace "awesome" in the district and state playoffs, as she has given up just two runs in the first two rounds of state play.
The junior is a two-year cocaptain who is just as dangerous at the plate, hitting .465 this season.
Then there's Ashley Scarpato, a freshman first baseman hitting .370, who has been clutch in the postseason. The Cougars' season might have ended weeks ago without her.
In the bottom of the seventh in the quarterfinals of the District 1 Class AAA tournament, Springfield was down a run when Ashley stepped to the plate. She singled to center field, knocking in the tying run, and the Cougars captured the victory in extra innings.
"They are such a great family," Odgers said. "They are passionate about softball - they just love it. They love being there, they love playing, they love working hard."
Springfield plays Monday at 4 p.m. against Greensburg-Salem at Messiah College in the semifinals of the state tournament.
For the Scarpatos, it could be the last time all three sisters get a chance to share the same softball diamond.
They hope that's not the case. The Scarpatos want to play for a state title together.
