Amy Gutierrez ("Amy G" to San Francisco Giants fans) tells the inspiring story of older sister Marty, who teaches the game (and love) of baseball to her younger brother Mikey. Marty has always loved baseball and is known as "Smarty Marty" to her friends at school because she knows more about baseball than most grown-up baseball fans. However, her younger brother, Mikey, couldn't be bothered and just doesn't get it...UNTIL, Marty and Mikey attend a real baseball game, where Marty gradually teaches Mikey the ins and outs of baseball, the lingo, strategy, and more, often using real-life examples so Mikey can better understand. Before long, Mikey is no longer solely interested in the salted pretzels and garlic fries of the ballpark but is soon engrossed in the game and cheering along with his older sister.
Amy G's story appeals to both boys and girls and also defies the strong gender stereotypes that Amy herself has battled in her 16-year career as a sports journalist and reporter.
