These fun, illustrated chapter books for 7 to 9 year old readers feature the adventures and misadventures of the Pine City Porcupines, a hapless team, including Chad their erstwhile bat boy who's got a huge baseball card collection and sat-happy Dylan, Chad's best friend. While the team, its league and the games are fictional, the baseball cards the bat boy uses to help solve the player's problems are based on real Topps cards. Teddy "Bear" Larrabee, a slugger on the Pine City Porcupine, got his 823rd base hit on his birthday, August 23rd. And it's a home run! The Bear is a big believer in the power of numbers, so he asks the Pines bat boy Chad to retrieve the ball from the stands. There's only one problem: the crabby old fan in the ballpark who caught it has already pocketed it and isn't giving the ball back. Chad really wants to keep The Bear happy and slugging. So he's just got to figure out what the Pines' fan would be willing to trade for that special 823 ball.
