This MLB baseball trivia for kids quiz is written for young fans aged about 7 to 12, and for the parents, coaches and teachers who quiz them. It covers how the game works (innings, strikes, walks, home runs and grand slams), the teams and ballparks every kid hears about (the Yankees, Dodgers, Red Sox, Cubs, Fenway and Wrigley), the heroes of the past and present (Babe Ruth, Jackie Robinson, Hank Aaron, Derek Jeter, Shohei Ohtani and Aaron Judge), plus the fun stuff: mascots, the seventh-inning stretch, Cracker Jack, Little League and what is actually inside a baseball. Every question is one a young fan can get right or learn from, and each answer comes with a short fact worth repeating at the ballpark. There is nothing here about salaries or scandals. It works for a team bus ride, a rain delay, a classroom or a birthday party. All the answers were checked against Wikipedia and MLB records, so grown-ups can read them out with confidence.
