Pete Frates takes the "Ice Bucket Challenge" at Fenway Park.

It's a girl!

Pete Frates, who is the inspiration for the ALS "Ice Bucket Challenge," and his wife, Julie, became the proud parents of a baby girl on Sunday.

Lucy Fitzgerald Frates arrived into a world soaked by people dunking themselves with ice-cold water to help raise awareness and money for the insidious disease that has left her dad, a former BC baseball player, confined to a wheelchair and unable to speak.

Lucy weighed in at 7.8 pounds and was 19 inches long. "Everybody is perfect," Nancy Frates told Steve Buckley of the Herald via Facebook.

The "Ice Bucket Challenge" has become a social media sensation across the world and helped to raise more than $100 million for ALS research.

And when Lucy gets a little older, she might enjoy these special Topps baseball cards being produced in honor of her dad.

The news of Lucy's birth was first shared publicly by Channel 5 sportscaster Mike Lynch on his Twitter feed.

Congrats to the family.

Keep the ice water and dollars flowing.
