Batting second—and perfect for Halloween—book #2 in an early chapter book mystery series where each book is set in a different American ballpark!

Mike and Kate are waiting for Kate's mom at a boring press conference in Yankee Stadium when the team official says something that makes Mike perk up his ears. There are rumors that the ghost of Babe Ruth is haunting the new stadium! A chill air blasts down a service hallway before every home game, along with various thumps and bumps. Is the Bambino really searching for his missing locker?

The Pinstripe Ghost includes a fun fact page about New York's Yankee Stadium.

Cross Ron Roy's mystery series with Matt Christopher's sports books and you get the Ballpark Mysteries: fun, puzzling whodunnits aimed right at beginning readers.
