Jordany Valdespin will get the ball back from his first major league hit.
Mets spokesman Jay Horwitz said Phillies and ex-Mets broadcaster Tom McCarthy played a role.
Valdespin's ball actually came back onto the field, but a ball girl flipped it to a boy in the stands, and the youngster left Citizens Bank Park. McCarthy put out an all points bulletin on Phillies TV. And the father of the young man recognized they were talking about his son's souvenir and contacted the Mets.
Horwitz said the father, Marty Wixted, will be treated to Wednesday's game with his family and also receive a bat in exchange for the baseball.
