These fun, illustrated early chapter books feature the adventures-and misadventures-of the Pine City Porcupines, a hapless baseball farm team, and their two batboys: Chad, an avid baseball fan with a huge baseball card collection, and Dylan, who doesn't know a thing about the sport. The fictional series has a unique twist: Chad solves problems by using information from Topps cards of real figures from modern baseball history.

Pine City Porcupines batboy Chad breaks an important unofficial rule of baseball: Don't talk to the starting pitcher when he's got a perfect game going, where not a single opponent has reached base. Now, because Chad opened his mouth, the entire Pines dugout is upset, and the team may lose to the second-to-last-place West Valley Varmints. Chad has to consult his baseball card collection to figure out how to help his beloved Pines pull off the perfect game.
