“I give this book 4 out of 5 smiles.”—Michael Roberts, Reporter, Age 9 - Newsday/Kidsday
“The comically deadpan reactions of Slump observers, the tautly drawn action scenes, and the snappy pacing of the short chapters are nicely pitched to readers just hitting their stride with full-length novels.” - Bulletin of the Center for Children’s Books
“Straightforward, sunny.” - ALA Booklist
“Hits it out of the park. Full of funny characters and fast-paced action (on and off the field), this series may be just the ticket for kids who live and breathe America’s pastime.” - Family Fun Magazine
“Markey’s deadpan delivery renders his tall-tale names and broad, punning prose quite comical, and the Walloper’s triumphant out-of-the-park home run is the stuff of minor legend.” - Kirkus Reviews
“A lively…read [for] fans of Matt Christopher’s sports stories, or readers who simply appreciate play-by-play action.” - School Library Journal
